A method, device, terminal device and storage medium for identifying a falling object

Abstract

The embodiment of the present invention discloses a falling object identification method, device, equipment and storage medium. The method includes: performing background difference between the video image frame of the surveillance video and the background image frame to obtain a plurality of binarized marked image frames , and according to each binarized marked image frame, the moving track image frame of the moving area is obtained; the moving track image frame of the moving area is input to the trained image classification model, so as to judge whether the moving track of the moving area is The trajectory of the falling object; if it is determined that the movement trajectory of the motion area is the trajectory of the falling object, then it is determined that there is a falling object in the surveillance video. The technical solution provided by the embodiments of the present invention realizes the effective monitoring of falling objects in the monitoring video, greatly improves the monitoring efficiency and timeliness of the falling objects, and at the same time reduces the false alarm detection rate of the falling objects in the monitoring video, The identification method has high robustness and universal applicability.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of monitoring, and in particular, to a method, device, terminal device, and storage medium for identifying a falling object. Background technique [0002] The continuous advancement of science and technology has made video surveillance technology widely used in social life. With more and more high-rise buildings rising on the ground, the effective monitoring of high-altitude falling objects has become an important technical means to ensure the safety of social life. [0003] In the existing monitoring scheme for high-altitude falling objects, by arranging cameras outside the building, real-time video recording is performed on the outer wall of the building, and the staff manually observes the front of the monitoring screen to monitor the behavior of high-altitude throwing objects. However, after the parabolic or falling behavior occurs, the relevant units such as the property or the...

[0004] However, such a monitoring method not only consumes a lot of labor costs, but also negative factors such as fatigue and environmental noise can easily lead to people's distraction, which poses a large safety hazard. After a throwing or falling object occurs, manual review Then there is greater passivity and hysteresis, unable to respond quickly to high-altitude parabolic behavior
