[0043] An intelligent test paper correction method, such as figure 1 As shown, the method includes the following steps S1 to S6:
[0044] S1, obtain the original test paper image to be recognized, and find the target test paper image corresponding to the original test paper to be recognized through the question bank;
[0045] Wherein, the original test paper image is collected by a camera, and the target test paper image is a test paper template PDF page, see figure 2 and image 3 .
[0046] S2, use the alignment algorithm to correct and align the original test paper image with the target test paper image; see Figure 4 .
[0047] The alignment algorithm is an existing image recognition algorithm, which will not be repeated here.
[0048] S3, aligning the questions in the image of the target test paper, and correspondingly obtaining the topic-cutting information of the original test paper image according to the information about the questions in the image of the target t...

[0063] The specific process of determining the standard answer area corresponding to all answer information in each question according to the standard answer area and all answer information of each question in the target test paper image in step S5 is described by taking part of the question-cutting information of the test paper as an example.
[0064] like Figure 7 As shown, the larger box in the figure is the standard answering position, and the smaller box is the user answering position. Then, "X" in the matching diagram is the user's answer.
[0065] like Figure 8 As shown, there is only one standard answer for this question, although the user's answer is not in the standard area, according to the number, "X" is still used as the user's answer.
[0066] like Figure 9 As shown, the larger boxes 1, 2, and 3 are the standard answer positions for this question. If two lines of answers, A and B, are detected in the photo submitted by the user, then A corresponds to the a...

[0082] In hardware the invention is typically implemented based on computer equipment, which typically includes a processor, a memory, a network interface and a database. The processor is used to provide computing and control capabilities, and the memory includes a non-volatile storage medium and an internal memory. The non-volatile storage medium may store an operating system, a computer program and a database; the internal memory may provide an environment for the operation of the operating system and the computer program in the non-volatile storage medium, and the embodiments are implemented by running the computer program 1 Smart test paper correction scheme.
