摘　　要：针对乘用车在停车和启动时因空间不足、驾驶员视野狭小易发生擦碰的问题,设计一款新的全景泊车辅助系统,并通过全景泊车辅助系统模拟系统对全景泊车辅助系统中涉及的鱼眼摄像头标定及鱼眼图像畸变矫正、图像拼接等技术进行研究。该模拟系统仿照全景泊车辅助系统模拟平台前、后、左、右安装四个鱼眼摄像头,将平台周围四个不同方向的图像实时采集,并拼接成一幅全景图。实验结果表明:该模拟系统的全景图像无拼接缝隙,拼接时间减小了35%以上,鲁棒性强。A new panoramic parking aid system is designed to solve the problem of collision when the passenger car stops and starts because of the lack of space and the narrow vision of the driver.Through the simulation system of panoramic parking aid system,the technology of fish eye camera calibration,fish eye image distortion correction and image stitching in the panoramic parking aid system were studied.The simulation system imitated the panoramic parking assistant system and installed four fish eye cameras in the front,back,left and right of the simulation platform to collect and splice the images in four different directions around the platform into a panorama in real time.The experimental results show that the panoramic image of the simulation system had no splicing gap,and the splicing time was reduced by more than 35%and strong robustness.
