Abstract
A three-dimensional distance measurement apparatus comprising: a distance information calculation unit configured to calculate distance information of a measurement object based on a captured image of the measurement object on which pattern light is projected; and a local pattern setting unit configured to adaptively set a spatial resolution of measurement points of the pattern light for each local region, wherein the local pattern setting unit sets the spatial resolution of the measurement points of the pattern light based on information about an arithmetic amount of the distance information calculation unit.
