Description

分析装置和分析方法Analysis device and analysis method 技术领域Technical field
本发明的分析装置和分析方法,涉及热像分析的应用领域。The analysis device and analysis method of the present invention relate to the field of application of thermal image analysis.
背景技术Background technique
在热像分析时，为获得对被摄体热像的分析数据和诊断结果，目前，需要人工对热像数据帧设置分析区域、分析模式、诊断规则，分析区域例如点、线、面等一个或多个区域的组合，对应被摄体热像需要分析的部位；分析模式，例如分析区域对应的分析计算规则，如计算最高温度、平均温度、最低温度、百分比含量等，以及还可包括分析区域之间的计算关系如温差等；诊断规则，例如与分析区域和分析模式，相对应的比较关系及阈值等。In the thermal image analysis, in order to obtain the analysis data and diagnosis results of the thermal image of the subject, at present, it is necessary to manually set an analysis area, an analysis mode, a diagnosis rule, and an analysis area such as a point, a line, a surface, and the like for the thermal image data frame. Or a combination of multiple regions, corresponding to the part of the subject's thermal image that needs to be analyzed; an analysis mode, such as an analysis calculation rule corresponding to the analysis region, such as calculating a maximum temperature, an average temperature, a minimum temperature, a percentage content, etc., and may also include analysis Calculation relationships between regions such as temperature differences; diagnostic rules, such as comparisons and thresholds corresponding to analysis regions and analysis modes.
分析区域、分析模式、诊断规则的设置，当由人工完成，操作非常繁琐；目前的操作步骤一般是先选择分析区域的构成数据，例如点、线、面；而后，将分析区域设置在红外热像中，并调整分析区域位于红外热像中的位置参数；如设置多个分析区域时，将设置操作多次。而后，根据分析区域的编号，来输入分析模式；而后根据分析模式，来编排诊断规则。The analysis area, analysis mode, and diagnostic rule settings are very cumbersome when done manually; the current operation steps generally select the constituent data of the analysis area, such as points, lines, and faces; then, set the analysis area to infrared heat. In the image, and adjust the position parameter of the analysis area in the infrared thermal image; if multiple analysis areas are set, the operation will be set multiple times. Then, according to the number of the analysis area, the analysis mode is input; and then the diagnosis rule is arranged according to the analysis mode.
人工设置分析区域、分析模式、诊断规则的操作，技术要求非常高；因为对于被摄体热像，分析区域对应的部位、应用的分析模式、诊断规则等都有非常严格的要求，需要使用者对被摄体热像分析具有非常强的专业性；例如，在电力行业，根据电力行业规范的规定，各种被摄体例如开关、避雷器、电缆终端等均有特定分析的部位及特定的分析模式、诊断规则，以电缆终端的分析为例，其中需要对其本体套管的上部和下部的规定部位，设置分析区域，而后，来计算各自的最高温度、及相互之间的温差；如果分析区域没有精确地设置在上述部位，或分析模式设置不合理，则无法获得正确的分析数据。而设置诊断规则，则需要使用者对被摄体的诊断依据等非常精通，要求非常高。而电力行业涉及的需要红外检测的被摄体种类达几十种，根据不同的电压等级来分，可能达上千个类型，可想其中的技术难度。Manually setting the analysis area, analysis mode, and diagnostic rules, the technical requirements are very high; because the thermal image of the subject, the corresponding part of the analysis area, the analysis mode of the application, and the diagnostic rules have very strict requirements, requiring users. It has a very strong professionalism in the thermal image analysis of the subject; for example, in the power industry, according to the regulations of the power industry, various subjects such as switches, arresters, cable terminals, etc. have specific analysis parts and specific analysis. Modes, diagnostic rules, taking the analysis of cable terminations as an example, where the upper and lower parts of the body casing need to be set up, and then the analysis area is set, and then the maximum temperature and the temperature difference between each other are calculated; If the area is not accurately set at the above location, or the analysis mode setting is unreasonable, the correct analysis data cannot be obtained. Setting the diagnostic rules requires the user to be very proficient in the diagnosis of the subject, and the requirements are very high. The power industry involves dozens of types of subjects that require infrared detection. Depending on the voltage level, there may be thousands of types, and the technical difficulty can be considered.
并且，在进一步深入的应用中，分析区域的尺寸等也有严格的要求，因为不同尺寸的分析区域，即便设置在相同的部位，其分析结果也可能不同，例如设置的太小，有可能遗漏了关键的部位范围，如设置的太大，则有可能导致容易受干扰因素影响。Moreover, in further in-depth applications, the size of the analysis area and the like are also strictly required, because the analysis areas of different sizes, even if they are placed in the same part, the analysis results may be different, for example, the setting is too small, and may be missed. The critical part range, if set too large, may be susceptible to interference.
在更为深入的应用中，还对分析区域的编号，有规范的要求，否则，同类被摄体的相同部位，如果设置了不同编号的分析区域，即便各自的分析模式、诊断规则是正确的，后续仍很难进行相互之间的对比。In more in-depth applications, there are also specifications for the number of analysis areas. Otherwise, if the same part of the same type of object is set with different numbered analysis areas, even if the respective analysis mode and diagnostic rules are correct. It is still difficult to compare them with each other.
而对于很多类型的被摄体拍摄获得的被摄体热像而言，如要追求精细的分析结果，需要设置较多的分析区域和更为复杂的分析模式、诊断规则，这时，操作极为繁琐易错。For the thermal image of the subject obtained by many types of subjects, if you want to pursue detailed analysis results, you need to set more analysis areas and more complicated analysis modes and diagnostic rules. It is cumbersome and error-prone.
此外，即便是非常有经验的使用者，由于拍摄的热像并不一定能满足分析的要求，这时，即便进行了细致的设置，也未必能获得满意的分析结果。目前，对于很多用户，由于拍摄时设置操作过于繁琐和技术性太强，因此热像的拍摄工作和分析区域、分析模式、诊断规则的后续设置工作，往往由不同的人员完成，也加剧了这种情况。In addition, even a very experienced user, because the thermal image taken does not necessarily meet the requirements of the analysis, even if the detailed settings are made, it may not be possible to obtain satisfactory analysis results. At present, for many users, because the setting operation is too cumbersome and technically strong during shooting, the shooting work of the thermal image and the subsequent setting work of the analysis area, analysis mode, and diagnostic rules are often completed by different personnel, which also aggravates this Happening.
综上，现有技术需要人工设置被摄体热像对应的分析区域、分析模式、诊断规则，需要依赖使用者的主观经验，其弊端可总结为操作繁琐、技术难度大等。In summary, the prior art requires manual setting of the analysis area, analysis mode, and diagnostic rule corresponding to the thermal image of the subject, and relies on the subjective experience of the user, and the drawbacks can be summarized as cumbersome operation and technical difficulty.
因此，所理解需要一种热像诊断装置，其能达到无需过度依赖使用者主观上的意念，能方便地设置分析区域、分析模式、诊断规则其中之一或多个，解决现有技术问题的部分或全部问题。 Therefore, it is understood that there is a need for a thermal imaging diagnostic apparatus that can easily set one or more of an analysis area, an analysis mode, and a diagnosis rule without excessively relying on the user's subjective idea, and solve the prior art problem. Some or all of the questions.

For example, the position data of the analysis area is set according to the detected position and size of the specific subject thermal image, but is configured according to the default analysis area composition data, analysis mode, and diagnostic rule; when analyzing the area, analyzing the mode, and diagnosing The rules are not all determined by the detected regulatory information, but are also superior to the prior art.
分析区域设置单元，根据分析配置单元配置的分析区域的构成数据和位置参数，对热像数据帧设置分析区域。The analysis area setting unit sets an analysis area for the thermal image data frame according to the composition data and the position parameter of the analysis area configured by the analysis configuration unit.
分析单元，根据分析区域设置单元设置的分析区域，分析配置单元设置的分析模式，进行热像数据帧的分析，以温度分析为例来说明分析单元的具体实施方式。The analyzing unit analyzes the analysis mode set by the configuration unit according to the analysis area set by the analysis area setting unit, analyzes the thermal image data frame, and illustrates the specific implementation manner of the analysis unit by taking temperature analysis as an example.
一种实施方式，基于控制部11的控制，分析单元对所分析的热像数据帧或进行规定处理如修正、插值的热像数据帧，基于分析区域设置单元所设置的分析区域，提取分析区域所决定的热像数据，进行温度值的转换处理，获得这些热像数据对应的温度值，而后对得到的温度值，按照分析模式进行分析计算。例如计算其中最大值，则提取其中最大的温度值作为分析结果。当分析区域包含多个分析区域单元时，如图6(b)所示，分析区域F1有分析区域单元S01、S02，则依次对各分析区域单元中的热像数据，进行温度值的转换和进行分析，获得各区域单元的分析结果，将计算获得的分析结果与分析区域单元的编号关联存储在临时存储部6的规定区域，而后根据各分析区域单元的分析结果，按照分析模式中各分析区域单元的相互关系，来计算获得相互关系的分析结果。According to an embodiment, based on the control of the control unit 11, the analyzing unit extracts the analysis area from the analyzed thermal image data frame or the thermal image data frame subjected to predetermined processing such as correction and interpolation, based on the analysis area set by the analysis area setting unit. The determined thermal image data is subjected to temperature value conversion processing to obtain temperature values corresponding to the thermal image data, and then the obtained temperature values are analyzed and calculated according to the analysis mode. For example, if the maximum value is calculated, the largest temperature value among them is extracted as the analysis result. When the analysis area includes a plurality of analysis area units, as shown in FIG. 6(b), the analysis area F1 has analysis area units S01 and S02, and sequentially converts the temperature values of the thermal image data in each analysis area unit. Perform analysis to obtain the analysis result of each regional unit, store the calculated analysis result in association with the number of the analysis area unit in a predetermined area of the temporary storage unit 6, and then analyze each analysis according to the analysis result of each analysis area unit. The relationship between the regional units is used to calculate the analysis results of the mutual relationship.
上述的例举并非作为分析处理的实施方式的限定。例如，对分析区域中的热像数据进行转换为温度值的处理，可以是将分析区域中所有的热像数据都转换为温度值；也可以是规定的部分热像数据转换为温度值；还可以是根据分析模式中计算最高、最低、平均温度等不同的模式，来决定对热像数据的转换，是转换分析区域中的一部分热像数据，还是全部；如分析模式为计算分析区域中最高温度时，也可针对分析区域中的热像数据，先比较热像AD值的 大小，将其中最大的热像AD值转换为温度值，而并不必须将分析区域中的热像数据全部转化为温度值。此外，也包括算法不同的情况，例如计算最高温度时，并不以单个像素而是以规定数量的相邻像素的AD值的平均值，将最大平均值的相邻像素的AD值转换为温度值，并将该相邻像素热像数据的温度值的平均值作为最高温度值。其中，热像数据经过规定处理转换为温度值，例如根据设置的被摄体的辐射系数、环境温度、湿度、与热像装置13的距离等以及热像AD值与温度之间的转换系数，通过规定转换公式，得到温度值。此外，分析区域所决定的热像数据，如图6(b)所示，可以是分析区域单元S01、S02内的热像数据，也可以是分析单元S01、S02外的热像数据，也可以是分析区域单元S01、S02的线条所在像素的热像数据。The above examples are not intended to be limiting as to the embodiment of the analysis process. For example, the process of converting the thermal image data in the analysis region into a temperature value may be to convert all the thermal image data in the analysis region into a temperature value; or to convert the predetermined partial thermal image data into a temperature value; It is possible to determine the conversion of the thermal image data according to the different modes of calculating the highest, lowest, and average temperatures in the analysis mode, whether to convert part of the thermal image data in the analysis region, or all; for example, the analysis mode is the highest in the calculation analysis region. At the temperature, the thermal image AD value can also be compared for the thermal image data in the analysis area. The size, the largest thermal image AD value is converted into a temperature value, and it is not necessary to convert all the thermal image data in the analysis area into a temperature value. In addition, the case where the algorithm is different is also included. For example, when calculating the highest temperature, the AD value of the adjacent pixel of the maximum average value is not converted into the temperature by the average value of the AD values of the predetermined number of adjacent pixels instead of a single pixel. A value and an average value of temperature values of the adjacent pixel thermal image data is taken as the highest temperature value. Wherein the thermal image data is converted into a temperature value by a predetermined process, for example, according to the set emissivity of the object, the ambient temperature, the humidity, the distance from the thermal image device 13, and the conversion coefficient between the thermal image AD value and the temperature, The temperature value is obtained by specifying a conversion formula. Further, as shown in FIG. 6(b), the thermal image data determined by the analysis area may be thermal image data in the analysis area units S01 and S02, or may be thermal image data outside the analysis units S01 and S02. It is the thermal image data of the pixel in which the lines of the area units S01 and S02 are analyzed.
上面的示例说明的根据分析区域来获得温度分析结果的情况，但不限与此，对于热像分析根据应用场合的不同，并不一定是将热像数据转换为温度值来进行的，例如，可以转换为辐射能量值、灰度值、辐射率值等进行分析的情况。本发明同样适用于这些情况。The above example illustrates the case where the temperature analysis result is obtained according to the analysis area, but is not limited thereto. For the thermal image analysis, depending on the application, it is not necessarily the conversion of the thermal image data into the temperature value, for example, It can be converted into a radiant energy value, a gray value, an illuminance value, and the like for analysis. The invention is equally applicable to these situations.

判断单元，将相关度的值，根据规定的判断值进行判断，来确定是否检测到特定被摄体热像；例如，当代表与模板图像之间的类似程度的相关度的值，超过了判断值时，将该帧判断为包含有特定被摄体热像的帧，即检测到特定被摄体热像。The judging unit determines whether the value of the correlation degree is determined according to the predetermined judgment value to determine whether a specific subject thermal image is detected; for example, when the value representing the degree of similarity between the representative image and the template image exceeds the judgment In the case of a value, the frame is determined to be a frame including a specific subject thermal image, that is, a specific subject thermal image is detected.
检测部8的检测处理可以是基于模板匹配的检测方式，基于检测窗口中的热像数据与模板图像进行相关度的计算和比较；例如，计算检测窗口中的红外热像和作为模板的红外热像相互对应的位置的像素之间的差的和，所计算出的差的和越小，相关度越高。其中，模板匹配的处理，也可配置为提取特征量进行匹配的实施方式，利用模板图像的特征量与检测窗口中的热像数据的特征量，二者之间的比较来确定相关度。例如，提取检测窗口中的被摄体图像的特定像素的比例，与模板图像中的特定像素的比例越接近，所计算出的差越小，相关度越高。The detection processing of the detecting portion 8 may be based on a template matching detection method, and performs correlation calculation and comparison based on the thermal image data in the detection window and the template image; for example, calculating an infrared thermal image in the detection window and infrared heat as a template The sum of the differences between the pixels of the positions corresponding to each other, the smaller the sum of the calculated differences, the higher the correlation. The processing of the template matching may also be configured to extract the feature quantity for matching, and use the comparison between the feature quantity of the template image and the feature quantity of the thermal image data in the detection window to determine the correlation. For example, the closer the ratio of the specific pixel of the subject image in the detection window is extracted to the specific pixel in the template image, the smaller the calculated difference is, and the higher the correlation is.
检测部8的检测处理，基于参数描述的特征量的检测实施方式。例如，可根据被摄体识别信息计算获得检测窗口中热像数据的特征量，作为相关度的值；例如，被摄体识别信息还可包含特征量基准值，可进行规定的运算来获得检测窗口中的热像数据的特征量，并与特征量基准值进行比较，来获得相关度的值；在一例中，所述特征量基准值为特定像素值的规定像素比例，检测单元计算热像数据中特定像素值的像素比例，二者进行比较，来获得相关度的值，所计算出的差越小，相关度越高。将相关度的值，与判断值进行比较，来确定是否检测到特定被摄体热像。The detection processing of the detecting unit 8 is based on the detection method of the feature amount described by the parameter. For example, the feature amount of the thermal image data in the detection window may be calculated as the value of the correlation degree according to the subject identification information; for example, the subject identification information may further include a feature amount reference value, and a predetermined operation may be performed to obtain the detection. a feature quantity of the thermal image data in the window, and comparing with the feature quantity reference value to obtain a value of the correlation degree; in one example, the feature quantity reference value is a prescribed pixel ratio of a specific pixel value, and the detecting unit calculates the thermal image The pixel ratio of a specific pixel value in the data is compared to obtain the value of the correlation, and the smaller the calculated difference is, the higher the correlation is. The value of the correlation is compared with the judgment value to determine whether a specific subject thermal image is detected.
优选的方式，采用轮廓图像作为匹配的模板图像，检测部8例如通过以下的处理来检测热像数据帧中是否具有特定被摄体；首先，检测部8提取位于检测窗口中的热像数据，按照AD值的预定阀值对读取的检测窗口中的热像数据进行二值化；接着，提取该二值图像的具有预定像素值(1或0)的像素相连通的连通图像；而后判断该连通图像是否具有预定范围的大小；如果判断出该连通图像的大小在预定范围内，则近一步在提取的连通图像与所登记的模板图像之间执行比较处理，例如计算二者之间的重叠面积在各自总面积中的比例之和，获得相关度的值；该数值越大，则相关度越高；将相关度的值，根据规定的判断值进行判断，来确定是否检测到特定被摄体热像。In a preferred embodiment, the contour image is used as the matched template image, and the detecting unit 8 detects whether or not there is a specific subject in the thermal image data frame, for example, by the following processing; first, the detecting unit 8 extracts the thermal image data located in the detection window, And normalizing the thermal image data in the read detection window according to a predetermined threshold of the AD value; then, extracting the connected image of the binary image having the predetermined pixel value (1 or 0) connected; and then determining Whether the connected image has a predetermined range of size; if it is determined that the size of the connected image is within a predetermined range, a comparison process is performed between the extracted connected image and the registered template image, for example, between the two The sum of the ratios of the overlapping areas in the respective total areas obtains the value of the correlation; the larger the value, the higher the correlation; the value of the correlation is judged according to the specified judgment value to determine whether a specific one is detected Thermal image of the subject.
对于检测的示例，如图5所示，检测部8从热像数据帧501的规定检测区域G1的左上角到右下角移动窗口J1以进行检测，剪切窗口中的热像数据，并检测其与模板图像T1的相关度。具体而言，窗口J1从左端向右以规定值的窗口位移(例如一个像素)逐步地移动，并在到达右端后，被设置返回左端并向下移动窗口位移，以及随后再次逐步地向右移动。为高精度地检测被摄体，检测的窗口尺寸、窗口位移、窗口的倾斜角度的变换范围被预先定义，例如窗口尺寸的变化范围从150×50像素到120×40像素，窗口位移的变化范围从10个像素到1个像素，窗口的倾斜角度的变化范围为基于中心点的0°到10°。检测部8逐次的，每 次5个像素地改变窗口尺寸，并每次1个像素地改变窗口位移，并每次2°地改变窗口倾斜角度。检测部8进行模板图像T1和热像数据帧501的相关度计算；在完成所有检测窗口的检测后，从中选择相关度最高的检测窗口所获得的相关度的值，作为该热像数据帧501对应的相关度的值。For the example of detection, as shown in FIG. 5, the detecting section 8 moves the window J1 from the upper left corner to the lower right corner of the predetermined detection area G1 of the thermal image data frame 501 to detect, cuts the thermal image data in the window, and detects it. The degree of correlation with the template image T1. Specifically, the window J1 is gradually moved from the left end to the right with a window displacement of a prescribed value (for example, one pixel), and after reaching the right end, is set to return to the left end and move the window displacement downward, and then gradually move to the right again. . In order to detect the subject with high precision, the range of the detected window size, window displacement, and tilt angle of the window is defined in advance, for example, the window size varies from 150×50 pixels to 120×40 pixels, and the range of window displacement varies. From 10 pixels to 1 pixel, the tilt angle of the window varies from 0° to 10° based on the center point. Detection unit 8 successively, each The window size is changed 5 pixels later, and the window displacement is changed 1 pixel at a time, and the window tilt angle is changed 2° each time. The detecting unit 8 performs correlation calculation of the template image T1 and the thermal image data frame 501; after completing the detection of all the detection windows, the value of the correlation obtained by selecting the detection window with the highest correlation is selected as the thermal image data frame 501. The value of the corresponding relevance.
注意，可以基于被摄体识别信息，来计算相关度的各种方法，上述例举的处理仅是可使用方法的示例。Note that various methods of calculating the degree of correlation may be calculated based on the subject identification information, and the above-exemplified processing is only an example of a usable method.

It can also be converted according to the specified comparison table of the value and the percentage of the correlation degree; other methods such as directly displaying the value of the correlation obtained by the detection processing calculation, and in one example, directly displaying the sum of the differences of the pixel values Values, etc. For convenience of explanation, in the following, the percentage value converted into the correlation value, the evaluation value, and the like is taken as an example, but in practice, it is not necessary to convert into a percentage value.
控制部11控制了热像装置100的整体的动作，在存储介质例如闪存3中存储有用于控制的程序，以及各部分控制中使用的各种数据。控制部11例如由CPU、MPU、SOC、可编程的FPGA等来实现。The control unit 11 controls the overall operation of the thermal imaging device 100, and stores a program for control and various data used for control of each part in a storage medium such as the flash memory 3. The control unit 11 is realized by, for example, a CPU, an MPU, an SOC, a programmable FPGA, or the like.
在本实施例中，控制部11作为选择部的例子，用于选择被摄体信息；例如根据使用者对被摄体指示信息的选择，来选择所述被摄体指示信息对应的被摄体信息。In the present embodiment, the control unit 11 is used as an example of the selection unit for selecting subject information; for example, the subject corresponding to the subject instruction information is selected according to the user's selection of the subject instruction information. information.
操作部12：用于使用者进行各种指示操作，或者输入设定信息等各种操作，控制部11根据操作部12的操作信号，执行相应的程序。参考图2来说明操作部12，提供使用者操作的按键有记录键01、调焦键02、确认键03、回放键04、菜单健05、方向键06等；此外，也可采用触摸屏07或语音识别部件(未图示)等来实现相关的操作。The operation unit 12 is for the user to perform various instruction operations or input various operations such as setting information, and the control unit 11 executes the corresponding program based on the operation signal of the operation unit 12. Referring to FIG. 2, the operation unit 12 is provided. The buttons for providing user operations include a record button 01, a focus button 02, a confirmation button 03, a play button 04, a menu button 05, a direction button 06, and the like; in addition, a touch screen 07 or a touch screen can be used. A speech recognition component (not shown) or the like is used to implement related operations.
参考图6来说明拍摄过程中的显示界面的变化，参见图7来说明热像装置100的检测模式的控制流程，本应用场景如使用者手持热像装置100对变电站的被摄体进行拍摄。在接通电源后，控制部11进行内部电路的初始化，而后，进入拍摄模式，即拍摄部1拍摄获得热像数据帧，图像处理部7将拍摄部1拍摄获得的热像数据帧进行规定的处理，存储在临时存储部2中，显示部10上以动态图像形式连续显示红外热像，在此状态，控制部11实施其控制， 持续监视是否按照预定操作切换到了其他模式的处理或进行了关机操作，如果有，则进入相应的处理控制。检测模式的控制步骤如下：The change of the display interface during photographing will be described with reference to FIG. 6. Referring to FIG. 7, the control flow of the detection mode of the thermal image device 100 will be described. In this application scenario, the user holds the thermal image device 100 to photograph the subject of the substation. After the power is turned on, the control unit 11 initializes the internal circuit, and then enters the imaging mode, that is, the imaging unit 1 captures a thermal image data frame, and the image processing unit 7 defines the thermal image data frame captured by the imaging unit 1. The processing is stored in the temporary storage unit 2, and the infrared thermal image is continuously displayed in the form of a moving image on the display unit 10. In this state, the control unit 11 performs its control. Continuously monitor whether the process of switching to another mode or the shutdown operation is performed according to a predetermined operation, and if so, the corresponding process control is entered. The control mode of the detection mode is as follows:
在步骤A01，特征登记单元登记被摄体识别信息。例如，控制部11基于闪存3中存储的表，将被摄体信息生成的被摄体指示信息显示在显示部10，当使用者根据拍摄现场的被摄体“被摄体1”，通过操作部12来选择显示部10上所显示的“被摄体1”，根据“被摄体1”关联的被摄体识别信息，特征登记单元确定用于检测处理的被摄体识别信息，从闪存3中读取模板图像301，传送到临时存储部2。In step A01, the feature registration unit registers the subject identification information. For example, the control unit 11 displays the subject instruction information generated by the subject information on the display unit 10 based on the table stored in the flash memory 3, and the user operates by the subject "subject 1" at the shooting scene. The portion 12 selects "subject 1" displayed on the display portion 10, and the feature registration unit determines the subject identification information for the detection processing based on the subject identification information associated with the "subject 1", from the flash memory The template image 301 is read in 3 and transmitted to the temporary storage unit 2.
步骤A02，获取热像数据帧，将拍摄部1拍摄获得的热像数据帧传送到临时存储部2；Step A02, the thermal image data frame is acquired, and the thermal image data frame obtained by the imaging unit 1 is transmitted to the temporary storage unit 2;
步骤A03，读取临时存储部2中例如由拍摄部1即时拍摄获得的热像数据帧，检测窗口设置单元，设置检测窗口。例如，基于规定的检测区域G1的左上角，首先设置了检测窗口；In step A03, the thermal image data frame obtained by the image capturing unit 1 for example, for example, is detected in the temporary storage unit 2, the detection window setting unit is set, and the detection window is set. For example, based on the upper left corner of the prescribed detection area G1, a detection window is first set;
步骤A04，对检测窗口中的热像数据，基于被摄体识别信息，进行相关度计算的处理。In step A04, the processing of the correlation calculation is performed based on the subject identification information on the thermal image data in the detection window.
检测部8基于检测窗口设置单元所设置的检测窗口，抽取位于该检测窗口中的热像数据，根据特征登记单元所登记的模板，计算二者之间的相关度。例如，根据检测窗口中的热像数据，提取的特定被摄体热像的轮廓，与轮廓图像T1(模板图像301获得)的轮廓对比，计算二者之间的重叠面积在各自总面积中的比例之和。The detecting unit 8 extracts the thermal image data located in the detection window based on the detection window set by the detection window setting unit, and calculates the correlation between the two based on the template registered by the feature registration unit. For example, according to the thermal image data in the detection window, the contour of the extracted specific subject thermal image is compared with the contour of the contour image T1 (obtained by the template image 301), and the overlapping area between the two is calculated in the respective total areas. The sum of the ratios.
并且，在步骤A05，存储所得到的相关度的值。And, in step A05, the value of the obtained correlation is stored.
在步骤A06中，检测部8判断在热像数据帧中设置检测窗口时，是否已经针对所有检测窗口计算了相关度。如果剩余还没有计算相关度的区域(步骤A06中为否)则回到步骤A03中，检测窗口设置单元在预定方向上将检测窗口的位置偏移预定像素数，将该位置设置为检测窗口的下一位置，并重复后续的处理。In step A06, the detecting section 8 judges whether or not the correlation degree has been calculated for all the detection windows when the detection window is set in the thermal image data frame. If there is no area where the correlation has not been calculated yet (NO in step A06), the process returns to step A03, and the detection window setting unit shifts the position of the detection window by a predetermined number of pixels in a predetermined direction, and sets the position as the detection window. Next position and repeat the subsequent processing.
此外，从热像数据帧中搜索与模板类似的部分时，对于放大及缩小、以及将检测窗口倾斜规定角度后的检测窗口时，也进行类似上述说明的检测处理。Further, when searching for a portion similar to the template from the thermal image data frame, the detection processing similar to that described above is also performed when the detection window is enlarged and reduced and the detection window is tilted by a predetermined angle.
如果已经针对要在热像数据帧中设置的所有检测窗口计算了相关度(步骤A06中为是)，则在步骤A07中获得检测到的最大相关度的值及所对应的检测窗口的位置参数。If the correlation has been calculated for all the detection windows to be set in the thermal image data frame (YES in step A06), the value of the detected maximum correlation and the position parameter of the corresponding detection window are obtained in step A07. .
并且，在步骤A08，如果相关度小于规定的判断值，则检测部8判断没有检测到特定被摄体热像，到步骤A10，如图6(a)所示，由于未在检测区域G1中检测到匹配的被摄体热像，则没有分析、诊断等处理。当在步骤A08检测到的相关度大于规定的判断值，则进入步骤A09。Further, in step A08, if the correlation degree is smaller than the predetermined determination value, the detecting unit 8 determines that the specific subject thermal image is not detected, and proceeds to step A10, as shown in FIG. 6(a), because it is not in the detection area G1. If a matching subject thermal image is detected, there is no processing such as analysis or diagnosis. When the correlation detected in step A08 is greater than the predetermined determination value, the process proceeds to step A09.
步骤A09，在检测到具有特定被摄体热像的热像数据帧后，分析部6，对该热像数据帧进行热像诊断，获得诊断结果。In step A09, after detecting the thermal image data frame having the specific subject thermal image, the analyzing unit 6 performs thermal imaging diagnosis on the thermal image data frame to obtain a diagnosis result.
例如根据相关度最大的检测窗口B1的位置、尺寸来设置分析区域，如图6(b)所示的分析区域F1，并按照分析区域F1对应的分析模式1进行分析，而后进行诊断。For example, the analysis area is set based on the position and size of the detection window B1 having the highest correlation, and the analysis area F1 shown in FIG. 6(b) is analyzed in accordance with the analysis mode 1 corresponding to the analysis area F1, and then the diagnosis is performed.
在检测到具有特定被摄体热像的热像数据帧后，分析配置单元进行分析区域的配置；具体而言，如根据与模板301关联存储的分析区域的构成数据(f1构成数据)，来确定分析区域的构成数据；根据分析区域F1与模板301的规定位置关系，检测窗口B1位于该热像数据帧中的位置、尺寸、倾斜角度，来作为分析区域的位置参数相关的配置信息；并且，可根据图3中的对应关系，配置分析模式1、诊断规则1作为分析模式、诊断规则。在另一例中，也可根据分析区域F1与模板301的规定位置关系，检测窗口B1位于该热像数据帧中的位置、尺寸、倾斜角度，计算获得分析区域位于热像数据帧中的位置参数，而后对分析区域的构成 数据进行相应的缩放等处理，所获得的分析区域的构成数据和分析区域的位置参数，来作为的配置信息。After detecting the thermal image data frame having the specific subject thermal image, the analysis configuration unit performs the configuration of the analysis region; specifically, according to the constituent data of the analysis region stored in association with the template 301 (f1 constitutes data), Determining the composition data of the analysis area; according to the specified positional relationship between the analysis area F1 and the template 301, detecting the position, size, and inclination angle of the window B1 in the thermal image data frame as the configuration information related to the position parameter of the analysis area; According to the correspondence in FIG. 3, the analysis mode 1 and the diagnosis rule 1 can be configured as the analysis mode and the diagnosis rule. In another example, according to the specified positional relationship between the analysis area F1 and the template 301, the position, size, and inclination angle of the window B1 in the thermal image data frame are detected, and the positional parameter of the analysis area located in the thermal image data frame is calculated. And then the composition of the analysis area The data is subjected to corresponding scaling and the like, and the obtained constituent data of the analysis region and the positional parameters of the analysis region are used as configuration information.
此外，所检测到的特定被摄体热像的位置、尺寸、倾斜角度等的位置参数，并不限定于检测窗口的位置参数，例如，进一步提取检测窗口中的热像数据的特征，例如提取被摄体轮廓，来获得更为精确的位置参数，可根据该位置参数来设置分析区域。Further, the detected positional parameters of the position, size, inclination angle, and the like of the specific subject thermal image are not limited to the positional parameters of the detection window, for example, further extracting features of the thermal image data in the detection window, for example, extraction The subject contour is used to obtain a more accurate positional parameter, and the analysis area can be set according to the positional parameter.
分析区域设置单元，根据分析区域的配置信息，例如进行计算位置参数、相应的缩放等处理后，对该热像数据帧设置分析区域F1，包括分析区域S01、S02；The analysis area setting unit sets the analysis area F1, including the analysis areas S01 and S02, to the thermal image data frame according to the configuration information of the analysis area, for example, the calculation of the position parameter, the corresponding scaling, and the like;
而后，分析单元，根据分析区域设置单元设置的分析区域F1，及对应的分析模式1进行分析，获得分析结果；诊断单元，根据分析结果，与分析区域F1和分析模式1对应的“诊断规则1”，来获得诊断结果。如图6(b)所示的分析区域F1，分析结果、诊断结果的显示栏，其中，根据S01和S02最高温度的差值为3℃，小于4℃，大于2℃；诊断结论及注释：关注。注意，分析区域F1、分析结果、诊断结果并不必须显示。Then, the analysis unit analyzes according to the analysis area F1 set by the analysis area setting unit and the corresponding analysis mode 1, and obtains the analysis result; the diagnosis unit, according to the analysis result, the diagnosis rule 1 corresponding to the analysis area F1 and the analysis mode 1 ", to get the diagnosis. As shown in Fig. 6(b), the analysis area F1, the analysis result and the display column of the diagnosis result, wherein the difference between the highest temperature of S01 and S02 is 3 ° C, less than 4 ° C, and more than 2 ° C; diagnosis conclusion and comment: attention. Note that the analysis area F1, the analysis result, and the diagnosis result do not have to be displayed.
后续，可进行诊断结果的通知，通知的方式，控制显示部10将诊断结果等进行显示。并伴随着例如通过显示部10等中以文字或图像(包括红外热像、参考图像等)的显示画面的变化，热像装置100中的指示灯产生的光、扬声器发出的声音提示、振动部件的振动等，只要是使用者可以感知的方法都包含在内。此外，也可输出分析和/或诊断结果，例如从通信接口I/F4输出，被与热像装置100连接的其他外部装置所接收。Subsequently, the diagnosis result can be notified, and the notification display unit 10 displays the diagnosis result and the like. With the change of the display screen of characters or images (including infrared thermal images, reference images, etc.) in the display unit 10 or the like, the light generated by the indicator light in the thermal image device 100, the sound prompt from the speaker, and the vibration component are accompanied by changes. Vibrations, etc., are included as long as they are perceptible by the user. In addition, analysis and/or diagnostic results may also be output, such as output from communication interface I/F 4, received by other external devices connected to thermal imaging device 100.
步骤A10，判断是否退出，如退出，则结束，如未退出，则回到步骤A02，重复上述的处理。这样，对连续拍摄获得的热像数据帧，当检测到相关度高于规定的判断值的热像数据帧时，能根据检测到的被摄体热像，来自动配置分析区域、分析模式、诊断规则，进行相应的处理。In step A10, it is judged whether to exit, if it is exited, it ends. If it is not exited, it returns to step A02, and the above processing is repeated. In this way, when the thermal image data frame obtained by the continuous shooting is detected, when the thermal image data frame whose correlation is higher than the predetermined judgment value is detected, the analysis region, the analysis mode, and the analysis mode can be automatically configured according to the detected subject thermal image. Diagnose the rules and handle them accordingly.
这样，使用者就不必需通过人为的主观判断被摄体热像的形态特征来人工设置分析区域、分析模式、诊断规则，能达到减轻分析区域设置操作的工作量、降低分析区域设置的技术难度、便于设置精准的分析区域、分析模式、诊断规则，快速获得诊断结果、避免拍摄错误部位、角度等的有益效果。In this way, the user does not have to manually set the analysis area, the analysis mode, and the diagnostic rule by subjectively judging the morphological characteristics of the subject thermal image, thereby reducing the workload of the analysis area setting operation and reducing the technical difficulty of the analysis area setting. It is convenient to set accurate analysis area, analysis mode, diagnosis rule, quickly obtain the diagnosis result, avoid the harmful effect of shooting the wrong part and angle.
需要指出，检测部8基于获取部连续获取的热像数据帧进行的检测处理，例如可对连续获取的热像数据帧依次全部进行检测处理，例如也可只读取规定间隔的热像数据帧进行检测处理；例如还对读取的热像数据帧或检测窗口中的热像数据检测前进行了缩小、稀疏等处理；以此，能减轻检测处理负担。It is to be noted that the detection unit 8 performs detection processing based on the thermal image data frames continuously acquired by the acquisition unit. For example, all of the continuously acquired thermal image data frames may be sequentially detected. For example, only the thermal image data frames of a predetermined interval may be read. The detection processing is performed; for example, the processing of the thermal image data in the read thermal image data frame or the detection window is reduced, sparse, and the like before the detection; thereby, the detection processing load can be reduced.
并且，所配置的分析区域、分析模式、诊断规则，并不限定于对检测出特定被摄体热像的热像数据帧进行处理，也用于后续例如规定时间的新获得的热像数据帧的分析诊断等处理。当临时存储部2为存储多帧份的热像数据帧时，甚至可用于分析诊断所检测到具有特定被摄体热像的热像数据帧的时序之前的热像数据帧。可将所配置上述信息，相关联存储在临时存储部的规定区域；便于后续的显示、分析、记录等处理。Further, the configured analysis region, analysis mode, and diagnostic rule are not limited to processing the thermal image data frame in which the specific subject thermal image is detected, and are also used for subsequent newly obtained thermal image data frames such as predetermined time. Analytical diagnosis and other processing. When the temporary storage section 2 stores a plurality of frames of thermal image data frames, it can be used to analyze and diagnose a thermal image data frame before the timing of detecting a thermal image data frame having a specific subject thermal image.

通过规定信息来获得综合的评价值；例如，可以采用所检测的规定信息中的特定信息对应了不同的系数，而由所检测的规定信息中的其他的规定信息结合该系数来获得评价值；例如，如图11中所示，图11(a)检测窗口J1的所对应的0.8，而图11(b)检测窗口J2的窗口系数为0.95，评价值＝相关度的值×窗口系数，因此，当二个窗口中检测到相关度一样的热像数据时，图11(b)所检测出的相关度的值结合检测窗口J2的评价值(例如换算为95％)将大于图11(a)相关度的值结合检测窗口J1的评价值(例如换算为80％)，根据评价值所对应的分析区域，来获得图11(a)的分析区域J1，及图11(b)的分析区域J2和分析区域F1，和各自对应的分析模式、诊断规则。检测到特定被摄体热像的检测窗口，例如代表了该特定被摄体热像大致的位置参数，如期望获得更为精确的特定被摄体热像的位置参数，一个实施方式，可进一步从该检测窗口对应的热像数据中提取特定被摄体热像的轮廓来获得，可获得更为精准的评价值。Obtaining a comprehensive evaluation value by specifying information; for example, the specific information in the detected prescribed information may correspond to different coefficients, and the other specified information in the detected prescribed information is combined with the coefficient to obtain an evaluation value; For example, as shown in FIG. 11, FIG. 11(a) detects the corresponding 0.8 of the window J1, and FIG. 11(b) detects that the window coefficient of the window J2 is 0.95, and the evaluation value = the value of the correlation degree × the window coefficient, When the thermal image data of the same correlation is detected in the two windows, the value of the correlation detected by FIG. 11(b) combined with the evaluation value of the detection window J2 (for example, 95%) will be larger than that of FIG. 11 (a). The value of the correlation is combined with the evaluation value of the detection window J1 (for example, converted to 80%), and the analysis region J1 of FIG. 11(a) and the analysis region of FIG. 11(b) are obtained based on the analysis region corresponding to the evaluation value. J2 and analysis area F1, and their respective analysis modes and diagnostic rules.

步骤B04，如果获得的相关度小于规定的判断值，则检测部8判断没有检测到特定被摄体热像，到步骤B06，当在步骤B04检测到的相关度大于规定的判断值，则进入步骤B05。In step B04, if the obtained correlation degree is smaller than the predetermined determination value, the detecting unit 8 determines that the specific subject thermal image is not detected, and proceeds to step B06, and when the correlation degree detected in step B04 is greater than the predetermined determination value, enters Step B05.
步骤B05，控制部11(具有评价值计算单元，未图示)，根据检测到的规定信息来获得评价值，例如根据下式来获得综合的评价值，评价值＝位置×位置加权系数+尺寸×尺寸加权系数+倾斜角度×倾斜角度加权系数+相关度的值×相关度加权系数；或者，另一种优选的方式，根据所检测到的规定信息与评价值的对照表来获得评价值。In step B05, the control unit 11 (having an evaluation value calculation unit (not shown)) obtains an evaluation value based on the detected predetermined information, for example, obtains a comprehensive evaluation value according to the following formula, and the evaluation value = position × position weighting coefficient + size × size weighting coefficient + tilt angle × tilt angle weighting coefficient + value of correlation degree × correlation weighting coefficient; or, in another preferred mode, an evaluation value is obtained based on the detected comparison table of the prescribed information and the evaluation value.

进一步，可对热像数据帧设置分析区域，根据所配置的分析模式和诊断规则，进行分析和诊断。Further, an analysis area can be set for the thermal image data frame, and analysis and diagnosis can be performed according to the configured analysis mode and diagnostic rule.
如图11所示，图11(a)中所显示的评价值80％，设置分析区域J1；图11(b)中所显示的评价值95％，设置分析区域J2，分析区域F1。 As shown in Fig. 11, the evaluation value 80% shown in Fig. 11(a) is set to the analysis area J1; the evaluation value shown in Fig. 11(b) is 95%, and the analysis area J2 and the analysis area F1 are set.
其中的J1、J2为分析区域设置单元将检测窗口设置为分析区域，根据该分析区域可在分析时能有效的避免降低背景中的其它物体对被摄体热像在分析时的影响，而F1为更加细致的分析区域，用来进一步的细致分析和诊断。Among them, J1 and J2 are analysis area setting units, and the detection window is set as an analysis area, according to which the analysis area can effectively avoid the influence of other objects in the background on the analysis of the subject thermal image, and F1 For more detailed analysis of the area, for further detailed analysis and diagnosis.
进一步，可将分析区域、分析结果、诊断结果与该热像数据帧获得的红外热像进行合成如重叠，而后进行显示。Further, the analysis area, the analysis result, the diagnosis result, and the infrared thermal image obtained by the thermal image data frame may be combined and overlapped, and then displayed.
步骤B06，判断是否退出，如退出，则结束，如未退出，则回到步骤B01，重复上述的处理。In step B06, it is judged whether to exit, if it is exited, it ends. If it is not exited, it returns to step B01, and the above processing is repeated.

Improve the quality of the analysis area and analysis mode, prompt the user, and avoid the cumbersome operation of the user settings.
根据所检测到的规定信息，优选的，能显示不同视觉效果的分析区域，例如在图11(a)的状态，使用者可明白当前并未拍摄获得理想效果的被摄体热像，便于使用者及时采取拍摄调整的措施；当在图11(b)的状态，使用者可明白当前拍摄获得理想效果的被摄体热像；这样，能进一步达到减轻拍摄工作量、避免拍摄错误部位、提示特定检测结果的有益效果。According to the detected predetermined information, preferably, an analysis area capable of displaying different visual effects, for example, in the state of FIG. 11(a), the user can understand that the subject thermal image that does not currently obtain the desired effect is conveniently used. In the state of FIG. 11(b), the user can understand the subject thermal image that is currently photographed to obtain the desired effect; thus, the shooting workload can be further reduced, the wrong part can be avoided, and the prompt can be avoided. The beneficial effects of specific test results.
如上所述，在本实施例中，由于考虑了特定被摄体热像的位置、尺寸、倾斜角度、相关度的值中的一种或任意组合的信息，与分析区域和/或分析模式和/或诊断规则的对应关系，来配置相同或不同的分析区域、分析模式、诊断规则，能及时地提示使用者对特定情况予以注意，能达到大幅度降低拍摄的技术难度、提高被摄体热像的拍摄质量、提高分析区域和分析模式等的设置质量、避免显示过多的分析结果增加使用者工作量、避免不必要的分析结果误导使用者等的有益效果。普通使用者容易掌握这种拍摄技能。当然，实施本发明的实施方式的任一产品并不一定需要同时达到以上所述的所有优点。As described above, in the present embodiment, since the information of one or any combination of the position, the size, the inclination angle, and the correlation value of the specific subject thermal image is considered, the analysis region and/or the analysis mode and / or the corresponding relationship of the diagnostic rules, to configure the same or different analysis areas, analysis modes, diagnostic rules, can prompt users to pay attention to specific situations, can greatly reduce the technical difficulty of shooting, improve the heat of the subject The quality of the image, the improvement of the setting quality of the analysis area and the analysis mode, the avoidance of displaying too many analysis results, the increase in user workload, and the avoidance of unnecessary analysis results to mislead the user. It is easy for ordinary users to master this shooting skill. Of course, implementing any of the products of the embodiments of the present invention does not necessarily require all of the advantages described above to be achieved at the same time.
其他的例子，如图12中所示(省略了分析结果和诊断结果的图示)；检测部8，获得热像数据帧中的规定数量和距离的检测区域中所设置的检测窗口的相关度的值及其对应的位置参数；并且，当从具有规定距离的多个检测窗口中，检测到相关度大于规定的判断值时，意味着检测到多个类似的被摄体热像；根据检测获得的规定信息，可配置各自对应的分析区域、分析模式；可提示使用者、避免过多不必要的分析显示、避免例如衰减而不精确的分析结果误导使用者等的有益效果。Other examples are as shown in FIG. 12 (the illustration of the analysis result and the diagnosis result is omitted); the detecting section 8 obtains the correlation degree of the detection window set in the detection area of the prescribed number and distance in the thermal image data frame. And the corresponding positional parameter; and, when detecting the correlation from the plurality of detection windows having the predetermined distance, the correlation is greater than the specified determination value, meaning that a plurality of similar subject thermal images are detected; The obtained specified information can be configured with corresponding analysis areas and analysis modes; the user can be prompted to avoid excessive unnecessary analysis display, and avoid the beneficial effects such as attenuation and inaccurate analysis results misleading the user.
实施例3Example 3
实施例3与实施例1，2的不同之处在于，所述检测部8，用于基于获取的热像数据帧，检测所述热像数据帧中的特定被摄体热像的规定信息；所述分析部6，根据规定的辅助信息及检测部8检测获得的规定信息，来配置与分析有关的分析区域和/或分析模式和/或诊断规则，并按照所配置的分析区域和/或分析模式和/或诊断规则进行分析和诊断。 Embodiment 3 is different from Embodiments 1 and 2 in that the detecting unit 8 is configured to detect predetermined information of a specific subject thermal image in the thermal image data frame based on the acquired thermal image data frame; The analysis unit 6 arranges the analysis region and/or the analysis mode and/or the diagnosis rule related to the analysis based on the predetermined auxiliary information and the predetermined information that the detection unit 8 detects, and according to the configured analysis region and/or Analyze patterns and/or diagnostic rules for analysis and diagnosis.
具体而言，根据规定的辅助信息及规定信息来获得评价值，根据评价值与分析配置信息的对照表，来配置分析区域和/或分析模式和/或诊断规则，进行分析诊断。所述分析配置信息，至少包括了分析区域、分析区域、诊断规则中的一项或多项有关的配置信息；Specifically, the evaluation value is obtained based on the predetermined auxiliary information and the predetermined information, and the analysis region and/or the analysis mode and/or the diagnostic rule are arranged based on the comparison table of the evaluation value and the analysis configuration information, and the analysis diagnosis is performed. The analyzing configuration information includes at least one or more related configuration information in an analysis area, an analysis area, and a diagnosis rule;
所述规定信息，至少包括特定被摄体热像的位置、尺寸、倾斜角度、相关度的值中的一种或任意组合的信息。所述辅助信息，可包括规定信息之外的其他各种对分析、诊断有影响的因素，都在其范围中。所述辅助信息，例如至少包括分析值、诊断结果、环境温度、背景因素、风速、湿度、距离中的一种或任意组合的信息。 The predetermined information includes at least one of a position, a size, an inclination angle, and a value of a correlation of a specific subject thermal image, or any combination thereof. The auxiliary information may include various factors other than the prescribed information that affect the analysis and diagnosis, and are all within the scope thereof. The auxiliary information includes, for example, at least one of an analysis value, a diagnosis result, an ambient temperature, a background factor, a wind speed, a humidity, a distance, or any combination.
辅助信息，例如可以根据热像装置100中包含的功能部件，或与热像装置100连接的相应功能的部件(未图示)来获取上述辅助信息；例如，通过分析部件获取的分析值，所述分析值并不限定于温度值，例如也可以是热像AD值、伪彩热像中的颜色值、特定像数值的比例，或还将这些数值按照规定公式计算获得的值等，分析部件所获取的分析值可以针对热像数据帧中的全部像素或特定分析区域中的像素；例如，通过温度传感器来获取环境温度；例如通过湿度计来获得湿度；例如通过测距仪来获得热像装置100与被摄体的距离等。The auxiliary information may be obtained, for example, according to a functional component included in the thermal imaging device 100 or a corresponding functional component (not shown) connected to the thermal imaging device 100; for example, an analysis value obtained by analyzing the component, The analysis value is not limited to the temperature value, and may be, for example, a thermal image AD value, a color value in a pseudo color thermal image, a ratio of a specific image value, or a value obtained by calculating these values according to a prescribed formula, etc., and analyzing the component. The acquired analysis values may be for all pixels in the thermal image data frame or pixels in a particular analysis region; for example, by ambient temperature to obtain ambient temperature; for example, by a hygrometer to obtain humidity; for example, by a rangefinder to obtain a thermal image The distance between the device 100 and the subject, and the like.
辅助信息，例如也可以根据存储介质中预先存储的上述辅助信息来获取，例如，辅助信息的历史数据；或结合当前测量获取的辅助信息，与存储介质中预先存储的辅助信息的历史数据的对比来获得的辅助信息。例如也可由使用者进行设置的辅助信息。The auxiliary information may be acquired, for example, according to the auxiliary information stored in advance in the storage medium, for example, historical data of the auxiliary information; or the auxiliary data acquired in combination with the current measurement, and the historical data of the auxiliary information stored in advance in the storage medium. To get the auxiliary information. For example, the auxiliary information set by the user can also be performed.
在红外检测的应用领域，根据上述的辅助信息的不同，所获得的热像数据帧的质量及重要程度不同，应有不同的条件来应对规定的热像数据帧的设置分析区域的处理；例如，当获得的特定被摄体热像中具有大于规定的对比值(例如缺陷的阀值)的分析值时，代表被摄体具有缺陷，那么，这时即便在相关度接近的情况下，也优先对分析值超标的热像数据帧进行更为细致的分析，设置较为细致的分析区域，对红外检测的意义重大；而对未大于规定的对比值的被摄体热像，可设置简单的分析区域或显示少量的分析结果数据，以免分析结果数据过多而增加了使用者观察工作量。例如考虑环境温度、背景、风速、背景因素(例如背景与被摄体热像的差异性，背景的热场分布等)等的影响因素，在相关度接近的情况下，这些影响因素可能会导致不同的热像质量及后续分析的价值降低，应选择不同的分析区域和/或分析模式和/或诊断规则来降低其他影响因素干扰的影响。In the field of application of infrared detection, according to the above-mentioned auxiliary information, the quality and importance of the obtained thermal image data frame are different, and different conditions should be met to deal with the setting analysis area of the specified thermal image data frame; for example; When the obtained specific thermal image of the subject has an analysis value larger than a prescribed contrast value (for example, a threshold value of a defect), the representative object has a defect, and then, even when the correlation is close, It is preferred to perform more detailed analysis on the thermal image data frames whose analytical values exceed the standard, and to set a more detailed analysis area, which is of great significance for infrared detection; and for the thermal image of the subject not larger than the specified contrast value, it can be set simple. Analyze the area or display a small amount of analysis result data, so as to avoid too much analysis result data and increase the user observation workload. For example, considering factors such as ambient temperature, background, wind speed, background factors (such as the difference between the background and the thermal image of the object, the thermal field distribution of the background, etc.), these factors may be caused when the correlation is close. Different thermal image quality and subsequent analysis values are reduced. Different analysis areas and/or analysis modes and/or diagnostic rules should be selected to reduce the influence of other influencing factors.
通过规定信息和辅助信息来获得综合的评价值；例如，可以采用规定信息或辅助信息中的特定信息对应了不同的系数，而由其他的规定信息或辅助信息结合该系数来获得评价值。或也可以采用不同的特定信息所占的权重，通过加权来获得评价值；例如，获得综合了特定被摄体热像的位置、尺寸、倾斜角度、辅助信息、相关度的值，获得的评价值，例如根据下式来获得综合评价值，综合评价值＝位置×位置加权系数+尺寸×尺寸加权系数+倾斜角度×倾斜角度加权系数+辅助信息×辅助信息的加权系数+相关度的值×相关度加权系数。或根据所述规定信息和所述辅助信息与综合评价值的对照表来获得评价值。The comprehensive evaluation value is obtained by specifying the information and the auxiliary information; for example, the specific information in the predetermined information or the auxiliary information may be used to correspond to different coefficients, and the other predetermined information or auxiliary information may be combined with the coefficient to obtain the evaluation value. Alternatively, the weight of the specific information may be used to obtain the evaluation value by weighting; for example, obtaining the value of the position, size, inclination angle, auxiliary information, and correlation of the specific subject thermal image, and obtaining the evaluation Value, for example, a comprehensive evaluation value is obtained according to the following formula, comprehensive evaluation value = position × position weighting coefficient + size × size weighting coefficient + inclination angle × inclination angle weighting coefficient + auxiliary information × weighting coefficient of auxiliary information + value of correlation × Correlation weighting factor. Or, the evaluation value is obtained based on the prescribed information and a comparison table of the auxiliary information and the comprehensive evaluation value.
而后，根据评价值与分析区域和/或分析模式和/或诊断规则的对应关系，例如评价值与分析配置信息的对照表，来配置分析区域和/或分析模式和/或诊断规则。The analysis area and/or the analysis mode and/or the diagnostic rule are then configured based on a correspondence between the evaluation value and the analysis area and/or the analysis mode and/or the diagnostic rule, such as a comparison table of the evaluation value and the analysis configuration information.

步骤C04，如果规定数量的检测窗口获得的相关度都小于规定的判断值，则检测部8判断没有检测到特定被摄体热像，回到步骤C01，重复后续的处理，当在步骤C04检测到的相关度大于规定的判断值，则进入步骤C05。In step C04, if the correlation obtained by the predetermined number of detection windows is smaller than the predetermined determination value, the detecting unit 8 determines that the specific subject thermal image is not detected, returns to step C01, repeats the subsequent processing, and detects in step C04. If the degree of correlation is greater than the predetermined judgment value, the process proceeds to step C05.

The region, and then the analysis region F1 set according to the comparison table of the analysis value and the analysis region and the corresponding analysis mode and diagnosis rule; the analysis result and the diagnosis result of the analysis region F1 can be further analyzed in detail.
步骤C06，判断是否退出，如退出，则结束，如未退出，则回到步骤C01，重复上述的处理。In step C06, it is judged whether to exit, if it is exited, it ends. If it is not exited, it returns to step C01, and the above processing is repeated.
