Data processing method and device based on point cloud, equipment and medium

The invention discloses a data processing method and device based on point cloud, equipment and a medium, and relates to the technical field of detection and recognition. The data processing method based on point cloud comprises the steps of: determining target point cloud data according to obtained radar point cloud data; performing centroid extraction according to the target point cloud data toobtain target centroid data; determining whether a target object falls down or not according to the target centroid data; if the target object falls down, determining falling duration corresponding tothe target object; and when the falling duration reaches a preset alarm time threshold, sending alarm information corresponding to the target object. According to the invention, the problems of privacy leakage, high false alarm rate and the like in an existing traditional anti-falling detection scheme are solved, and the detection accuracy is improved. 本发明公开了一种基于点云的数据处理方法、装置、设备及介质，涉及检测识别技术领域，该基于点云的数据处理方法包括：依据获取到的雷达点云数据确定目
