According to the existing difficulties of parameter adjustment in taking pictures and the problems of how to keep two cameras cooperating coordination and coherence in the existing3D-camera,this paper presents an automatic acquisition method of stereo shooting parameters based on sterescopic vision. The method makes full use of the ability of panoramic3D-camera made of four Omnidirectional Vision Sensors(ODVS)to obtain panoramic stereo images and get the desired convergence point,distance,focal length,aperture factor and other parameters automatically through ThreeDimensional(3D)image processing technology. Experimental results show that the proposed method can effectively guarantee consistency of the3 D photographic parameters of focal length,shooting direction,shooting angle,3D depth and so on,solve the coordinating difficulties of two cameras' shooting action and the adjustment of3 D depth parameters during3 D shooting,achieve capturing3 D panoramic video and3 D close-up video and shooting3 D close-up video automatically by panoramic points controlled on the monitor at the same time.
