A depth sensor is a type of camera that measures the distance between a device and real-world objects all around them to build a 3D map and mesh of a space.

Depth sensors can use structured light, LiDAR, or time-of-flight techniques to capture depth and distance information. This data helps to detect surfaces, boundaries of objects, and it also supports accurate occlusion and collision for 3D models.

A user wants to put AR furniture in every room of their house. They use the depth sensor to scan the space, which helps to make a mesh of the space. Once they place 3D models of the furniture, the mesh that was created allows their furniture to cast shadows on the ground, get occluded by the walls, and fit snugly into the real physical environment.

Depth Sensing is a core technology for augmented reality that improves realism, tracking, and object placement for any environment.
