Range image generation apparatus, position and orientation measurement apparatus, range image processing apparatus, method of controlling range image generation apparatus, and storage medium

摘要

A range image generation apparatus includes: a generation unit adapted to generate a first range image of a target measurement object at one of a predetermined in-plane resolution and a predetermined depth-direction range resolving power; an extraction unit adapted to extract range information from the first range image generated by the generation unit; and a determination unit adapted to determine, as a parameter based on the range information extracted by the extraction unit, one of an in-plane resolution and a depth-direction range resolving power of a second range image to be generated by the generation unit, wherein the generation unit generates the second range image using the parameter determined by the determination unit.

1. A range image generation apparatus comprising:
a first generation unit configured to generate a first range image of a target measurement object at one of a predetermined in-plane resolution and a predetermined depth-direction resolving power by projecting a first pattern onto the target measurement object; an extraction unit configured to extract range information from the first range image generated by said first generation unit; a determination unit configured to determine, as a parameter based on the range information extracted by said extraction unit, at least one of an in-plane resolution and a depth-direction resolving power of a second range image; and a second generation unit configured to generate the second range image of the target measurement object by projecting a second pattern onto the target measurement object based on the determined parameter.
