Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] see figure 1 , a high-altitude parabolic early warning method, the main process and steps are as follows:

[0035] S1. Camera installation and monitoring image selection

[0036] According to the free fall motion formula of an object:

[0037]

[0038] Among them, h represents height, g=9.8m / s represents gravitational acceleration, and t represents time. According to formula (1), it can be concluded that:

[0039]

[0040] According to formula...

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...
