The invention relates to a fisheye camera calibration method. The method comprises the following steps: firstly, carrying out feature region matching on an original image to obtain image coordinates of corresponding feature points; calculating a rough extrinsic parameter of the camera by using the image coordinate, and performing view angle transformation on a preset area of the original image according to the rough extrinsic parameter to obtain a transformed image; then, carrying out feature point detection on the transformation diagram to obtain the corresponding image coordinates; and calculating high-precision external parameters according to the image coordinates; and when the high-precision external parameter meets the evaluation requirement, confirming that calibration is successful and outputting the high-precision external parameter as a final external parameter. According to the fisheye camera calibration method, feature point detection is finally carried out on the transformation diagram and is not
