摘　　要：为解决光线经挡风玻璃折射导致的传统标定模型精度差的问题,根据光线折射规律和挡风玻璃姿态建立挡风玻璃的光线折射模型,开发一种前挡风玻璃后方前视相机的高精度标定新算法,并通过仿真试验和实车试验,证明新算法的标定精度显著提高。To solve the poor calibration accuracy of traditional camera models caused by light refraction through the windshield,the authors establish a light refraction model of the windshield according to the light refraction law and the windshield posture to develop a new high-precision calibration algorithm for the front-view camera behind the front windshield.The simulation tests and actual vehicle tests prove that the cali-bration accuracy of the new algorithm is markedly improved.
