Embodiment Construction
[0035] The invention will be described in further detail below in conjunction with the accompanying drawings.
[0036] The whole fisheye camera calibration system is as follows: figure 1 As shown, it contains three processing modules, which are distortion correction module, feature detection module and fisheye camera parameter calibration module.
[0037] (1) Distortion correction module: preprocess the image, mainly including distortion correction using the pinhole imaging contrast correction method; used to eliminate the distortion of the original fisheye image and reduce the calculation of the distortion coefficient in the fisheye camera parameter calibration module ;
[0038] (2) Feature detection module: quadrilateral fitting, Harris corner point detection; used to provide stable feature points, as the expected reference point in the fisheye camera parameter calibration module;
[0039] (3) Fisheye camera parameter calibration module: This module takes the theoretical i...
