Title:
HUMAN BODY DETECTION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/085068
Kind Code:
A1
Abstract:
A human body detection device (100). A detection process of the human body detection device (100) comprises: receiving distance data st collected by a distance sensor (110) (S10); debugging and smoothing a preset amount of the distance data st, i.e., m pieces of the distance data st
, to obtain a first data group W, and debugging the m pieces of the distance data st to obtain a second data group W' (S20); performing a fitting operation on the first data group W, and determining a change trend of a distance between a detected object and the distance sensor (110) according to a fitting result (S30); when the change trend is constant, determining that the detected object is in a stationary state (S40); calculating a fluctuation value of the second data group W' (S50); and when the fluctuation value is greater than a preset threshold, determining that the detected object is a human body (S60). The human body detection device can detect a human body in the stationary state, distinguish a standing human body from a stationary object, and eliminate determination interference caused by the stationary object in original human body detection.
