Three-dimensional measuring apparatus

A three-dimensional measuring apparatus comprising:

• a projection unit configured to project a predetermined fringe pattern on a measurement target region;
• an imaging unit configured to capture a measurement target object disposed in the measurement target region on which the predetermined fringe pattern is projected;
• a measuring unit configured to measure a three-dimensional shape of the measurement target object captured by the imaging unit;
• and
• a control unit configured to control the projection unit, wherein
• the predetermined fringe pattern includes a plurality of fringe regions that are disposed along a first direction, and each of the plurality of fringe regions changes in luminance in the first direction at a predetermined ratio and does not change in luminance in a second direction orthogonal to the first direction,
• the imaging unit includes an imaging device configured to output event data including two-dimensional point data that identifies a position of a pixel subjected to a luminance change when light is received, and
• the measuring unit measures the three-dimensional shape of the measurement target object by a light section method on a basis of positions of a plurality of pixels identified from pieces of the event data output in an identical time slot within unit time within which the imaging unit performs capturing.
