Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
For the convenience of understanding the mobile terminal provided in the embodiment of the present invention, an application scenario thereof will be described first. The mobile terminal can be a mobile phone, a notebook computer and other devices which are convenient to move, and is used for assisting a user of the mobile terminal to determine the specific position of the target object, so that the user is assisted to find the target object. The following describes a mobile terminal according to an embodiment of the present invention in detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the mobile terminal 10 according to the embodiment of the present invention includes a camera 20 for scanning a comparison object to obtain an image of the comparison object, and a display device 30 for displaying the image of the comparison object. The mobile terminal 10 further includes an input module 40 for inputting feature information of a target object, and an analysis and processing module 50 for constructing a target image according to the input feature information. The analysis and processing module 50 is further configured to compare and analyze the similarity between the image of the comparison object and the target image, and prompt when the comparison image with the similarity exceeding the set value is compared and analyzed.
In the above solution, the user of the mobile terminal 10 inputs the characteristic information of the target object to be searched in the input module 40, and uses the camera 20 to scan the surrounding objects to pick up the comparison object, so that the processing and analyzing module automatically performs comparison analysis on the target image and the comparison object, and when the comparison image with the similarity exceeding the set value is compared and analyzed, the mobile terminal 10 can prompt to assist the user of the mobile terminal 10 to quickly determine the position of the target object to be searched. The above components are described in detail below.
First, the camera 20 is described, and the camera 20 is a conventional camera device having a scanning function to pick up an image in the prior art, and may be specifically a camera 20 on a mobile phone, a camera 20 on a notebook computer, a camera 20 on a tablet computer, and the like. When the mobile terminal 10 is used, a user of the mobile terminal 10 holds the mobile terminal 10 and moves the mobile terminal, so that the camera 20 can pick up surrounding objects, and an image of the comparison object is formed.
When the display device 30 is disposed, the display device 30 is a conventional display screen capable of displaying images in the prior art, and may specifically be a display screen on a mobile phone, a display screen on a notebook, a display screen on a tablet computer, and the like according to the type of the mobile terminal 10. When the comparison system is applied, after the camera 20 picks up the surrounding objects and forms the image of the comparison object, the camera 20 transmits the image of the comparison object to the display device 30, and the display device 30 displays the image of the comparison object, so that a user can find a target object on the display device 30 conveniently. The reason is that, with the development of the image capturing technology, the number of frames of the picked-up image is higher and higher, so that the image displayed by the display device 30 is clearer and clearer, and the visibility of the image observed by the user in the display device 30 is higher than the visibility of the image observed directly from the surrounding objects, so that the user can search for the target object through the image displayed in the display device 30.
When the input module 40 is provided, it is specifically a module that can interact information with a user on the mobile terminal 10 in the prior art, for example, it may be specifically the input module 40 on a mobile phone, the input module 40 on a tablet computer, and the like. In a specific setting, the input module 40 may be configured to have a plurality of category options for characterizing categories of the target object, and each category option has a plurality of feature information options for identifying a corresponding category. For example, the input module 40 may be set with a type of a specific object, which may be a key, a remote controller, a person, a pen, or the like. Specific characteristic information of different targets can be set, for example, when the type of the target is set as a key, the characteristic information can be information such as color, size, identification pattern and the like; when the type of the target object is set as a remote controller, the characteristic information can be color, shape and the like; when the category to which the target is set is a person, the characteristic information may be sex, height, or the like. By setting the type and specific feature information of the target object in the input module 40 in advance, the analysis and processing module 50 can construct the target image conveniently, thereby realizing modularization.
When the analysis and processing module 50 is installed, the analysis and processing module 50 is a functional module having functions of image comparison, analysis, processing, and the like in the prior art. When the analysis and processing module 50 constructs the target image according to the feature information input by the user, it may form the general shape and the target image of different target objects in advance through modeling, image scanning and recording, etc., and then store the pre-constructed target image, and after the user inputs the corresponding feature information, the analysis and processing module 50 may call up the corresponding target image. It should be understood that the above only shows one way of constructing the target image, and that other ways may be used in addition to this. Then, the camera 20 or the display device 30 transmits the captured or displayed comparison image to the analysis and processing module 50 for comparison and analysis, wherein the comparison and analysis is performed in a manner of comparing the similarity between two images in the prior art. The similarity is an index representing the similarity between two images in the prior art, and when the similarity of the two images is high, the two images are relatively close, and when the similarity of the two images is low, the difference between the two images is relatively large. When the analysis and processing module 50 compares the target image with the comparison object image, a set value of the similarity may be preset, and when the comparison and analysis module compares and analyzes the comparison object image with the similarity exceeding the set value, it indicates that a comparison image closer to the target image exists, and the target object to be searched may be in the comparison object scanned by the camera 20, so the analysis and processing module 50 may prompt the user of the mobile terminal 10 to pay attention.
When the prompt mode is specifically set, a marking mode may be adopted, specifically, color processing may be performed on the comparison object image displayed on the display device 30 by marking yellow, marking red, showing blue, and the like, and a marking mark, a circling mark, and the like may be performed on the comparison object image displayed on the display device 30, so as to prompt that the comparison object, which may be the target object, of the user of the mobile terminal 10 may be in the comparison object that has just been scanned, and the specific position is already marked in the display device 30, and the user may determine the specific position where the comparison object is located by the position of the comparison object image with the mark in the display device 30, thereby facilitating finding the comparison object. It should be understood that the manner of prompting is not limited to that shown above, and other manners may be adopted in addition to this. For example, a warning sound prompting mode may also be adopted, specifically, when the analysis and processing module 50 compares and analyzes the comparison image with the similarity exceeding the set value, the mobile terminal 10 sends a warning sound to prompt, at this time, the user of the mobile terminal 10 may stand still, the general position of the target object is determined according to the direction in which the camera 20 faces and the position that the camera has just moved, and then further searching is performed to verify whether the comparison object with the higher similarity is the target object. It should be noted that the above-mentioned means of marking and warning sound may be used alone or in combination. The user of the mobile terminal 10 is assisted in quickly finding the target object by marking the image with higher similarity in the display device 30 and/or giving out warning sound prompt to remind the user of the mobile terminal 10 of comparing the general position of the object.
Referring to fig. 3, the analyzing and processing module 50 is further configured to control the display device 30 to enlarge the comparison image with the similarity exceeding the set value, so as to further verify whether the comparison object image with higher similarity is the target object to be searched. The user of the mobile terminal 10 may "zoom in" and zoom in on the marked image on the display device 30 to further verify whether the target object is to be found based on the image, if applicable. After amplification, the marked comparison object is determined to be a target object, which indicates that the specific position of the target object is determined, and scanning can be finished; if the marked comparison object is determined not to be the target object after amplification, the search can be continued. By enlarging the comparison image with the similarity exceeding the set value, the user of the mobile terminal 10 can further determine whether the target object to be found is consistent with the comparison object with the higher similarity. In addition, a navigation module with a navigation function may be further disposed on the analysis and processing module 50, and after the target object is determined to be scanned, the comparison object image with a higher similarity may be clicked on the display device 30, and the navigation module is selectively turned on to assist the user of the mobile terminal 10 to find the target object.
Since it takes time for the camera 20 to transmit the comparison object image information to the display device 30 and for the display device 30 to display the comparison object image, a delay occurs, which causes the comparison object image displayed by the display device 30 to be inconsistent with the image oriented by the camera 20 on the mobile terminal 10, and there may be a case that the comparison image with the similarity exceeding the set value is not displayed on the display device 30. At this time, the analysis and processing module 50 may further analyze the position direction of the comparison object corresponding to the comparison image with the similarity exceeding the set value, and specifically, the analysis and processing module 50 may determine the specific position of the comparison object corresponding to the comparison image with the similarity exceeding the set value by the scanning direction of the camera 20 and the relative position between the comparison image with the similarity exceeding the set value and other images. For example, when the user of the mobile terminal 10 scans in a first direction and the mobile terminal 10 has sent an alert tone, but no marked image is displayed on the display device 30, indicating that the camera 20 may have scanned past, at which time the user should scan in a second direction opposite to the first direction, a direction indication that the user should scan in a certain direction may be displayed on the display device 30 so as to alert the user of the mobile terminal 10 of the particular operating mode. Specifically, when the display screen is rectangular, the user of the mobile terminal 10 may be reminded by displaying arrow marks at four edges of the display screen. The position direction of the comparison object is displayed on the display device 30 to remind the user of the mobile terminal 10 to adjust the scanning direction of the camera 20, so that the target object can be found quickly.
The user of the mobile terminal 10 inputs the characteristic information of the target object to be searched in the input module 40, and uses the camera 20 to scan the surrounding objects to pick up the comparison object, so that the processing and analyzing module automatically performs comparison analysis on the target image and the comparison object, and when the comparison image with the similarity exceeding the set value is compared and analyzed, the mobile terminal 10 can prompt to assist the user of the mobile terminal 10 to quickly determine the position of the target object to be searched.
In addition, the embodiment of the present invention further provides a method for searching for a target object, referring to fig. 1 and fig. 2, the method includes inputting feature information of the target object in the input module 40; the camera 20 scans the comparison object to obtain an image of the comparison object; the display device 30 displays the image of the comparison object; the analysis and processing module 50 constructs a target image according to the inputted feature information, and compares and analyzes the image of the comparison object and the similarity of the target image. When the analysis and processing module 50 compares and analyzes the comparison image with the similarity exceeding the set value, a prompt is given. The user of the mobile terminal 10 inputs the characteristic information of the target object to be searched in the input module 40, and uses the camera 20 to scan the surrounding objects to pick up the comparison object, so that the processing and analyzing module automatically performs comparison analysis on the target image and the comparison object, and when the comparison image with the similarity exceeding the set value is compared and analyzed, the mobile terminal 10 can prompt to assist the user of the mobile terminal 10 to quickly determine the position of the target object to be searched.
The input module 40 has a plurality of category options for characterizing categories of the target object, and each category option has a plurality of feature information options for identifying a corresponding category, where the feature information of the target object input in the input module 40 may specifically be: and selecting the category option of the target object from the plurality of category options, and selecting the characteristic information of the target object from the corresponding category options. By setting the type and specific feature information of the target object in the input module 40 in advance, the analysis and processing module 50 can construct the target image conveniently, thereby realizing modularization.
When the analysis and processing module 50 compares and analyzes the comparison image with the similarity exceeding the set value, the prompt may specifically be: when the analysis and processing module 50 compares and analyzes the comparison image with the similarity exceeding the set value, the comparison image with the similarity exceeding the set value is marked and/or a warning sound is given. The user of the mobile terminal 10 is assisted in finding the target object quickly by marking the image with higher similarity in the display device 30 or giving out a warning sound prompt to remind the user of the mobile terminal 10 of comparing the general position of the object.
Referring to fig. 3, the searching method further includes the analyzing and processing module 50 controlling the display device 30 to enlarge the comparison image with the similarity exceeding the predetermined value. By enlarging the comparison image with the similarity exceeding the set value, the user of the mobile terminal 10 can further determine whether the target object to be found is consistent with the comparison object with the higher similarity.
In addition, the analysis and processing module 50 is further configured to analyze the position direction of the comparison object corresponding to the comparison image with the similarity exceeding the set value and control the display device 30 to display the position direction when the comparison image with the similarity exceeding the set value is compared and analyzed and the comparison image is not displayed on the display device 30. The position direction of the comparison object is displayed on the display device 30 to remind the user of the mobile terminal 10 to adjust the scanning direction of the camera 20, so that the target object can be found quickly.
