英文摘要	The precise parameter calibration of the camera is the prerequisite for computer vision applications. A fully automatic camera calibration method based on projective transformation is proposed. A calibration board containing two kinds of circles is used to calibrate the camera. Firstly, perform threshold segmentation on the calibration image to obtain the area where the calibration board is located. Secondly, extract the circles on the calibration board and perform ellipse fitting to identify 5 large circles to determine the direction of the calibration board. Then, use the projective transformation to accurately sort all the circles to obtain a correspondence between the coordinates of the circles' center in the image and the known coordinates of the calibration board. Finally, use the image coordinate values of all the circles' centers to calibrate the camera parameters. The actual experiment verifies that the recognition method is fast, effective and accurate. The automatic calibration of the camera can be completed without manual intervention.
