Description

Thermal image shooting device and thermal image shooting method

Technical Field

The invention discloses a thermal image shooting device and a thermal image shooting method, and relates to the application fields of thermal image shooting devices, thermal image processing devices and thermal image shooting.

Background

The thermal image shooting device is widely applied in the fields of industry and the like, and the regular infrared detection of power equipment, buildings and the like is an important part of state maintenance.

Infrared thermography is different from visible light images, and in the captured visible light images, the captured objects can be confirmed through information in the images, such as colors, nameplates, shapes and the like, so as to identify the objects; the infrared thermography is not easy to confirm the shot specific shot object through the information in the image, and if the shot specific shot object cannot be effectively identified through colors, nameplates and the like, a user is very easy to miss shooting when shooting.

The infrared detection work is quite heavy, and for example, a 500KV electric power substation usually has dozens of equipment areas, each equipment area has dozens of objects to be subjected to infrared detection, and the objects to be subjected to infrared detection have many similar objects to be photographed, and the similar objects may be the same or different types. For example, a plurality of groups of shot objects with different equipment areas exist in a transformer substation, the plurality of groups of shot objects may be adjacent to each other, and even if three different shot objects with the same shape and different numbers A, B, C are still existed in the same group of shot objects, since the different shot objects with the same type are almost the same in the infrared image, a user holds a portable thermal image shooting device, shooting is easily omitted, shooting is mixed and disordered, and the efficiency is reduced; this situation is exacerbated when multi-angle shooting is required, or when multiple parts (e.g., specific parts, specific locations) of the same subject are shot.

At present, a photographer uses a portable thermal image shooting device to select a shot object to be shot according to subjective experience, and due to the reasons and the like, the detection efficiency is low, the working strength is high, and the shot object is easy to be shot by mistake and missed.

In addition, at present, thermal image files obtained by shooting by a thermal image shooting device generate file names according to time or sequence numbers; for subsequent archiving, analysis and arrangement, and distinguishing thermal image files corresponding to a shot object, during infrared detection, a user is required to correspondingly record shot object information according to a field nameplate recognized or recognized by the shot object, and the existing common recording mode, such as manual paper recording of the file name of the thermal image file and the corresponding shot object information, such as attaching voice annotation of the field shot object information to the thermal image file, is adopted; the above methods have various inconveniences such as inconvenient operation, easy error, influence on the shooting speed, large subsequent arrangement workload and the like.

Since the application of the thermal image detection technology, no proper means is provided for conveniently realizing information prompt of a shot object, a user often feels confused in shooting, and technicians in the field always try to solve the problem, for example, a thermal image shooting device provided with a GPS device can prompt GPS prompt information in shooting of a power line; however, the user is not easy to correspondingly understand the specific object to be shot through the GPS information; when a plurality of objects are densely located at the same position and need to be photographed individually, specific objects cannot be dealt with. The prior art also does not solve the problem that shooting is easy to miss, and how to guide a user to carry out infrared thermal image shooting is a difficult problem.

Therefore, it is understood that there is a need for an infrared camera that can conveniently provide the prompt information of the subject for the user to shoot the subject, and the user can perform thermal image shooting according to the instruction of the prompt information of the subject, thereby solving the existing problems. Moreover, when the object prompt information of the user for shooting the object is provided, the problems that the object information is easy to be mistaken and the operation is inconvenient to record manually and the like are solved.

The control unit 10 controls the overall operation of the thermal image system 13, and the flash memory 9 stores a program for control and various data used for controlling each unit. The control program enables the control part 10 to execute the control of processing in various modes, after the power is switched on, the control part 10 initializes the internal circuit, then, the standby shooting mode is entered, namely, the shooting part 1 shoots to obtain the thermal image data, the image processing part 2 carries out the specified processing on the thermal image data shot by the shooting part 1 and stores the thermal image data in the temporary storage part 6, the control part 10 executes the control on the display control part 3, the infrared thermal image is continuously displayed on the display part 4 in a dynamic image form, in the state, the control part 10 implements the control and continuously monitors whether the processing is switched to other modes or the shutdown operation is carried out according to the preset conditions, and if the processing is carried out, the corresponding processing control is entered. The control unit 10 is realized by, for example, a CPU, an MPU, an SOC, a programmable FPGA, or the like.

In the present embodiment, the control section 10, as an information specifying section, displays an example of a control section and a progress statistic section. In this embodiment, a scene in which a user performs infrared detection on a subject whose device types are device i, device ii, and device iii in a device area 1(1001), a device area 2(1002), and a device area 3(1003) in a substation 1 shown in fig. 10 is taken as an example; before the main shooting, data files of the subject information to which the sort order is added are stored in advance in the flash memory 9 (or in a storage medium such as the memory card 8 or the temporary storage unit 6). The present embodiment is explained with reference to fig. 3 to 10. Referring to fig. 3, the control steps are as follows:

in step S101, the control unit 10 performs control to continuously detect whether the user selects the information mode through the operation unit 11.

If yes, go to step S102; the control section 10 transfers the subject information (partially or entirely) added with the sort order stored in the flash memory 9 to the temporary storage section 6, and the transferred subject information may be all of the subject information or predetermined partial information, for example, predetermined partial information for obtaining subject instruction information. Further, after the power is turned on, the information may be transferred to the temporary storage unit 6.

In step S102, object information as special object information is specified.

In another embodiment, the control unit 10 monitors whether or not there is an operation instruction to select the special object information; here, in a case where the operation instruction is confirmed, the subject information corresponding to the selected subject instruction information is designated as special subject information; a display control unit for controlling the display unit to display a predetermined number of pieces of subject instruction information based on the plurality of pieces of subject information added with the sort order stored in the information storage unit; an information specifying unit specifies subject information as special subject information based on a user's selection. For example, in the object instruction information shown in the object information display field 601 of fig. 6, the user can select one of the object instruction information through the operation section 11, and the control section 10 designates the object information corresponding to the object instruction information as the special object information. In addition, the user can also enter a display interface of new shot object indication information by means of page turning, scroll bar moving and the like, select the shot object indication information and specify special shot object information; further, the subject information as the special subject information may be specified from the starting point of the previously default sorting order, for example, the subject information as the special subject information which was last specified when used last time, and the subject information next to the sorting order thereof as the currently specified starting point.

Step S103, transmitting the thermal image data obtained by shooting through the shooting part 1 to the temporary storage part 6; the image processing unit 2 performs predetermined processing such as pseudo-color processing on the thermal image data captured by the imaging unit 1 to obtain image data of an infrared thermal image, and stores the image data in the temporary storage unit 6.

And step S104, the control part 10 controls the display part 4 to display the infrared thermal image generated by the thermal image data and specially display the shot object indication information obtained by the appointed special shot object information.

The object indication information and the infrared thermal image are jointly displayed in the display interface, and the object indication information and the infrared thermal image can be superimposed in the infrared thermal image and/or not superimposed in the infrared thermal image.

The special display is, for example, as shown in fig. 7, as the object instruction information obtained by displaying only the specified special object information.

The special display is, as when the subject instruction information obtained by the prescribed number of subject information not limited to the special subject information is displayed, wherein the subject instruction information obtained from the specified special subject information is specially displayed in a display manner distinguished from other subject instruction information.

In a preferred embodiment, the display control unit controls the display unit 4 to display the infrared thermal image generated from the thermal image data, and displays the subject indication information obtained from the specified special subject information in a display manner distinguished from other subject indication information, based on the subject information added with the sorting order stored in the information storage unit (determined by the task determination unit when there is the task determination step), and in the sorting order, displays the subject indication information obtained from the specified special subject information.

As shown in the display interface 601 in fig. 6, the control unit 10 controls to display object instruction information obtained by displaying a predetermined number of pieces of object information in order, and the underlined mark of "substation 1 equipment area 1 device ic phase" may be distinguished from other pieces of object instruction information, or may adopt a special display mode distinguished from other pieces of object instruction information by a difference in display position, color, background, size, font, caption, or the like which is easily recognized by a user, and perform caption "taking with the object instruction information displayed specially as shown in fig. 8: and a display interface of the 1 equipment zone 1 equipment IC phase of the transformer substation 1.

In another preferred embodiment, the display control unit displays predetermined information for generating the subject instruction information among the subject information in a hierarchical manner, that is, in a predetermined hierarchy and attribute information corresponding to each hierarchy. The hierarchical display is, for example, a tree display, and as shown in a subject information column 901 in fig. 9, the control section 10 displays the subject instruction information in predetermined three layers and in predetermined positions according to the attribute information of the predetermined attribute of the substation, the equipment area, the equipment type, and the other; specially displayed subject indication information 902 is also superimposed in the infrared thermal image for easy observation by the user.

Specifically, in one display control implementation, the image processing unit 2 is controlled to synthesize image data of an infrared thermal image generated by thermal image data obtained by shooting and image data of subject indication information obtained by specified special subject information; storing the synthesized image data in a temporary storage unit 6; then, the display control unit 3 is controlled to display the synthesized image data on the display unit 4. As shown in fig. 7, wherein the synthesis superimposes the object indication information in the infrared thermal image at a prescribed transparency ratio. When there is other predetermined instruction information, the image processing unit 2 is controlled to combine the image data of the infrared thermal image generated by capturing the obtained thermal image data, the image data of the specially displayed object instruction information obtained by the specified special object information (when there is a specially displayed mark, the image data including the mark as a dashed line), and the image data of the other predetermined instruction information; and controls the display control part 3 to display the synthesized image data on the display part 4, as shown in fig. 6, the synthesis combines the subject indication information and the infrared thermal image, and displays the combined image data in different areas without overlapping each other or with a small amount of overlap. Other instruction information includes a predetermined number of pieces of subject information, and instruction information such as date and battery capacity displayed on the display unit.

The object instruction information obtained from the object information may be obtained as all or a predetermined part of the object information, and the configuration of the information for obtaining the object instruction information in the object information may be predetermined.

Wherein the control section 10 functions as a progress counting section for counting the shooting progress information on the basis of the number of the subject information to which the sorting order is added (determined based on the task determining section when there is the task determining step) stored in the information storage section and the currently specified special subject information; the control section 10 controls the display of progress information, such as progress information 603 displayed in 601 in fig. 6 and progress information 604 displayed in 602; note that, in fig. 6, in the case where the order indication information (number) of the specifically designated subject information has already been displayed, the number may also constitute progress information with the total number "15" of the displayed subject information.

Note that the sort order corresponding to the subject information may be displayed or not, and in fig. 6, order instruction information (serial number) obtained from the sort order information corresponding to the subject information to which the sort order is added stored in the information storage unit (when the task determination unit determines that there is a task determination step), is displayed.

Step S105, the control part 10 judges whether a switching instruction operation exists, if not, the steps S103-S105 are repeated, the object instruction information and the continuous dynamic infrared thermal image are displayed together, and if the switching instruction operation of the object information exists, the step S106 is executed.

The user takes specially displayed shot object prompting information 'substation 1 equipment area 1 equipment IC phase' as the prompting information for shooting the current shot object, the shot object indicating information comprises information representing the identity of the shot object, and the corresponding shot object is checked and shot by checking the cognition of the corresponding shot object or the equipment identification plate; when the user finishes shooting the subject, the user presses the switching key 02 (e.g., a key representing a switching instruction operation) of the operation unit 11 to perform the switching instruction operation by one-key operation, and the user does not need to look at the subject information shown in the display interface 601 in fig. 6 to perform selection or search, which is simple in operation.

Further, the control unit 10 may be configured to perform the switching operation based on a predetermined switching condition; for example, when it is determined that a predetermined time interval is met, for example, the temperature value in the thermal image exceeds a predetermined threshold, for example, when a predetermined switching condition such as a trigger signal of a device connected to the thermal image device 13, for example, another sensor device is received, the process automatically proceeds to step S106 even if the switching instruction operation of the operating unit 11 is not performed; the predetermined switching condition may include a process of performing a switching designation when other predetermined conditions, such as a predetermined time interval or a temperature value in the thermal image exceeding a predetermined threshold, are simultaneously satisfied even if the switching instruction operation of the operating unit 11 is performed.

In step S106, the control unit 10 determines whether or not the task is completed.

In response to the switching instruction operation, the control section 10 judges whether or not the designation of the last subject information in the sorting order sequence is completed; if not, the process returns to step S102, and at this time, the designated special object information is switched in the order of the order based on the object information to which the order is added, which is stored in the information storage unit. If the operation is finished, the information mode is finished, characters such as 'task completion' and the like can be displayed on the screen, and then the thermal image device returns to the standby state to wait for the user to enter the operation of other modes. Alternatively, the imaging may be performed by switching to a predetermined starting point of the sort order, for example, the starting point of the sort order.

Specifically, in one embodiment, the information designating unit (control unit 10) adds 1 to the sequence number of the sorting order corresponding to the special subject information designated before the switching, and then determines whether the last one in the sorting order sequence is completed, and if the last one in the sorting order sequence is not completed, searches for and designates the subject information corresponding to the sequence number of the sorting order obtained by adding 1 to the sequence number of the sorting order as the special subject information; and if the operation is finished, exiting. Further, it is not necessary to judge whether or not the designation of the last object information in the sorting order sequence is completed, and it may not be judged that the information mode is ended until a prescribed timing is exceeded or until the control section 10 receives an exit instruction, every time the switching instruction operation is received, that is, the object information corresponding to the sorting order number obtained by adding 1 to the sorting order number is designated as the special object information, and when the special object information is not found, the 1 is continuously added for the search until the prescribed timing is exceeded.

Returning to step S102, the information specifying unit switches the specified special object information (i.e., switches the specified object information as the special object information) based on the sort order.

In a preferred embodiment, the information specifying unit switches the single object information specified as the special object information from the single object information specified as the special object information before switching to the next object information in the sorting order sequence (the sorting order sequence of the object information determined by the task determining unit when there is the task determining step). For example, in this example, the single object information designated as the special object information is switched from the single object information "substation 1 equipment area 1 device ic phase" designated as the special object information before switching to the next object information "substation 1 equipment area 1 device ib phase" in the sorted order "designated as the special object information before switching.

Then, the display control unit controls the display unit to display the infrared thermal image generated by the thermal image data, and displays the subject indication information obtained by switching the designated special subject information by the information designating unit in a special display mode. As shown in the display interface 602, the subject instruction information "substation 1 equipment area 1 device ib phase" obtained by switching the specified special subject information "substation 1 equipment area 1 device ib phase" by the information specifying unit is displayed in a special display manner. The progress information 603 displayed in 601 is changed to the progress information 604 displayed in 602. The user can shoot the corresponding shot object according to the specially displayed shot object indication information of the equipment I B phase of the equipment area 1 of the transformer substation 1. This allows the user to easily perform imaging through the imaging path L10 shown in fig. 10, and thus the user is less likely to miss an object.

The information specifying unit switches the single object information specified as the special object information from the object information specified before switching as the special object information to the object information specified before switching as the last object information in the sorting order. The switching is performed based on the sort order, which may be the order of the sort order sequence or the reverse order, and it may be specified whether the switching is performed in the order of the sort order or the reverse order.

Further, when the information specifying section specifies the subject information as the special subject information as two or more pieces of subject information adjacent in order; the information designating unit sorts the specified specific number of pieces of the adjacent object information by the specific number of pieces of the adjacent object information designated before switching to the specific number of pieces of the adjacent object information starting from the next object information in the sorted order series of the specified object information designated before switching.

For example, when "equipment zone 1 of substation 1, equipment zone 1, equipment ib of substation 1, and" equipment zone 1, equipment ia phase of substation 1 "are designated at the same time, in response to the switching instruction operation, the switching designation" equipment zone 1 of substation 1, equipment ia, equipment zone 1 of substation 1, equipment iib of substation 1, and equipment zone 1, equipment iic phase of substation 1 "are used as the special subject information.

Further, when the information specifying section specifies the subject information as the special subject information as two or more pieces of subject information adjacent in order; there may also be cases where switching is done in reverse order.

It should be noted that in this embodiment, the information of the object with a small number is exemplified, and in the actual infrared detection operation, the number of objects is large, and the effect of the embodiment of the present invention is significant.

Similarly, for complex equipment or the situation that multi-angle shooting is needed, relevant object information and the sequencing sequence thereof can be pre-stored for objects (such as components, angles and the like) needing to be shot separately, and omission of shot parts can be avoided.

As described above, based on the plurality of pieces of subject information to which the sorting order is added, the subject indication information and the infrared thermal image obtained by specifying the special subject information and displaying the special subject information on the display unit 4 in particular, in the present embodiment, the subject information includes information representing the location (such as a substation, an equipment area), the type (such as a transformer, a switch, and the like, which are types of electric equipment), the number (such as a phase difference, and the like) of the subject, and the particularly displayed subject indication information includes information representing the identity of the subject, which can facilitate the user to confirm the photographed subject. The user regards the specially displayed shot object indication information as the indication information of the shot object currently, the cognition of the shot object or the checking of the equipment signboard confirms the shot object, and the condition of error shooting is reduced; when a switching instruction operation is performed, that is, the specified special subject information is switched in the sorting order, and the subject instruction information obtained by switching the specified special subject information by the information specifying section is displayed in a special display manner. The purpose of prompting the user of the shot objects which need to be shot at present according to the sequencing sequence is achieved, therefore, the user can easily realize shooting by the shooting path L10 shown in FIG. 10, the condition of wrong paths or disorder is greatly reduced, and omission is avoided; thereby improving the shooting efficiency, reducing the working strength and being simple to operate. Wherein, through the display of the statistical shooting progress information, the user can reasonably arrange the shooting progress. In summary, example 1 is a preferred embodiment, although it is not necessary that all of the above advantages be achieved simultaneously in any one product that embodies the invention.

Example 2

In the present embodiment, in the thermal image device 13 having the same structure as that shown in fig. 1, a control program for setting a filtering condition by a user and a control program for determining object information according to the filtering condition are stored in the flash memory 9, and the shooting task of this time is to shoot an object whose object type is the object i in the substation 1. In the past, when the detection purposes are different, all objects in the whole station are detected, and specific types of objects are also detected, and the specific types of objects are distributed in different equipment areas, so that a user needs to search for the objects, and the detection is very inconvenient.

The present embodiment is explained with reference to fig. 11 to 16.

In step S201, the control unit 10 performs control to continuously monitor whether the user selects the information mode through the operation unit 11, and if so, the process proceeds to step S202.

Step S202, setting filtering conditions;

and a task setting part for setting a filtering condition by a user, wherein the filtering condition is composed of a keyword related to the filtering condition and a filtering logic relation.

The task setting part is provided with a keyword determining unit, a logic determining unit and a filtering condition generating unit, wherein the keyword determining unit is used for determining keywords related to filtering conditions; a logic determination unit for determining a filtering logic relationship of the keywords related to the filtering condition; and a filtering condition generating unit for generating a filtering condition according to the keywords related to the filtering condition and the specified filtering logic relation.

The keyword related to the filtering condition may be one keyword or a plurality of keywords; wherein the plurality of keywords includes representing a range of keywords such as a numeric range, an alphabetical range, a sort order range, a time range, and the like. In addition, when the subject information includes various information such as the attribution unit, classification level (for example, voltage level, importance level, etc.), model, manufacturer, performance, and characteristics, history of past shooting or inspection, date of manufacture, and lifetime, which are related to the subject, the keyword may be determined from the information to set the filtering condition.

A keyword determination unit for determining a keyword related to the filtering condition; for example, one or more of the following embodiments may be combined to determine keywords related to filtering conditions.

One embodiment, for example, pre-stored keywords, determines keywords associated with the filter criteria based on user selection. As when the subject information as shown in fig. 5 is stored in the information storage portion, keywords for selection may be prestored, and the keyword selected by the user is determined as the keyword related to the filter condition.

One embodiment, for example, defaults to one or all of the keywords associated with the filter criteria.

One embodiment, for example, enters keywords by the user, and determines the keywords entered by the user as keywords related to the filter condition.

One embodiment, for example, provides a selection item of the selected keyword attribute, and determines the keyword corresponding to the keyword attribute as the keyword related to the filtering condition based on the keyword attribute selected by the user; this is the case where when some of the subject information has attribute information of a specific attribute, and other portions of the subject information do not have attribute information of the specific attribute, the subject information can be conveniently filtered.

In a preferred embodiment, a keyword for obtaining attribute information of a predetermined attribute in the subject information is searched based on the subject information stored in the information storage unit, and the keyword related to the filter condition is specified based on a selection of a user.

Specifically, the control unit 10 controls the display unit 4 to display a keyword menu item of a keyword query configured to represent attribute information of a predetermined attribute, such as the substation 1203, the device area 1204, and the device type 1205, on the filter condition setting interface illustrated in fig. 12. When the information storage unit stores the subject information as shown in fig. 14, the control unit 10 searches the subject information stored in the information storage unit based on the device type 1205 selected by the user in accordance with the "subject i" shot this time, obtains the keywords "subject i, subject ii, device iii …" of the attribute information of the predetermined attribute (device type), causes the display list 1206 to be displayed, and the user selects "subject i" from among them, and the keyword determination unit determines "subject i" as the keyword related to the filter condition. Here, the display section 4, the operation section 11, and the control section 10 constitute an example of a task setting section; in this embodiment, when the types of keywords of the attribute information of the subject information are large, the operation becomes complicated.

In still another preferred embodiment, the keyword determination unit determines a keyword search condition, searches for a keyword that obtains attribute information of a predetermined attribute in the subject information that matches the keyword search condition based on the subject information stored in the information storage unit, and determines a keyword related to the filter condition based on a user's selection; wherein the keyword query condition is one or more of the keywords related to the filtering condition determined before.

Specifically, when the object information as shown in fig. 14 is stored in the information storage portion, the object information of some other substation is also included, unlike the case of fig. 4. The control unit 10 causes the display unit 4 to display a filter condition setting interface in the setting operation, as shown in the example of fig. 13, and when the user selects the substation 1303 via the operation unit 11, the control unit 10 inquires about keywords of attribute information of attributes of the substation based on the subject information stored in the information storage unit, and causes the list 1306 to be displayed; the user selects "substation 1" from among them, and the control unit 10 determines "substation 1" as a keyword related to the filter condition; then, when the device type 1305 is selected, the control section 10 determines "substation 1" selected by the user as a keyword query condition, and queries a keyword of attribute information that meets the device type attribute of the subject information of "substation 1", so that a list 1307 of "subject i, subject ii, and device iii" is displayed, and the user selects the device type "subject i" from the list; the control unit 10 specifies "the substation 1" and "the object i" as keywords relating to the filtering condition. Obviously, this way, the number of keywords to be selected will be simplified.

A logic determination unit for determining a filtering logic relationship of the keywords related to the filtering condition; the filtering logical relationship may be that when the keyword related to the filtering condition is a keyword, the filtering of the keyword is a non-relationship; when the keywords related to the filtering condition are a plurality of keywords, the keywords are the combination of AND, OR, NOT logical relationship and filtering NOT relationship among the keywords; the logical relationship between the filter non-relationship and the keyword may be a default or may be determined according to user settings.

An example of a keyword, such as a keyword relating to a filtering condition being a keyword "subject i", in fig. 12, the options "yes" 1201 and "no" 1202 of the shooting condition are used to set the filtering non-relation; when yes is selected, the filtering condition generated by combining the keyword 'subject I' is used for subsequent searching and determining subject information meeting the 'subject I' as a shooting task; when 'not' is selected, the filter condition generated in combination with the keyword 'subject i' is used for subsequent search to determine subject information conforming to the 'subject i' that is not. In this case, the logic determination unit determines the filtering non-relationship as "yes" according to the default filtering non-relationship as "yes". When the user specifies the filtering condition through the operation unit 11, the filtering condition generating means (control unit 10) generates the filtering condition by combining the default filtering non-relationship "yes" with the keyword "subject i" selected by the user. At the time of task determination, object information conforming to the keyword "object i" is searched for as determined object information.

Examples of the plurality of keywords such as "substation 1" and "subject i" as the keywords related to the filtering condition, in fig. 13, the logic determination unit determines the filtering non-relationship as "yes" according to the default filtering non-relationship, and determines the logical relationship of the keywords "substation 1" and "subject i" as "and" according to the default logical relationship (the keywords of different attributes are "and" relationship "); when the user specifies the filtering condition through the operation unit 11, the filtering condition generating means (control unit 10) combines the keywords "substation 1" and "subject i" related to the filtering condition with the default logical relationship "and combines the default filtering with the non-relationship" yes "to generate the filtering condition. At the time of task determination, object information conforming to the keyword "substation 1" and conforming to the "object i" will be searched as determined object information.

The generated filter condition is recorded in the temporary storage unit 6 or in the flash memory 9 or the like (for example, a configuration file is generated) for later use.

In step S203, the task determination section determines subject information from the subject information stored in the information storage section, the determined subject information being used to specify the special subject information therefrom, which can be understood as the subject information included in the shooting task.

If "substation 1" and "equipment area 1" are used as the filter conditions, when the information storage section stores the subject information as stored in fig. 14, the subject information that matches the keyword "substation 1" and that matches "subject i" is searched as the determined subject information.

The determined subject information is shown in fig. 15, in which the number of shooting tasks for the other substations, "equipment area 2", and "equipment ii", "equipment iii", is reduced to "6" compared to before the task determination.

Obviously, the shooting path in the specific shooting task is simplified, and the user looks at the information of the equipment area in the shot object indication information, so that the searching work of the equipment I in the equipment area 2 is avoided, and the working strength is reduced.

Further, step S202 is not essential, and the task determination section may determine subject information that meets the filter condition based on a pre-stored filter condition as a default; further, there are embodiments in which the task determination is performed, for example, when a plurality of data files (each including subject information to which a sort order is added) are stored in advance in the flash memory 9 (or the memory card 8), a user is provided to select a data file, and the subject information in the data file selected by the user is determined as the subject information included in the shooting task; further, the object information may be determined based on a user's selection of a plurality of object information.

Step S204 of specifying special subject information; an information specifying unit that specifies subject information as special subject information from the plurality of subject information specified by the task specifying unit.

The control unit 10 controls to designate, as the special object information, the object information "substation 1 equipment area 1 device ic phase" at the top of the added sort order among the plurality of pieces of object information thus determined, and proceeds to step S205.

Step S205, transmitting the thermal image data obtained by shooting by the shooting part 1 to the temporary storage part 6; the image processing part 2 carries out pseudo-color processing on the thermal image data shot by the shooting part 1 to obtain image data of the infrared thermal image, and the image data is stored in the temporary storage part 6.

In step S206, the subject indication information obtained from the special subject information and the infrared thermography are simultaneously displayed on the display 4.

In step S207, the control unit determines whether or not a switching instruction operation is performed, and if not, the steps S205 to S207 are repeated, and if a switching instruction operation is performed, the process proceeds to step S208.

In step S208, the control unit 10 determines whether or not the task is completed.

And if the operation is finished, the information indicates that the shooting in the shooting mode is finished, the thermal image device returns to the standby state, and the user waits for the operation in other modes. If not, the process returns to step S204, and switches the designated special object information based on the sort order added to the object information determined by the task determination unit.

Specifically, in one embodiment, the information specification unit (control unit 10) adds 1 to the serial number of the sorting order corresponding to the specific object information specified before the switching, and then determines whether the last one of the sorting orders is completed, if not, searches for the object information corresponding to the sorting order serial number obtained by adding 1 to the sorting order serial number (among a plurality of object information determined by the task determination unit shown in fig. 15), specifies the searched object information as the specific object information, and if not, continues adding 1 and continuing the search until the searched object information is found; and so on; and when the judgment is finished, ending.

In another embodiment, the determined object information is added with the serial numbers of 1, 2 and 3 … temporarily according to the sequence order, then the serial number of the appointed object information before switching is added with 1, whether the last one of the temporary serial numbers is finished is judged, if not, the corresponding object information after adding 1 to the serial number is searched and designated as the special object information, and if the judgment is finished, the operation is finished. Similarly to embodiment 1, it is not essential to determine whether or not the designation of the last object information is completed.

Returning to step S204, the information specifying unit switches the specified special object information based on the sort order added to the object information specified by the task specifying unit.

Wherein the specified special subject information is switched; in a preferred embodiment, the information specifying unit switches the single object information specified as the special object information from the single object information specified as the special object information before switching to the next object information in the sorting order sequence (the sorting order sequence of the object information specified by the task specifying unit) of the object information specified as the special object information before switching.

Further, the information specifying unit switches the single object information specified as the special object information from the object information specified before switching as the special object information to the object information that is one of the object information specified before switching in the sorting order sequence (the sorting order sequence of the object information determined by the task determining unit). The switching is performed based on the sorting order, which may be the order of the sorting order sequence or the reverse order.

Further, when the information specifying section specifies the subject information as the special subject information as two or more pieces of subject information adjacent in order; the information specifying unit changes the specified specific number of pieces of the object information to be sorted adjacent to each other, which is specified before the change, from the specified specific number of pieces of the object information to be sorted adjacent to each other, which is specified before the change, to the specified specific number of pieces of the object information to be sorted adjacent to each other, which is starting from the next piece of the object information to be specified before the change in the sorting order sequence (the sorting order sequence of the object information specified by the task specifying unit). Further, there may be a case where switching is performed in the reverse order.

In this embodiment, when the user finishes shooting the device i in the device area 1, the user will go to the device i in the shooting device area 3, and the device i in the device area 2 is prevented from being searched, and the shooting path of the device areas 1(1601), 2(1602), 3(1603) in fig. 16 is changed from L10 in fig. 10 to L16 in fig. 16.

In the embodiment, after entering the information mode, task setting is performed; however, it is also possible to perform task setting separately and then enter the information mode, for example, to record the filter condition or the subject information determined based on the filter condition and the sorting order thereof in the information storage unit, for example, to generate a profile for subsequent use. Further, a plurality of task settings may be performed. Further, the filtering condition setting step and the task determining step are set forth in steps, but may be configured to be an immediate progressive process, that is, when one of the filtering conditions is set, the task determining section determines the subject information in accordance with the filtering condition, and when the setting is completed, the task determining section completes the determination of the subject information in accordance with the filtering condition; when the setting is determined, processing proceeds to a specifying step of the special subject information. It is obvious that many more embodiments can be obtained by different combinations.

As described above, by setting the filtering condition of the subject information in the shooting task, the display of redundant information can be reduced, the displayed subject indication information is more instructive, the shooting path is simplified, and the purposes of reducing strength, improving efficiency and avoiding omission are achieved. Obviously, when various filtering conditions are set, great convenience is brought to shooting of a user. If the object information has the attribute information of the history (such as the past defect situation), the user can quickly find the related information of the defect object by inquiring the defect situation, thereby being convenient for the retest.

Example 3

The present invention is applied to the thermal image device 13 having the photographing function in the above-described embodiments, and may also be applied to a thermal image processing device or the like that receives and processes thermal image data from the outside. The present embodiment takes the thermal image processing apparatus 100 as an example of the thermal image capturing apparatus.

In the embodiment, as shown in fig. 18, the thermal image acquisition device 101 is erected on the detection vehicle by using a cradle head and the like, and is connected to the thermal image processing device 100 by using a communication line such as a dedicated cable or a local area network formed in a wired and wireless manner. The user views the subject thermal image through the thermal image processing apparatus 100. And the thermal image acquisition device 101 is connected with the thermal image processing device 100 to form a thermal image shooting system in the embodiment.

Fig. 17 is a block diagram of an electrical structure of one implementation of the thermal image shooting system formed by connecting the thermal image processing device 100 and the thermal image device 101.

The thermal image processing apparatus 100 includes a communication interface 1, an auxiliary storage unit 2, a display control unit 3, a display unit 4, a hard disk 5, a temporary storage unit 6, an operation unit 7, and a CPU8 connected to the above components via a bus and performing overall control. The thermal image processing device 100 may be, for example, a computer or a dedicated processing device. The thermal image processing device 100 receives thermal image data output by the thermal image acquisition device 101 connected with the thermal image processing device 100 through the communication interface 1 based on the control of the CPU 8. The communication interface 1 is used for continuously receiving thermal image data output by the thermal image acquisition device 101; receiving thermal image data (transmitted by the relay device through the thermal image data output by the thermal image acquisition device 101) transmitted by the relay device; meanwhile, the thermal image acquisition device can also be used as a communication interface for controlling the thermal image acquisition device 101. Here, the communication interface 1 may be various wired or wireless communication interfaces on the thermal image processing apparatus 100, such as a network interface, a USB interface, a 1394 interface, a video interface, and the like. The auxiliary storage unit 2 is a storage medium such as a CD-ROM or a memory card, and a related interface. The display control unit 3 displays a display image on the display unit 4 under the control of the CPU 8. The display unit 4 may be a liquid crystal display, or the thermal image processing apparatus 100 may have no display in its own electrical structure. The hard disk 5 stores therein a program for control and various data used in the control. The temporary storage 6, such as a volatile memory, e.g., a RAM, a DRAM, or the like, functions as a buffer memory for temporarily storing thermal image data received by the communication interface 1, and functions as a work memory for the CPU 8. The operation unit 7: for the user to operate. The CPU8 controls the overall operation of the thermal image processing apparatus 100 and performs various related processes. For example, the received thermal image data is subjected to predetermined processing such as correction, interpolation, pseudo color, synthesis, compression, decompression, and the like, and converted into data suitable for display, recording, and the like. For example, when the received thermal image data is compressed thermal image AD data, the predetermined processing, such as the CPU8, decompresses the thermal image data received by the obtaining part and performs corresponding pseudo color processing; for example, when the received thermal image data itself is already image data of a compressed infrared thermal image, the image data of the infrared thermal image is decompressed to obtain image data of the infrared thermal image. For example, when the communication interface 1 receives an analog thermal infrared image, image data of a digital thermal infrared image is obtained after AD conversion by the relevant AD conversion circuit.

The thermal image capturing device 101 includes a communication interface 10, an image capturing unit 20, a flash memory 30, a temporary storage unit 50, an image processing unit 40, and a CPU 60. The CPU60 controls the overall operation of the thermal image acquisition device 101, and the flash memory 30 stores a control program and various data used for controlling each part. The photographing part 20 is used for photographing to obtain thermal image data, the temporary storage part 50 is used for temporarily storing processed data, the image processing part 40 is used for compressing the photographed thermal image data and the like, and the CPU60 controls the processed thermal image data to be output through the communication interface 10.

The structure of the thermal image device 13 excluding the photographing part 1 is substantially the same as that of the thermal image processing device 100, and it is obvious that the present embodiment is equally applicable by acquiring thermal image data received from the outside. Therefore, the description of the embodiments is omitted. Obviously, the thermal image processing device 100 can be used with various thermal image acquisition devices having a thermal image shooting function, such as various handheld thermal image devices.

Preferably, the shot indication information and the continuous infrared thermal images are displayed simultaneously; for example, when a display instruction of predetermined specially displayed subject instruction information is received, the subject instruction information and the frozen infrared thermal image may be displayed simultaneously; in addition, the display control unit may switch the display infrared thermal image to display the object indication information obtained according to the special object information specified by the information specifying unit in a special display manner in response to the display indication of the object information (for example, pressing a key representing the object information display); and then, switching operation can be carried out, the indication information of the shot object after switching is particularly displayed, and when the display indication of the infrared thermal image is responded, the infrared thermal image is displayed. After the special display, the display may be blanked after a predetermined time or based on a user operation to avoid occupation of the display screen. Further, the user may select the plurality of pieces of subject instruction information displayed in the sorted order without performing the switching operation, and the information specifying unit may specify the subject information as the special subject information based on the selection by the user; in this way, since the subject instruction information is displayed in the order of the order added to the subject information, the user can select the subject instruction information easily and clearly, and the present invention is also configured. In addition, the invention is also suitable for the thermal image shooting device of static imaging.

In the above embodiments, the subject application in the power industry is exemplified as a scene, but the present invention is also applicable to various industrial applications of infrared detection.

In addition, the processing and control functions of some or all of the components in embodiments of the present invention may also be implemented using dedicated circuits or general purpose processors or programmable FPGAs. Although the functional blocks in the drawings may be implemented by hardware, software, or a combination thereof, there is generally no need for structures to implement the functional blocks in a one-to-one correspondence; for example, a functional block may be implemented by one software or hardware unit, or a functional block may be implemented by multiple software or hardware units.

The foregoing describes only embodiments of the invention and is presented by way of illustration rather than limitation, and further modifications and variations of the embodiments may be made by persons skilled in the art in light of the foregoing description without departing from the spirit or scope of the invention.
