Methods and systems for laser based real-time structured light depth extraction

摘要

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.
