Three-dimensional measurement apparatus
 A three-dimensional measurement apparatus for measuring three-dimensional information of an object with high speed and high accuracy is disclosed. A laser light is converted to a collimated light, which forms a stripe of light on an object through a projection unit. The projection unit is moved back and forth by a linear motor along the collimated light in a direction perpendicular to the longitudinal direction of the stripe of light. Since the projection unit projects a light stripe of constant width on the object with constant reception of the collimated light, a plurality of stripes of light can be formed on the object by means of simple movement of the projection unit. The area on the object scanned by the plurality of stripes of light is captured by a CCD camera, and three-dimensional information is measured using the light-section method.
