The application discloses a fall-down behavior detection method and device and a medium. The method comprises the steps that detection signals generated by a plurality of preset laser receiving devices in a detection area are acquired, wherein the detection signals are generated after the laser receiving devices receive lasers emitted by corresponding laser emitting devices, and the laser emittingdevices are preset in the detection area and correspond to the laser receiving devices one to one; and whether a detection object appearing in the detection area has a fall behavior is determined based on the detection signals. According to the embodiment of the invention, the falling behavior of a detection object is identified by analyzing the detection signal generated by the laser, and the accuracy of fall behavior detection is effectively improved.
Description
technical field [0001] The present application relates to the technical field of behavior detection, in particular to a fall behavior detection method, device and medium. Background technique [0002] In private scenes such as bathrooms, in order to ensure the safety of users, radar equipment or depth cameras are usually installed to monitor private scenes, collect user behavior data, and then use pre-built machine learning models to analyze the collected behavior data. Analysis to determine whether users in private places have fallen behavior. [0003] For the detection of the above-mentioned fall behavior, using machine learning analysis method, the accuracy rate is not high, and it is prone to missed detection or wrong detection, and through the monitoring of the camera, there is a risk of user privacy leakage, which makes it difficult for users to accept. Contents of the invention [0004] In view of the above-mentioned defects or deficiencies in the prior art, it is ...
