Structured-light, triangulation-based three-dimensional digitizer

摘要: The present invention provides a system for illuminating an object with special kind of structured light pattern, recording the shape reflected points by means camera, and, triangulation technique that does not depend on fixed direction source relative to reconstructing 3D through computer using data collected from reflection pattern. scanning is portable and require processing contemporaneous collection. stores in storage media several images objects different illumination patterns. subsequently processed, which applies routines, i.e., model building algorithms provide surface generation. acquisition according simplified acquiring only two or, optionally, four object, thereby significantly increasing digitization speed over laser-based scanners. projects both uniform same apparent source, allows numerical normalization images.
