Abstract
Due to the problem that distortion exist for panoramic image stitching in terms of vehicle panoramic system, the research on image preprocessing for panoramic system was carried out. Firstly, the principal of vehicle panoramic vision was analyzed and the fundamental role that image preprocessing procedure plays in panoramic vision is found out. And then, the camera was calibrated with Hyperboloid model and the correction for distorted image is realized. Oriented by panoramic system, the effect of mounting position was taken into consideration for image correction and the suggested angle of camera installation for different mounting position is given. Through analyzing the existing problem of bird-eye image, a method of transforming twice with calibration plates is proposed. Experiment results indicate that the proposed method can weaken the existing problem of bird-eye image effectively and it can contribute to reduce the distortion in terms of image stitching for panoramic system.
