iPhone 的「第四颗摄像头」位置,为什么给了激光雷达?

爱范儿 · 2020-10-18
旗舰手机摄像头从 2016 年开始,以大约每年 1 个摄像头的数量在增长,有人调侃说麻将「八筒」将是所有智能手机摄像头的终极归宿 ... LiDAR 的全称是 Light Detection And Ranging,中文名激光雷达,是以发射激光束探测目标的位置、速度等特征量的雷达系统,由激光发射机、光学接收机、转台和信息处理系统等组成,可获得目标的距离、方位、高度、速度、姿态、甚至形状等参数,从而进行探测、跟踪和识别 ... 抛开专业术语,通俗理解 iPhone 12 上的 LiDAR,它就是一个能探测物体距离和记录深度信息的微型装置,和手机摄像头差不多大小。
