Flexible Optical 3D Non-Contact Coordinate Measurement 2003-01-1305

In today's industrial environment, there is a growing need for accurate, flexible, and user-friendly devices that provide 3-D measurements at high data acquisition rate while ensuring the highest possible data quality. Decreasing time-to-market goals has encouraged the development of optical 3-D digitizing and coordinate measuring systems using structured illumination or laser scanning techniques [1, 2]. Engineering applications now require the fast and accurate measurement of complex shapes and geometrical features using mobile 3-D sensors that can be adapted efficiently to objects of differing sizes without compromising flexibility, speed of acquisition, or accuracy. To fulfil these industrial demands, an advanced, high-resolution, and flexible 3-D sensor, the COMETVarioZoom, has been developed that is based on a fringe projection concept.
