Applied research of OpenCV-based camera calibration

Abstract

Camera calibration is one of the basic tasks in machine vision.Open source computer vision(OpenCV) library is introduced first,then camera model and coordinates transformation in camera calibration are given.Online real-time calibration and model-based point-objected relationship are used to calibration of the image,with distortion coefficients into consideration to achieve intrinsic and ex-trinsic parameters of the camera.The calibration result is used to measure the 3D object and experiment in the mobile robots platform.The analysis result validates feasibility of the calibration method.
