Target recognition method, target recognition device and computer storage medium

The invention discloses a target recognition method, a target recognition device and a computer storage medium. The target recognition method comprises the steps of obtaining a radar signal of an area where a target is located; a three-dimensional point cloud is generated based on the radar signal, and each data point in the three-dimensional point cloud comprises radar intensity information; and extracting a target point cloud from the three-dimensional point cloud, and analyzing the behavior of the target based on the radar intensity information distribution of the target point cloud. According to the target recognition device, the radar sensor is used for physically obtaining the distance direction information, and the accuracy is high; echo information of the radar sensor has the advantages that a mainstream visible light scheme does not have, and more effective information such as vital signs and polar distance can be extracted from the echo distance; by constructing the two-dimensional feature matrix, t
