- W2746706152 abstract "Aiming at the complexity of current fisheye camera calibration procedures, a study on fast fisheye camera calibration method is carried out in this paper. A stereoscopic calibration board is designed, which comprises three chessboards with red boundaries. After image segmentation according to the planes that different chessboard zones belong to, and running corner detection on each part separately, mapping between 2D image coordinates and 3D world coordinates is achieved. Based on a catadioptric imaging model, a method is introduced to calculate the pa?rameters for stereoscopic calibration. Experiments are conducted to compare this stereoscopic calibration with usual plane?multi?image calibration. The calibration accuracy is evaluated by results of distortion correction and the accu?racy of projection from image coordinates to world coordinates. Results indicate that stereoscopic calibration has the same accuracy as that of plane?multi?images calibration and has even greater robustness. Moreover, stereoscopic calibration simplifies the calibration process and shortens the time involved to a great extent." @default.
