High altitude parabolic detection system and method based on computer vision

Abstract

The invention discloses a high altitude parabolic detection system and method based on computer vision. The system comprises: video image collection unit used for comprehensive real-time monitoring ona community and obtaining image data; a network transmission unit used for transmitting the image data; a moving object detection unit used for receiving the image data from the network transmissionunit, and performing analysis processing on the obtained image data to determine a moving target in the image data; and a central processing unit used for tracking the moving target to obtain a feature and a movement trajectory of the moving target, judging whether the moving target belongs to high altitude parabolic, and obtaining a throwing position belonging to a high altitude parabolic target.The high altitude parabolic detection system relates to the field of community security and protection systems. The high altitude parabolic detection system disclosed by the invention has a wide application range, high versatility and a good detection effect.

Description

technical field [0001] The invention relates to the field of community security systems, in particular to a computer vision-based high-altitude parabolic detection system and method. Background technique [0002] High-altitude parabolic is called "the pain hanging over the city". The behavior of high-altitude parabolic has always been concerned. As an uncivilized behavior in the city, it also brings great social harm. Through scientific calculations and tests, from 12 Throwing a 30-gram egg on the body from a floor about 1 meter high can cause swelling, throwing it from about 54 meters can smash a person's skull, and throwing it from about 75 meters can cause death on the spot, causing irreparable damage. s damage. Due to the fact that this kind of uncivilized behavior is carried out on many high-altitude floors, there are few witnesses, and the throwing time is short. Some people even hide their shadows deliberately when throwing objects, making it difficult for law enforc...

AI Technical Summary

Problems solved by technology

[0003] At present, the supervision of high-altitude parabolic behavior mainly relies on irregular patrols organized by residents spontaneously and posting warning signs in areas where high-altitude parabolic objects often occur; however, the method of irregular patrols cannot completely monitor the behavior of high-altitude parabolic objects, and consumes a lot of manpower; The method of posting warning slogans is easy to be ignored, cannot attract enough attention, and has very limited effect
