A new concept for 3-D shape measurement of complex ob- jects is proposed, which is based on photogrammetry and fringe projec- tion. The shape of a partial view is determined by a combination of the phase-shift method for fringe evaluation and a photogrammetric triangu- lation to calculate the 3-D coordinates related to the sensor coordinate system. For the measurement of complex objects, partial views are taken from different sensor positions. The problem of matching the par- tial views into each other is solved by transforming each sensor position and the relating point cloud of the shape in a global coordinate system by photogrammetric matching of reference targets. © 2000 Society of Photo- Optical Instrumentation Engineers.
