The present invention provides an image calibrating, composing and depth rebuilding method of a panoramic fish-eye camera comprising the following steps of: establishing a panoramic optical targeting space; using the panoramic fish-eye camera for shooting the panoramic optical targeting space's panoramic image; establishing a internal parameter calibrating model for the panoramic fish-eye camera; establishing a image stitching parameter model and a space depth transforming parameter model of the panoramic image and the panoramic optical targeting space; and using the internal parameter calibrating model, the image stitching model, the depth transforming parameter model to calibrate the panoramic image for generating a 3D panoramic image. Compared to the prior art, the present invention can optimize the calibrating parameters by accumulating all the camera data and executing machine learning for increasing computing efficiency. 本发明提供种全景鱼眼相机影像校正、合成与景深重建方法，其包含有以下步骤：建立全景光学标靶空间；利用全景鱼眼相机拍摄全景光学标靶空间的全景影像；建立鱼眼相机的内部校正参
