Description

Technical Field

[0001] The present invention relates to the field of intelligent monitoring, and in particular to a high-altitude object dropping monitoring system with full-viewing angle inspection. Background Art

[0002] Throwing objects from high places is an uncivilized behavior and will bring great social harm to the society. Difficulties in discovery, evidence collection, accountability, and low cost of violating the law have made throwing objects from high places one of the difficulties in community management, also known as the "pain hanging over the city".

[0003] The existing method to solve the problem of high-altitude object dropping detection mainly uses motion detection technology on the camera. When an object moves in the video, a high-altitude object dropping warning event will be triggered. This method has great disadvantages: the fluttering of clothes hanging on the balcony of the building, the change of ambient light, and the noise of the camera itself can easily be misreported as high-altitude object dropping events by motion detection, resulting in a large number of false alarms, which greatly interferes with the normal work of managers. In addition, the monitoring equipment is generally installed on the first floor. For high-rise buildings, it is difficult for the monitoring equipment to obtain a clear picture of the higher floors, that is, the obtained running trajectory is not complete, which requires fitting the running trajectory. The throwing point obtained by fitting is not accurate, and can only be approximately obtained. The position of the throwing point is not convenient for direct tracing. In addition, the existing camera is placed on an outdoor mounting frame, which is not convenient for full-view monitoring of the floor, resulting in subsequent tracing after the high-altitude object dropping occurs.

It is best to compare the comparison pictures through the throwing point comparison unit to compare the starting point of the trajectory and the starting point of the high-altitude objects thrown to see whether the error exceeds the error value. If not, the parabola point is determined. If it exceeds the error value, the approximate area is obtained.

The specific parameters of the adjustment can be determined according to the actual situation.
