Abstract

An exemplary depth data generation system (“system”) accesses a first depth map and a second depth map of surfaces of objects included in a real-world scene. The first and second depth maps are captured independently from one another. The system converges the first and second depth maps into a converged depth map of the surfaces of the objects included in the real-world scene. More specifically, the converging comprises assigning a first confidence value to a first depth data point in the first depth map, assigning a second confidence value to a second depth data point in the second depth map, and generating a third depth data point representing a same particular physical point as the first and second depth data points based on the first and second confidence values and on at least one of the first depth data point and the second depth data point.
