摘　　要：针对汽车乘员舱飞行时间(TOF)相机可视角度小、无法兼顾前排所有成员等问题,提出一种TOF相机设计方案,通过热设计仿真的方式解决了TOF相机的散热问题,并通过对TOF相机镜头的光学设计与仿真,有效扩大了相机的视场角(FOV),同时进行了完整的设计验证试验,结果表明,该系统完整实现了TOF相机的功能,并可以大角度视场覆盖车内前排乘员,且满足车规级性能要求。Current Time Of Flight(TOF)camera products have problems such as small viewing angle,and inability to consider all passengers in the front row.To address this issue,this article proposed a design method for TOF cameras,which solved the heat dissipation problem through thermal design simulation,and effectively expanded the camera’s Field Of View(FOV)through optical design and simulation of the TOF camera lens.At the same time,a complete design verification test was conducted to verify the performance of the TOF camera product.The results show that the system fully realizes the functions of the TOF camera,cover the passengers in the front row with a large FOV,and meets the performance requirements of the automotive grade.
