Value, the region recognition of the first position numerical value maximum is human buttock；
The pressure value of the upper any continuous three pressure sensor detections of each row is added summation and draws second place number
Value, the region recognition of the second place numerical value maximum is shoulders of human body.
9. human body recognition methods according to claim 8, it is characterised in that further comprising the steps of：
Direction by the position between shoulders of human body and human buttock along shoulders of human body to human buttock is identified as the human body back of the body successively
Portion and human body waist.
10. human body recognition methods according to claim 8, it is characterised in that further comprising the steps of：
Identify that pressure sensor described in every row detects position of centre of gravity, and judge that often arranging the pressure sensor detects center of gravity
Position whether on the same line, if so, human body is then identified to lie low, if it is not, then identifying human body to lie on one's side.
