Summary:The invention provides a fall detection method and device, electronic equipment and a storage medium, and relates to the technical field of data processing. The method comprises the following steps: acquiring a full-space point cloud of a to-be-detected space; performing feature extraction processing on the total space point cloud, and extracting a curvature feature vector corresponding to the total space point cloud; based on the curvature feature vector, carrying out segmentation processing on the full-space point cloud to obtain a human body point cloud; judging whether the to-be-detected space has a falling behavior or not according to the human body feature information; and when it is determined that the fall behavior exists in the to-be-detected space, sending fall information corresponding to the fall behavior to a user terminal. According to the embodiment of the invention, whether the human body falls down or not can be detected more accurately, the probability of falling down identification is impro
