Student stand-up dual-system detection method and system

Abstract

The method discloses a dual system detection method for rising of students. A main camera for locating images and au auxiliary camera for detecting height are combined to judge the rising of students. According to the dual system detection method and system for rising of students, the dual system detection method is adopted, so that misidentification to lowering heads, rising heads, shaking hands and the like can be effectively eliminated, and identification accuracy is greatly improved.

Description

technical field [0001] The method discloses a video monitoring method, in particular a dual-system detection method for students standing up, and belongs to the technical field of educational video monitoring. Background technique [0002] With the continuous development of video surveillance technology, its application fields are becoming more and more extensive. At present, video surveillance technology is widely used in the field of education to monitor classroom order and classroom effects. Existing educational monitoring systems usually include teacher cameras for monitoring teachers and blackboards, as well as student cameras for monitoring students. With the development of monitoring technology, when students are being monitored, when students are answering questions or standing up for other reasons , the student camera will aim at the student who is standing up, and give it a close-up. In the prior art, a camera is used to analyze human behavior, that is, to locate w...

Problems solved by technology

Because the size of the classroom is different, the size of the person on the image is also different, so when the students do some small movements, such as lowering their heads and raising their heads, shaking their arms, etc., they may be mistaken for students standing up, resulting in detection errors
