Human Recognition Method Based on Stereo Vision and Infrared Imaging

Abstract

A human body recognition method based on stereo vision and infrared imaging is disclosed, including a processor, RAM, a first infrared imaging module and a second infrared imaging module, and the human body recognition method is set inside the processor, including the following steps: 1. Acquiring a scene Infrared image f 1 (x,y) and f 2 (x,y); 2. For f 1 (x, y) binarization processing to obtain a binary image I 0 (x,y); 3. to I 0 (x,y) corrosion operation to get the corrosion map I 1 (x,y); 4. to I 1 (x,y) expansion operation to get the expansion graph I 2 (x,y); 5. to I 2 (x,y) cyclic erosion until only the core point o is left j ; at I 1 In (x, y), use the image area pixel area calculation algorithm to get o j The pixel area of ​​the area s j ; 6. Calculate f 1 (x,y) and f 2 Parallax image d(x,y) of (x,y); 7. Core point o j The corresponding disparity d(x j ,y j ), and then calculate the distance D j ; 8. Calculate the imaging area S j 9. According to S j Size, to determine whether the imaging area may be a human body.

Description

technical field [0001] The invention relates to a human body recognition method based on stereo vision and infrared imaging, and belongs to the field of sensor detection. Background technique [0002] Human object detection has a very wide range of applications, such as intelligent monitoring, adjusting the angle of the camera according to the position of the human target to obtain the best monitoring effect, and smart home, adjusting the air outlet direction of the air conditioner or the heating device according to the position of the human target Heating direction to achieve the most comfortable effect. It can also control the start or stop of air conditioning equipment according to whether there are people in the environment to achieve the purpose of energy saving. However, at present, there are two main ways to detect human objects: the first is the human body infrared pyroelectric detection method, which can only detect dynamic human bodies, which has great limitations;...
