Abstract
A three-dimensional measurement apparatus comprises a detection unit configured to detect a plurality of intersection positions between first pattern light in which a bright part and a dark part are alternately arranged and second pattern light in which a phase of the first pattern light is shifted, by using tone values of a first image obtained by capturing a target object onto which the first pattern light is projected and tone values of a second image obtained by capturing the target object onto which the second pattern light is projected; and a measurement unit configured to calculate a third position based on a first intersection position included in the plurality of intersection positions and a second intersection position that is adjacent to the first intersection position and measure a three-dimensional position of the target object based on an interval between the third positions.
