Operation method of self-positioning robot-based multi-camera parameter automatic calibration system

Abstract

The invention discloses an operation method of a self-positioning robot-based multi-camera parameter automatic calibration system. A self-positioning robot carrying a marker cruises and carries out self-positioning in an offline built environment map to obtain a world coordinate, and a main control computer acquires a camera image and processes the image to obtain an image coordinate of the marker; and the main control computer can automatically carry out the parameter calibration of cameras by combining the dot pair data of more than eight world coordinates and corresponding image coordinates. The operation method provided by the invention has the greatest characteristics of automatically carrying out the parameter calibration on multiple distributed and fixed cameras, greatly reducing labor calibration cost and improving the standardization and accuracy of a calibration process. The upgrading can be realized very conveniently based on the existing monitoring system, and an advanced intelligent algorithm applied to a monitoring and visual system is based on the results of camera calibration, therefore, the operation method provided by the invention has a very broad application and popularization prospect in monitoring systems in the future road traffic, office building corridors, factories, public security and the like.

Description

technical field [0001] The invention relates to an operation method of a multi-camera parameter automatic calibration system based on a self-positioning robot. Background technique [0002] In recent years, visual systems have become more and more popular in human production and life, and large-scale video surveillance systems are widely used in production process monitoring, factory building monitoring, community monitoring, public venue monitoring, road traffic monitoring and other fields. It also plays a major role in the security work of large-scale events such as the World Expo. It can be said that visual surveillance has almost spread in urban public places, and there will be more and more promotion and application in the future, and it will play a more important role. [0003] The current video surveillance system is still at a relatively elementary level of application. Although it can provide some practical functions such as license plate detection and moving objec...

Problems solved by technology

[0005] Now, although there are very mature algorithms and operation procedures for camera calibration, manual participation is required, such as making and placing calibration boards, setting the world coordinates of calibration points, etc., for large-scale visual monitoring with thousands of cameras at every turn. system, this workload is huge and error-prone
