PROBLEM TO BE SOLVED: To provide an information processing apparatus capable of obtaining information that makes it possible to robustly measure a 3D shape of an object having a complicated shape.SOLUTION: A pattern having different luminance values depending on positions is projected onto a to-be-measured object 500, and an image is acquired by imaging the to-be-measured object onto which the pattern is projected. A detection line detected in the image is identified on the basis of a luminance changing depending on a position on a measurement line. A change in the luminance on the measurement line of the pattern used as a key can be extracted even when the detection line detected from the image is short, and an information amount per length of the measurement light is large, so that the measurement line of the pattern can be robustly identified even when the detected detection line is short.SELECTED DRAWING: Figure 2 |
