Abstract

一种测距系统(901,902,903,904,905,1001)和车辆(106)，测距系统(901,902,903,904,905,1001)包括：扫描模块(200)和测距模块(203)；测距模块(203)用于向扫描模块(200)发射激光，并接收扫描模块(200)发送的反射光；扫描模块(200)包括：运动部件(201)和镜组(202)，运动部件(201)用于驱动镜组(202)扫描；镜组(202)还用于接收测距系统(901,902,903,904,905,1001)的环境中的被测物体(204)的反射光，并将反射光传输到测距模块(203)上。由此，扫描模块(200)和测距模块(203)分离设置，减小了扫描模块(200)的重量，使得运动部件(201)能够实现快速转动，提高了扫描效率。同时，测距模块(203)工作时不会随扫描模块(200)旋转，降低了测距模块(203)的电连接难度。
