The Invention
UW-Madison researchers developed a novel Time of Flight (ToF) imaging method for dynamic scenes, with the goal of simultaneously estimating 3D geometry, intensity, and 3D motion using a single indirect ToF (I-ToF) camera. The key observation is that 3D motion, as well as motion artifact-free depth and intensity, can be estimated by designing optical-flow-like algorithms that operate on coded correlation images captured by an I-ToF camera. Through the integration of a multi-frequency I-ToF approach with burst imaging, this yields high-quality all-in-one (3D geometry, intensity, 3D motion) imaging even in challenging low signal-to-noise ratio scenarios.
