Abstract:
1. A three-dimensional measurement apparatus for calculating three-dimensional shape information of a target object based on a reflected pattern of a pattern which is projected onto the target object and is reflected by the target object, comprising: an obtaining unit configured to obtain a reflected pattern of a stripe pattern formed by alternately arranging a bright portion and a dark portion as first image data, and obtain the reflected pattern of a reversed stripe pattern formed by reversing the bright portion and the dark portion of the stripe pattern as second image data; a determining unit configured to determine a boundary position between the bright portion and the dark portion based on the first image data and the second image data; and a reliability obtaining unit configured to obtain a reliability indicating accuracy of the boundary position based on a first pixel value included in the first image data and a second pixel value included in second image data.
