Abstract

A control method of a depth camera includes controlling first and second image sensors to detect light in a first wavelength range, generating a first depth map based on first and second images, subjecting one of the first and second images to edge-detection processing, controlling a light source to emit light in a second wavelength range when a number of edge pixels is determined to be smaller than a preset pixel number, controlling the second image sensor to detect light in the second wavelength range, generating a second depth map based on a third image, subjecting the first and the second depth maps to image fusion processing, and registering a fused depth map with one of the first and second images to generate 3D point cloud data.
