ROBUST STEREO DEPTH SYSTEM

摘要

The subject disclosure is directed towards a high resolution, high frame rate, robust stereo depth system. The system provides depth data in varying conditions based upon stereo matching of images, including actively illuminated IR images in some implementations. A clean IR or RGB image may be captured and used with any other captured images in some implementations. Clean IR images may be obtained by using a notch filter to filter out the active illumination pattern. IR stereo cameras, a projector, broad spectrum IR LEDs and one or more other cameras may be incorporated into a single device, which may also include image processing components to internally compute depth data in the device for subsequent output.

1. A system comprising, one or more infrared (IR) cameras configured to capture one or more images of a scene illuminated with structured light, and a projector configured to output a structured light illumination pattern at an IR frequency or frequencies that are capable of being filtered out by a notch filter while being sensed by the one or more IR cameras.
