Abstract

The invention provides a hand-written answer sheet automatic processing and marking method based on mobile phone photographing, comprising: preserving standard answers corresponding to test paper at a server side; preserving the blank answer sheet area segmentation information corresponding to the test paper at the server side; photographing answer sheets, sending images of the answer sheets to the server side, and automatically performing step-by-step fine locating and segmenting on the image; automatically identifying partial exercise answer images after segmentation; comparing identified answers with the standard answers and forming an automatic marking result; and preserving the automatic marking result, and sending the automatic marking result to a hardware device according to needs. The method separates answer sheets and blank paper, designs the answer sheets in the pattern meeting automatic processing requirements, can perform automatic calibration and segmentation even the images of answer sheets photographed by a mobile phone change a lot in position, shape and measuring scale, and does not need a scanner, thereby reducing requirements for an image collection device, and expanding the application scope of answer sheets.

Description

technical field [0001] The invention relates to the field of computer marking, in particular to a method and system for automatic processing and marking of handwritten answer sheets based on mobile phone photography. Background technique [0002] The existing computer marking system is based on computer network technology and image processing technology, combined with the experience of traditional manual marking for many years and modern high-tech, adopts the method of separating test paper and answer paper, objective questions are automatically graded by computer, subjective questions Different grading teachers grade the electronic images of candidates' answer sheets on the computer through the network, and finally the computer system automatically checks the marks and verifies the results. Computers generally cannot read handwritten answers to subjective questions. In the current computer marking method, the information collection of test papers usually scans each test pa...
