Summary:PROBLEM TO BE SOLVED: To provide an image calibrating method of a panoramic fish-eye camera.SOLUTION: An image calibrating, stitching and depth rebuilding method of a fish-eye camera is provided that comprises the steps of: establishing a panoramic optical target space; using the panoramic fish-eye camera for shooting the panoramic optical target space's panoramic image; establishing a depth calibration parameter by using a depth calibration module; establishing an internal calibration parameter of the panoramic fish-eye camera; establishing an image stitching parameter and a space depth transformation parameter of the panoramic image and the panoramic optical target space; and using the internal calibration parameter, the image stitching parameter, the space depth transformation parameter and the depth calibration parameter to calibrate the panoramic image for generating a 3D panoramic image. The calibration parameters is optimized by accumulating all the camera parameters and executing a machine learning for increasing the computing efficiency.SELECTED DRAWING: Figure 1 【課題】パノラマ魚眼カメラの画像較正方法を提供する。【解決手段】パノラマ光学ターゲット空間を確立するステップと、パノラマ魚眼カメラを利用して、パノラマ光学ターゲット空間のパノラマ画像を撮影するステップと、深さ較正モジュールを使用することによって深さ較正パラメータを確立するステップと、パノラマ魚眼カメラの内部較正パラメータを確立するステップと、パノラマ画像およびパノラマ光学ターゲット空間の画像スティッチパラメータおよび空間深さ変換パラメータを確立するステップならびに内部較正パラメータ、画像スティッチパラメータ、空間深さ変換パラメータおよび深さ較正パラメータを使用して、パノラマ画像を較正して、３Ｄパノラマ画像を生成するステップを含む。すべてのカメラパラメータを蓄積し、計算効率を高めるための機械学習を実行することによって、較正パラメータを最適化する。【選択図】図１
