Large-area video fusion coverage method for vertical installation of single-row surveillance camera

Abstract

The invention discloses a large-area video fusion coverage method for vertical installation of a single-row surveillance camera, which is suitable for monitoring and covering areas of public securitykey prevention areas and large venues, assembly shops, airports and etc. The installation angle of the surveillance camera is regulated to achieve the improvement of the fusion effect of the surveillance camera. The rotated surveillance frame improves the vertical depth of a scene and enlarges the fusion coverage range to achieve the improvement of the final surveillance effect. The image alignment is performed through modes of two-dimensional video splicing or video fusion based on video projection / video image modeling to finally draw the large-scale image or achieve panoramic stitching. Thereasonable, intelligent and scientific management utilization of the surveillance camera at the key surveillance area is achieved.

Description

technical field [0001] The invention relates to the technical field of surveillance cameras and large-scene video fusion coverage, in particular to a large-scene video fusion coverage method in which a single-row surveillance camera rotates around its direction axis at a certain angle to achieve a vertical screen installation. Background technique [0002] As the whole society pays more and more attention to the security situation, surveillance cameras are widely used in all walks of life, especially in large workshops and key public security prevention areas, where they are widely used as real-time and effective supervision tools. At present, the surveillance camera is installed in the front direction to obtain a rectangular video with a wide horizontal direction and a narrow vertical direction. However, the current surveillance camera installation method is only suitable for close viewing of matrix video. When installing surveillance cameras in large places such as airport...

AI Technical Summary

Problems solved by technology

However, the current surveillance camera installation method is only suitable for close viewing of matrix video. When installing surveillance cameras in large places such as airports or installation workshops, it is impossible or inconvenient to install due to the longitudinal depth of field and the middle of each column due to reasons such as waiting seats or machine tools. Surveillance cameras, so the surveillance video obtained by daily installation has a large blind spot, which cannot meet the control needs of various surveillance, and the effect of surveillance and video fusion of large-scale scenes in the actual use process cannot be effectively satisfied
