Intelligent linkage and tracking method based on panorama camera and high speed ball-head camera

Abstract

The invention relates to an intelligent linkage and tracking method based on a panorama camera and a high speed ball-head camera and relates to the machine vision field. A camera parameter model and a characteristic point matching method are utilized to acquire a mapping relationship between a panorama image coordinate and a rotation angle of the high speed ball-head camera, and intelligent linkage of the panorama camera and the high speed ball-head camera is accomplished through the mapping relationship; for tracking of a panorama end, motion target detection is carried out through utilizing a frame difference method and a Surendra adaptive background update method, multi-target tracking of detected motion targets is carried out through a Kalman filtering algorithm and establishing a target matching matrix, and motion locus of the targets is acquired; an interested target is selected through a mouse, a high-speed ball is made through an intelligent linkage method to rapidly turn to a target region, the target is locked, and motion target detection is carried out through Kalman filtering and a Mean Shift algorithm. The method is advantaged in that global and local integrated monitoring, multi-target tracking and high definition snapshot are realized.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to an intelligent linkage and tracking method based on a panoramic camera and a high-speed dome camera. Background technique [0002] In the field of security, video surveillance, as an extremely important measure for social security prevention and control, is widely used in various fields such as finance, transportation, education, health, sports, energy, communications, public security, military and residential communities. At present, the application requirements of video surveillance are gradually developing from "visible" to "clear" and "wide". However, the monitoring capability of the monitoring system still needs a large distance from the monitoring requirements. In the monitoring, there are monitoring blind spots, inability to see the target clearly, and the response time is not fast enough, etc., which need to be solved urgently. [0003] Panoramic imaging technology can cap...

AI Technical Summary

Problems solved by technology

Due to the limited total resolution, the resolution of the panoramic camera is too low when observing local scenes, and cannot provide high-definition image information of the target, so its application range is severely limited

At the same time, when the key target is small in the monitoring field of view, the monitoring system cannot completely obtain the characteristic information of the target, and cannot capture and track it in high-definition

However, the high-speed dome camera can use its high-speed rotation and zoom function to realize high-definition shooting of any part of the scene, but the observation range of the high-speed dome is limited, and it cannot take into account multiple different scenes, so a single high-speed dome camera cannot meet the needs of investigation
