刚刚发布的苹果12系列里，被隆重介绍的LiDAR，是个什么东西呢？很多人以为，这就是个景深传感器，就是个TOF(time of flight)。但事实没有这么简单。LiDAR（Light Detection and Ranging）这是激光雷达的简称。它的功能我们用一个LiDAR生产商的gif来了解一下。对，就是通过激光进行测距，测速，测绘等。在功能上和其...
激光雷达(LiDAR)是光探测与测距(Light Detection and Ranging)技术的缩写。在工作过程中,激光束从光源发射并被场景中的物体反射回探测器,通过测量光束飞行时间(Time of Flight,简称ToF),可以推算出场景内物体的距离,并生成距离地图。目前,LiDAR已广泛应用于各个领域。在大气科学中,LiDAR被用于空气质量监测和污染物检测...

与雷达原理相似,激光雷达使用的技术是飞行时间(TOF, Time of Flight)。具体而言,就是根据激光遇到障碍物后的折返时间,计算目标与自己的相对距离。激光光束可以准确测量视场中物体轮廓边沿与设备间的相对距离,这些轮廓信息组成所谓的点云并绘制出3D环境地图,精度可达到厘米级别,从而提高测量精度。
TOF(Time of Flight) 即飞行时间，这一说法基本上已被更为准确的术语 LADAR 或比较常用的 LiDAR 所...

A range of approaches exist to directly measure distance as the length of the reflected optical path from laser, to a target where it is reflected, and back to a sensor. These are commonly known by various names, including LIDAR and time of flight sensors, although there is actually overlap...
