Problems solved by technology

[0002] In the exam marking process, the teacher manually marks the paper test papers and fills in the scores obtained for each question. After the marks are completed, the teacher manually calculates the total score of each candidate, and summarizes the scores of all candidates. Statistics include score statistics, scores of each test question, degree of difficulty, degree of differentiation of test papers, reliability of test papers, etc. The process of manually counting the scores of test papers requires teachers to spend more time and energy, and increases the workload of teachers
[0003] In the prior art, answer sheets are also used, and the scores of the questions in the answer sheet are calculated by machine recognition of the answer sheet, and statistical summary is performed. Then, the scope of application of the answer sheet is limited, limited to the multiple-choice questions in the test paper, and cannot be counted. The scores of other types of test questions, and the cost of the answer sheet has also increased a lot compared with the existing traditional test papers

Embodiment 1

[0070] Please refer to figure 1 Shown, a kind of test paper score automatic statistics method, it comprises the following steps:

[0071] Step 1. Perform image acquisition on the target test paper to obtain the initial image.

[0072] The target test paper is the test paper for which scores are to be counted. It can be one test paper or multiple test papers of the same type (that is, one class and one grade of the same type, such as Chinese test papers). Here, one test paper is used as the score of the target test paper Statistics are used as an example to explain and illustrate.

[0073] The image of the target test paper collected by the image acquisition device is used to obtain an initial image to figure 2 The initial image shown is taken as an example, and the initial image is stored in a storage device for the call of the fitting process in step 2. The process of image acquisition and storage and the process of recognition adopt dual threads.

[0074] Step 2. Fitting...

Embodiment 2

[0109] Embodiment 2 discloses a kind of test paper score automatic counting device corresponding to the above-mentioned embodiment, which is the virtual device structure of the above-mentioned embodiment, please refer to Figure 9 shown, including:

[0110] An image acquisition module 71, configured to perform image acquisition on the target test paper to obtain an initial image;

[0111] Fitting module 72, is used for fitting described initial image, to obtain the target digital area image in initial image, described target digital area image is the fitting image that comprises a plurality of handwritten numerals;

[0112] Segmentation module 73, is used for dividing described fitted image by integral centroid method, obtains segmented image, and the number of described segmented image is the quantity of preset category;

[0113] Training module 74, is used for applying MNIST data set as training sample, single handwritten digit recognition algorithm model LeNet-5 is trained...

Embodiment 3

[0117] Figure 10 A schematic structural diagram of an electronic device provided in Embodiment 3 of the present invention, such as Figure 10 As shown, the electronic device includes a processor 81, a memory 82, an input device 83 and an output device 84; the number of processors 81 in the computer device can be one or more, Figure 10 Take a processor 81 as an example; the processor 81, memory 82, input device 83 and output device 84 in the electronic equipment can be connected by bus or other methods, Figure 10 Take connection via bus as an example.

[0118] Memory 82, as a computer-readable storage medium, can be used to store software programs, computer-executable programs and modules, such as program instructions / modules corresponding to the method for automatically counting test paper scores in the embodiment of the present invention (for example, an automatic test paper score counting device The image acquisition module 71, the fitting module 72, the segmentation mo...

Abstract

The invention discloses an automatic statistic method for test paper scores, comprising the following steps: image acquisition of a target test paper to obtain an initial image; fitting of the initial image to obtain an image of a target digital area in the initial image; The fitting image is segmented by the method to obtain segmented images; the two-digit handwritten digit recognition algorithm model LeNetT is obtained; each segmented image is recognized according to the single handwritten digit recognition algorithm model LeNet‑5 and the two-digit handwritten digit recognition algorithm model LeNetT , obtain the target score; perform statistical analysis on the target score. The invention also discloses an automatic statistic of test paper scores, an electronic device and a computer-readable storage medium. The invention automatically recognizes the scores of each question by collecting images of the test paper, so as to realize the statistical analysis of the test paper scores.
