Optical measurement apparatus for three-dimensional measurement of object

摘要

The apparatus comprises a projector arrangement with at least two projection arrays, which projects a series of different light patterns on the object to be measured. Images of light patterns projected on the object are recorded by a camera, projection beams or light sections are determined from the produced images, and a surface contour of the object is calculated through a triangulation calculation. The apparatus comprises a projector arrangement with a projection axis and at least two projection arrays, which projects a series of different light patterns on the object to be measured. Images of light patterns projected on the object are recorded by a camera, projection beams or light sections are determined from the produced images, and a surface contour of the object is calculated through a triangulation calculation. The projection arrays are projected timewise separated by means of switchable light sources, whereby the projections of the individual light patterns belonging to a light code sequence are distributed evenly on the available projection arrays. The projection times of the projection arrays are cyclically arranged and are synchronized with the image recording of the camera, so that exactly one array is projected during the recording of a light pattern through the camera.
