Embodiment Construction
[0034] In this embodiment, four Hikvision EZVIZ C6H PTZ network surveillance cameras are used together with the Hikvision EZVIZ N1W hard disk video recording host (1TB, which can support 8 network surveillance cameras at the same time) for video shooting. Taking 4 cameras as an example (equivalent to 8 cameras in a circle) and heart rate detection as an example, the present invention will be further described in conjunction with the accompanying drawings and specific implementation.
[0035] like figure 1 As shown, a seamless detection method based on multi-camera non-contact vital sign parameters is carried out as follows:
[0036] Step 1: Use P cameras to obtain I frames of human upper body images respectively, and record the I frames of human upper body images obtained by any p-th camera as F (p) =[f 1 (p) , f 2 (p) ,..., f i (p) ,..., f I (p) ], f i (p) Indicates the i-th frame of the upper body image of the human body captured by the p-th camera, i=1, 2,..., I,...
