Claim One:
1. A three-dimensional measurement apparatus comprising at least one processor coupled to at least one memory, the at least one processor executing instructions to: acquire an image including an object to which a pattern is projected, wherein the pattern includes a plurality of lines and in which a plurality of features on at least one line among the plurality of lines are arranged so that a maximum value of an interval between adjacent features on a same line is lower than two times of a minimum value of the interval between the adjacent features on the same line and the maximum value is greater than the minimum value; detect lines and features of the projected pattern in the acquired image; identify to which line of the plurality of lines of the pattern each of the detected features belongs based on positions of the detected features; and measure a three-dimensional shape of the object to which the pattern is projected based on an identification result.
