Huakeng Ding, Yaowen Chen, Kun Zhou, Hongzhi Wu
Researchers at Zhejiang University and Hangzhou Research Institute of Holographic and AI Technology developed a differentiable framework for 4D structured light, enabling adaptive and simultaneous acquisition of 3D shape and reflectance. This approach uses uncertainty-driven optimization to tailor illumination patterns to specific objects, achieving up to a 100x reduction in exposure time and 2x faster total acquisition compared to prior 4D structured light techniques, while enhancing depth reconstruction accuracy.
Key insights
- On-the-fly, differentiable optimization of 4D spatial-angular structured illumination patterns can significantly improve both the efficiency and quality of combined shape and reflectance capture.
- An uncertainty-driven approach, where illumination patterns are optimized to reduce ambiguity in depth and reflectance estimates, allows for efficient information gain tailored to object specifics.
- Multiplexing multiple LEDs simultaneously in a 4D structured light system, rather than sequential single-LED illumination, drastically reduces exposure time and improves depth completeness, especially in shadow regions.
