High-altitude object throwing early-warning protection system based on target recognition and control method

Abstract

The invention discloses a high-altitude object throwing early-warning protection system based on target recognition and a control method. The system mainly comprises an image acquisition device, a recognition device and a projection device. The image acquisition device comprises a camera support, at least one upward camera and at least one downward camera. The projection device comprises an earlywarning device and a warning device. The recognition device comprises a recognition server, the upward camera and the downward camera are installed on the camera support, the upward camera faces floors of a residential building, the downward camera faces a pedestrian path below the residential building, the early warning device is installed on an outer side of a bottom layer of the residential building, and the warning device is installed on an upper portion of the camera support. The visual field ranges of the cameras are expanded through multi-view shooting, monitoring dead angles are avoided, meanwhile, the early warning device and the warning device are provided, and the real-time danger warning is achieved for pedestrians on a road and the warning is given to uncivilized residents under the condition that high-altitude object throwing happens.

Description

technical field [0001] The invention relates to the technical field of smart city monitoring, in particular to a high-altitude parabolic early warning and protection system and control method based on target recognition. Background technique [0002] In urban multi-storey residential buildings, it is not uncommon for a very small number of uncivilized residents to throw things out at will. The behavior of throwing objects at high altitudes is likely to cause casualties and property losses, and has become a major public nuisance. [0003] At present, some residential buildings are equipped with cameras, which are installed downstairs in the residential buildings and look up to shoot high-altitude parabolic behavior, which can play a role in evidence collection. However, due to the influence of the field of view of the camera, it is not easy to capture the pictures of the entire residential building. Some cameras use wide-angle lenses. Although they can capture the complete pi...

Problems solved by technology

However, due to the influence of the field of view of the camera, it is not easy to capture the pictures of the entire residential building. Some cameras use wide-angle lenses. Although they can capture the complete picture of the residential building, there is a distortion effect, and the pictures in some areas of the residential building cannot be viewed. Clear, or there is a monitoring dead angle

In addition, simple photographing and evidence collection is not enough to urge uncivilized residents to stop throwing objects at high altitudes, and it is impossible to provide early warning of high-altitude throwing objects to those passing by downstairs
