Camera Calibration with Accuracy Evaluation and Real-time Evaluation in the Use of Vision Robot

In order to calibrate a wide-angle camera in real-time and find the precious position of the target object which could help the robot to find to location where they are, new method which uses the center iteration method and the regional interpolation method based on the distortion correction table is proposed. With this method, the world coordinates of the target object could be calculated accurately. The experimental results show that the theory is effective enough to get the world coordinates of objects with good accuracy for industrial application.
