发明名称 Structured light system
摘要 A structured light system based on a fast, linear array light modulator and an anamorphic optical system captures three-dimensional shape information at high rates and has strong resistance to interference from ambient light. A structured light system having a modulated light source offers improved signal to noise ratios. A wand permits single point detection of patterns in structured light systems.

主权项 1. A structured light system comprising: a light source that generates light; a linear array spatial light modulator that modulates light from the light source to create line images, the modulator operating at a reference frequency; an anamorphic optical system that spreads the line images into a two-dimensional spatial pattern having variations in only one direction, the pattern being characterized by a spatial phase; and, a camera that demodulates the spatial phase of the pattern by sampling the pattern synchronously with the reference frequency, wherein the camera has a frame rate and a sampling rate, the sampling rate is the same as the reference frequency, and the reference frequency is three times greater than the frame rate.
