The embodiment of the invention discloses a method of collecting answer information of an answer sheet. The method comprises the steps as follows: acquiring an answer sheet image comprising an initial non-answer area; selecting at least one pixel point in the non-answer area as a seed pixel point to be placed into a set; when the color of the seed pixel point in the set is a non-default color, filling the color to be a first default color, when an adjacent pixel point of the seed pixel point is non-default colored, filling the color of the adjacent pixel point to be the default color, removing the seed pixel point, and taking the adjacent pixel point as a new seed pixel point to be placed into the set, and executing the judging steps again until the set is empty; determining the area surrounded by the pixel point in the default color as an answer area; and identifying filling information in the answer area so as to determine answer information of the answer sheet. The invention further discloses a device of collecting answer information of the answer sheet. According to the embodiment of the invention, cost can be reduced, convenience is provided for examinees, and identification accuracy and efficiency are improved.
Description
technical field [0001] The present application relates to the technical field of information processing, in particular to a method for collecting answer information of an answer sheet and a corresponding device thereof. Background technique [0002] With the development of information technology, the collection of answer information in a certain scale of examination has changed from traditional manual identification to electronic processing. For example, answer sheets are designed in the form of standard answer sheets, and candidates use specific tools such as pencils. Fill in the candidate answer area, and then identify the filled area by electronic means, so as to determine the answer information on the answer sheet. This electronic method of collecting answer information greatly improves work efficiency. [0003] In the prior art, a commonly used electronic means is to use an cursor reader (OMR) to collect answer sheet information. In order to ensure the normal operation...
