ESTIMATING DEPTHS IN A SCENE USING SINGLE-PHOTON DETECTORS AND BINARY STRUCTURED LIGHT PATTERNS
WARF: P220147US01
Inventors: Varun Sundar, Mohit Gupta
The Invention
UW researchers created a system comprised of single-photon detectors, such as single-photon avalanche diodes (SPADs), along with high-speed projectors that use digital micromirror devices (DMDs) for displaying binary patterns. They also developed novel coding schemes to captures and render the 3D images. The structured light encoding strategies use error-correction codes that enable robust decoding for Single-Photon structured light, even under large photon noise. This can provide fast and reliable 3D scanning of highly challenging objects (e.g., black tires and tubes, shiny and glossy metallic machine parts) that are considered impossible with conventional techniques.
