The invention discloses a curved surface projection method of a multi-camera panorama system. The method comprises the following steps: obtaining a distortion image of a wide-angled camera; carrying out distortion adjusting to the distortion image and generating a distortionless image; and projecting the distortionless image to a three-dimensional surface and generating a panoramic image. According to the curved surface projection method of the multi-camera panorama system, the distortionless image is firstly obtained through distortion adjusting, and then a three-dimensional surface model is built, and moreover, coordinate transformation is unified according to the coordinate value Zc of Z-axis of the three-dimensional surface model. Finally, the distortionless image is projected to the three-dimensional curved surface model, and panoramic imaging on the surface is achieved. Compared with the prior panoramic imaging technique, the curved surface projection method of the multi-camera panorama system has the advantages that scene has a third dimension sense and is relatively real when the scene is looked; effective range displayed is greatly enlarged; and shape and outline of an three-dimensional object can be figured out when the object is projected to the curved surface, and problem of vagueness when the three-dimensional object is projected to the flat surface is effectively solved.
