Early-warning method and device of building thrown-off object

Abstract

The invention relates to the field of community security monitoring and discloses an early-warning method of a building thrown-off object. The method comprises the steps of S1, camera installation andmonitoring image selection; S2, target intrusion detection; S3, verification of the building thrown-off object; and S4, early warning on the building thrown-off object. The invention further discloses an early-warning device of the building thrown-off object. The early-warning device comprises a front end, a background and an alarm device, wherein the front end comprises an image acquisition module, a target intrusion detection module and an image transmission module; the background comprises a building thrown-off object verification module, a video image storage module and a communication control module; and the alarm device comprises a signal receiving module and a voice-controlled alarm module. Through the early-warning method and device, the functions of advanced prevention and earlywarning are achieved, and a building thrown-off object detection technology is truly used for people; computing performance and hardware support problems brought by real-time and uninterrupted accurate discrimination of the building thrown-off object are avoided, and meanwhile a guarantee is provided for speed; and detection of garbage paper scraps, mineral water bottles, cigarette ends and othersmall targets among building thrown-off objects is well realized.

Description

technical field [0001] The invention relates to the field of community security monitoring, in particular to a high-altitude parabolic early warning method and device. Background technique [0002] At present, most of the high-altitude parabolic intelligent detection methods can only play the role of monitoring, detection and after-the-fact evidence collection. For example, a high-altitude parabolic height detection system and its correction system (public number: CN109163667A) can effectively calculate the high-altitude parabolic projection height. It is helpful to find the perpetrator; a high-altitude parabolic detection system and method based on computer vision (public number: CN109309811A) can analyze and process the acquired image data, determine the moving target in the image data, obtain the trajectory and obtain the high-altitude The throwing position of the parabolic target, and some methods of identifying the identity of the high-altitude parabolic through fingerp...

AI Technical Summary

Problems solved by technology

The above method is only an auxiliary technical means for obtaining evidence after the event of high-altitude parabolic objects, and cannot play the role of prevention and early warning of high-altitude parabolic objects. Therefore, the present invention proposes a method and device for early warning of high-altitude parabolic objects based on image processing and recognition technology.
