The invention provides a human body detection device, the detection process of which includes: receiving the distance data s collected by the distance sensor t ; For the distance data s of the preset number m t Perform debugging and smoothing processing to obtain the first data group W, for the distance data s of the preset number m t Perform debugging to obtain the second data group W'; perform a fitting operation on the first data group W, and judge the change trend of the distance between the detected object and the distance sensor according to the fitting result; The detected object is in a static state; the fluctuation value of the second data set W' is calculated; when the fluctuation value is greater than a preset threshold, it is determined that the detected object is a human body. It can realize the detection of the human body in a static state, distinguish the standing human body from the stationary object, and eliminate the judgment interference caused by the stationary object in the original human body detection.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a human body detection device and method. Background technique [0002] Robotics is an emerging comprehensive discipline developed in recent decades. It has concentrated the latest research results of various disciplines such as mechanical engineering, electronic engineering, information science, automatic control, and artificial intelligence. It represents the highest achievement of current science and engineering. It is undoubtedly It is one of the most active research fields in the development of science and technology, among which service robots have been widely used. [0003] At present, service robots generally exist in all walks of life. In applications, there is often a need for human body detection. For example, by detecting whether there is currently a user, the current user's action or motion status and other human body information, the automatic opening / A series...
