LiDAR is a type of depth sensor and 3D scanning technology that measures the distance between a sensor and its surroundings with laser pulses. This generates a 3D map for augmented reality. LiDAR stands for Light Detection and Ranging.

A LiDAR device emits invisible laser pulses, and it measures the time it takes for the pulses to return to calculate distance. This will create a detailed depth map that allows humans and computers to understand surfaces, planes, and the boundaries of your environment.

An iPhone Pro user uses LiDAR to scan their space to quickly detect floors and walls, so that 3D models can be placed instantly within apps like Trace.

LiDAR improves device tracking and stability and reduces drift. Occlusion, meshing, and overall realism in augmented reality is more effective with this technology.
