Embodiment Construction

[0031] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0032] see figure 1 , a page content recognition system, comprising a camera unit 100, a processing unit 102, the camera unit 100 is used to acquire image information of a plurality of interleaved pages, the image information includes all or part of the top page, and The non-coverage area where the lower page is not covered by the upper page. The processing unit 102 is configured to identify, according to the image information, the content of the non-occluded pages stacked in a staggered manner and the residual content of the non-coverage area of ​​the occluded page. In our embodiment, the staggered pages include that the upper page covers the left area of ​​the lower page; or the upper page covers the right area of ​​the lower page;...

Abstract

An exercise book content identification method is characterized in that an exercise book is formed by binding a plurality of answer sheets along the edge of the same side, and an answer area is printed on the other side of each answer sheet. The exercise book content identification method comprises the following steps; acquiring image information of a plurality of answer sheets which are stacked in a staggered manner, wherein the image information comprises all or part of the answer sheet at the uppermost part and a non-coverage area where the answer sheet at the lower part is not covered by the answer sheet at the upper part; and identifying the content of the unshielded answer sheet and the residual content of the non-covered area of the shielded answer sheet which are stacked in a staggered manner according to the image information. According to the scheme, after a user stacks the edges of one side of the exercise book in a staggered manner, the uppermost part and the residual partof the page can be identified. And the contents of the coverage area and the non-coverage area as different pages are identified. Meanwhile, the answer area is arranged on one side of the non-bindingedge, and the technical effect of better answer area content extraction can be achieved by distinguishing the content of the unshielded page and the residual content, thus facilitating subsequent identification operations.

Description

technical field [0001] The invention relates to the field of online teaching, in particular to an image-based technology for identifying and optimizing answer content. Background technique [0002] The existing answer sheet is the carrier of information input by the cursor reader, and is a general term for various information input forms of the supporting cursor reader. The information card converts the information needed by the user into selectable options for the user to scribble. The OMR equipment restores the information according to the coating and unpainting of the information points and the format file settings. [0003] The style of the information card is designed according to the information input into the computer and according to the format required by the design specification of the cursor reader. [0004] However, in practical applications, the recognition of the special answer sheet causes the user to switch back and forth between the test paper and the answ...
