Laser-based methods and systems for real-time structured light depth
extraction are disclosed. A laser light source (100) produces a
collimated beam of laser light. A pattern generator (102) generates
structured light patterns including a plurality of pixels. The beam of
laser light emanating from the laser light source (100) interacts with
the patterns to project the patterns onto the object of interest (118).
The patterns are reflected from the object of interest (118) and detected
using a high-speed, low-resolution detector (106). A broadband light
source (111) illuminates the object with broadband/light, and a separate
high-resolution, low-speed detector (108) detects broadband light
reflected from the object (118). A real-time structured light depth
extraction engine/controller (110) based on the transmitted and reflected
patterns and the reflected broadband light.
