【摘要】：为了提高无人驾驶汽车对中远距离车辆目标的识别准确率,满足无人驾驶汽车对前方预瞄距离的要求,通过理论计算以及光学设计软件ZEMAX-EE,研究设计了一款适合安装于乘用车上的中远距离车载镜头。为了满足车载镜头在实际使用过程中对成像范围的要求,利用成像景深公式计算了对准距离为无穷远时,不同入瞳直径对应的成像范围,从而确定了满足实际使用条件、易于设计和检验的镜头参数设计方案。车载镜头的焦距为40mm,视场角为8.6°,入瞳直径为7mm,景深为30m~+∞,系统总长小于38mm。仿真分析结果表明,所设计车载镜头具有良好的成像质量,能够满足实际的使用要求。
[Abstract]:In order to improve the accuracy of vehicle target recognition for medium and long distance vehicles, and to meet the requirement of preview distance in front of driverless vehicles, theoretical calculation and optical design software ZEMAX-EE, are used. In this paper, a long-distance vehicle lens suitable for passenger cars is designed. In order to meet the requirements of imaging range of vehicle lens in practical use, the imaging range corresponding to different entrance pupil diameters when the alignment distance is infinite is calculated by using the imaging depth formula, and the practical application conditions are determined. Easy to design and test the design of lens parameters. The lens has a focal length of 40 mm, a field of view angle of 8.6 掳, a pupil diameter of 7 mm and a depth of field of 30 m ~ 鈭，
