Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, in an embodiment, a method for optimizing a test question picture is provided, where the method for optimizing a test question picture can be applied to a terminal or a server, and the embodiment is exemplified by being applied to the server. The test question picture optimization method specifically comprises the following steps:
The initial test question picture refers to a qualified test question picture which is pre-input to the server, and an initial test question picture library is formed for a plurality of initial test question pictures so as to be used as a standard for judging whether the test question pictures shot or uploaded by a user meet the optimized balance. The first test question information refers to content information of the initial test question picture, such as OCR content information, and the first picture parameter refers to a parameter reflecting the quality of the initial test question picture, for example, color information, resolution, integrity or angle of the test question picture, and the like.
And 104, when receiving a picture warehousing instruction, acquiring a picture of the to-be-warehoused test questions contained in the picture warehousing instruction, and identifying the picture of the to-be-warehoused test questions to obtain second test question information and second picture parameters of the picture of the to-be-warehoused test questions.
The picture to be put in storage is a test question picture shot or uploaded by a user, the second test question information is content information of the test question picture to be put in storage, and the second picture parameter is a quality parameter of the test question picture to be put in storage. And the determining methods of the first test question information and the second test question information are consistent, for example, an OCR (optical character recognition) method is used for recognition and acquisition, and the parameter types of the first picture parameter and the second picture parameter are consistent with the determining method. It can be understood that, in this embodiment, by obtaining the picture of the test questions to be put in storage, based on the comparison between the picture of the test questions to be put in storage and the initial picture of the test questions, it is further ensured that the subsequent picture of the test questions with better quality and richer question amount can be selected.
And 106, searching in the initial test question picture library based on the second test question information.
Specifically, the second test question information is used as a retrieval condition, retrieval is carried out in the initial test question picture library, whether the content information of the test question picture to be put in the library is repeated with the content of one initial test question picture in the initial test question picture library or not is determined according to the retrieval result, and therefore the accuracy of subsequent optimization of the initial test question picture library is guaranteed.
And step 108, if the first test question information consistent with the second test question information exists, taking the initial test question picture corresponding to the first test question information consistent with the second test question information as a candidate picture.
The candidate pictures refer to initial test question pictures which are repeated with the contents of the test question pictures to be put in storage. Specifically, when the first test question information consistent with the second test question information exists, it is indicated that the content of the to-be-put test question picture is repeated with the content of one initial test question picture in the initial test question picture library, so that the initial test question picture corresponding to the first test question information consistent with the second test question information is taken as a candidate picture, and then quality comparison is performed subsequently based on the candidate picture, so as to realize automatic iteration and optimization of the test question picture.
And 110, comparing the first picture parameter and the second picture parameter of the candidate picture according to a preset comparison rule, deleting the candidate picture when the second picture parameter is superior to the first picture parameter, and warehousing the picture to be warehoused to the initial test question picture library.
The preset comparison rule is used for comparing the quality of the test question picture to be stored and the initial test question picture. For example, the size of one parameter included in the first picture parameter and the second picture parameter may be directly compared, or the result of calculating each parameter included in the first picture parameter and the second picture parameter according to the calculation rule of weighted summation may be compared. As the optimization in the embodiment, the latter comparison rule is selected to ensure the accuracy and comprehensiveness of the comparison.
When the second picture parameter is superior to the first picture parameter, the quality of the picture of the test question to be put in storage is indicated to be better, so that the candidate picture is deleted, the picture of the test question to be put in storage is put into the initial test question picture library, automatic iteration and optimization of the initial test question picture library are realized, and the quality of the initial test question picture library is improved.
And step 112, if the first test question information consistent with the second test question information does not exist, constructing a second test question picture library, and warehousing the test question pictures to be warehoused into the second test question picture library.
Specifically, when the first test question information consistent with the second test question information does not exist, the test questions in the to-be-put test question picture are shown as new questions, so that the second test question picture library is constructed, and the to-be-put test question picture is put into the second test question picture library, so that the problem quantity expansion of the test question picture is realized, and the richness of the problem quantity of the test question picture is improved.
The method for optimizing the test question picture comprises the steps of constructing an initial test question picture library, wherein the initial test question picture library comprises a plurality of initial test question pictures, first test question information and first picture parameters of each initial test question picture; when a picture warehousing instruction is received, acquiring a picture of the test questions to be warehoused, which is contained in the picture warehousing instruction, identifying the picture of the test questions to be warehoused, and obtaining second test question information and second picture parameters of the picture of the test questions to be warehoused; searching in the initial test question picture library based on the second test question information; if the first test question information consistent with the second test question information exists, taking an initial test question picture corresponding to the first test question information consistent with the second test question information as a candidate picture; comparing the first picture parameter and the second picture parameter of the candidate picture according to a preset comparison rule, deleting the candidate picture when the second picture parameter is superior to the first picture parameter, and warehousing the picture of the test question to be warehoused into the initial test question picture library; and if the first test question information consistent with the second test question information does not exist, constructing a second test question picture library, warehousing the test question pictures to be warehoused into the second test question picture library, and automatically iterating and warehousing the test question pictures by combining the comparison of the initial test question picture library, so that the picture question quality is automatically optimized, the question quantity of the test question pictures is expanded, and the experience of a user in answering the test questions is improved.
It should be noted that, for the second test question picture library, when a test question picture to be put into a library is subsequently received, the method from step 102 to step 112 may be adopted to continuously optimize the second test question picture library, and construct a third test question picture library, so as to further optimize and iterate the test question picture, and further expand the question amount of the picture questions.
As shown in fig. 2, in an embodiment, the picture of the test questions to be put in storage is obtained by controlling the shooting device to shoot the picture questions according to a preset shooting mode, where the preset shooting mode includes:
and step 104B, when the question number information of the picture question is detected, setting at least one sub-shooting frame in the shooting frame according to the question number information and the corresponding question number position, and adjusting the interval of each sub-shooting frame to be consistent with the interval between the question numbers for shooting to obtain the picture of the question to be put in storage.
In this embodiment, a shooting frame is set when a shooting interface of the shooting device is started, for example, an interface of a picture to be shot by a user, a shooting mine with two horizontal and vertical guide lines is set, and the user is guided to adjust the horizontal and vertical directions of the picture of the test question, so as to obtain a more standard picture of the test question to be put in storage. Further, when the question number information of the picture questions is detected, the user can automatically pre-frame the test questions according to the question number information and the question number positions when photographing the picture questions, namely, each question number is provided with one sub-photographing ore, and the interval of each sub-photographing frame is adjusted to be consistent with the interval between the question numbers for photographing, so that the standard picture of the test questions to be put in storage is obtained. In this embodiment, the accuracy of the angle of the to-be-put-in test question picture is ensured by setting the shooting frame, so that the to-be-put-in test question picture is more standard.
As shown in fig. 3, in an embodiment, the second test question information and/or the first test question information includes key text information of the test question, and the second picture parameter and/or the first picture parameter includes a picture file memory, a resolution, a color value, and a completeness; identifying the picture of the test questions to be put in storage to obtain second test question information and second picture parameters of the picture of the test questions to be put in storage, wherein the steps comprise:
In this embodiment, an optical character recognition algorithm is first used to recognize the initial test question picture and the to-be-put test question picture to obtain first test question information and second test question information. Acquiring pixel information of a to-be-put test question picture through a pixel acquisition tool in the OPENCV; according to a calculation formula of a picture file memory: the picture file memory is calculated as the memory space occupied by the picture length (pixel) × the picture width (pixel) × one pixel. According to a calculation formula of the resolution: the resolution is calculated as a picture length (pixel) × picture width (pixel). The bit depth refers to the number of bits used to store each pixel, and the color depth refers to how many bits are used to store the color for each pixel. The color depth and the bit depth of the picture of the test question to be put in storage are obtained, and the color value is determined according to the color depth and the bit depth, for example, the sum or the product of the color depth and the bit depth can be calculated to be used as the color value. The integrity is a parameter for reflecting the integrity of the picture of the test questions to be put in storage, and the integrity can be determined according to the key character information of the test questions in the first test question information and the key character information of the test questions in the second test question information, for example, when the key character information of the test questions in the first test question information and the key character information of the test questions in the second test question information are completely consistent, the integrity in the second picture parameter is determined to be 100%, the first test question information in the initial test question library includes the second test question information, the integrity in the second picture parameter is determined to be less than 100%, and specifically, the integrity can be set to be 0. Or, the integrity is determined according to the second test question information, and the integrity in the second picture parameter can be judged according to the semantic information of the second test question information. In this embodiment, quantitative calculation of the second picture parameter is realized by analyzing the picture of the test question to be put in storage, so that more accurate comparison and optimization can be performed subsequently based on the second picture parameter. It should be noted that the calculation method of the first picture parameter of the initial test question picture is consistent with the calculation method of the second picture parameter, so as to ensure the accuracy of the subsequent comparison.

Whether picture information or table information consistent with the semantics of the key word information of the test question exists or not is detected in the second test question information, when the picture information or the table information consistent with the semantics of the key word information of the test question exists, the second detection result is judged to be complete, and when the picture information or the table information consistent with the semantics of the key word information of the test question does not exist, the second detection result is judged to be incomplete, for example, the key words of the test question include 'like a picture', 'see a table' and the like, but the picture information or the table information does not exist in the second test question information, so that the high-efficiency detection of the integrity in the second picture parameter is realized.
