激光雷达是一种集激光、全球定位系统与惯性导航系统三大技术于一身的综合光探测与测量系统,其工作原理是通过透镜、激光发射及接收装置,基于激光飞行时间(TOF:time of fly)原理获得目标物体位置、移动速度等特征数据,并且获得的数据本身就是三维数据,不需要通过大量运算和处理才生成目标三维图像,激光测距有非常高的精度。所以,激光三维成像雷达是目前能获取大范围三维场景图像效率最高的传感器,也是目前能获取三维场景精度最高的传感器。
丰田汽车研究所在相当长的一段时间里一直在发展自动驾驶技术,在今年早些时候的国际消费电子展(CES)上还推出了Level 3版本的自主驾驶系统。Level 3系统能够使用传感器(如激光雷达)来监控环境,但司机仍需坐在驾驶位上关注着路面状况。这家新公司可能会让丰田实现技术超越从而加速实现完全自动驾驶的目标。
