Abstract :
In this paper, we focus on camera calibration problem of circular markers. We propose the iterative method to calculate the coordinates of tangency points, and then get the camera parameters due to the imaging model. To reduce the error, we preprocess the original image using loG edge Detection. At last, we simulate and test this method. The results show that the method has a higher accuracy.
