Single-gun-camera-multi-dome-camera linkage method based on grid combination interpolation

Abstract

The invention provides a single- gun-camera-multi-dome-camera linkage method based on grid combination interpolation, which adopts a gun-camera-dome-camera linkage algorithm of the grid combination interpolation. The method comprises the following steps of step a, calibrating a gun camera scene: uniformly dividing a gun camera picture into m rows and n columns of grids and selecting four characteristic points in the grids to be calibrated; step b, acquiring a detection tracking result of a gun camera to be used as input; step c, acquiring deviation of a dome camera: judging a grid in which a target stays, selecting three adjacent characteristic points in the grid to be interpolated, and solving a deviation quantity of a steering target of the dome camera; and step d, controlling the dome camera: utilizing a three-dimensional positioning function in the control of a dome camera holder to control a steering target position of the dome camera so as to track a target. Due to the adoption of the method, the weaknesses that the dome camera tracking picture is discontinuous and the dome camera picture is fluttered can be overcome.

Description

technical field [0001] The present invention relates to the fields of video monitoring, video analysis, computer vision, pattern recognition, etc., and specifically relates to a single-armed-multi-ball machine linkage method based on grid-combined interpolation, which is particularly suitable for single-armed-multi-ball machine linkage Intelligent visual surveillance system (bolt camera refers to bullet camera, dome camera refers to dome camera). Background technique [0002] As an extremely effective means of modern management monitoring and security precautions, video surveillance has been widely used in various public places such as banks, stations, and office buildings. In recent years, due to the urgent need for public security and the continuous development of computer technology, visual monitoring is changing from traditional models to intelligent monitoring, and its related technologies have gradually become research hotspots in computer vision. Intelligent monitori...
