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.
