摘　　要：提出了一种基于单目视觉的车辆屏显式封闭驾驶舱前视视野重现方法。该方法通过准确的离线标定及在多线程并行框架下在线执行单目图像采集、前视图像处理和透视图像显示,可在显示屏上再现低失真度、高流畅度的前视画面。搭建了一套屏显式车辆封闭驾驶舱硬件系统,通过实验室和场地测试,从系统延时、前视视角、图像畸变、车辆高速直行、转弯、避障及驾车体验等方面验证了所提方法的有效性和高效性。该方法可为车辆封闭驾驶舱的后续改进提供良好的理论和实践基础。A monocular-vision-based method to reproduce the forward-looking visual field of the vehicle closed cockpit was proposed.Accurate off-line calibration and on-line monocular image acquisition,forward-looking image processing,and perspective image display are performed in a multi-threaded parallel framework.So forward-looking images can be reproduced with low distortion and high fluency on the screen.This paper also built a hardware system of vehicle screen-displayed closed cockpit.Through laboratory and field tests,the effectiveness and efficiency of our method are verified from the aspects of system delay,forward-looking angle of view,image distortion,high-speed straight driving,turning,obstacle avoidance and driving experience.This method provides a good theoretical and practical basis for the subsequent improvement of the vehicle closed cockpit.
