Abstract: 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 calibration accuracy of the new algorithm is markedly improved.
Key words: front windshield; front-view camera; camera calibration; optical model
