Abstract
A depth sensing apparatus and an operation method thereof are provided. The depth sensing apparatus includes a projector, multiple cameras, and an image processing circuit. The projector includes a diffraction optical element (DoE) and a light source module. Rays of the light source module selectively pass through at least one of multiple projection style regions of the DoE so as to generate a projection pattern, and the projection pattern is projected to a field. The cameras respectively shoot the projection pattern projected to the field to obtain multiple images. The image processing circuit processes the images to obtain multiple depth maps. The image processing circuit at least merges the depth maps to generate a final depth map of the field.
