Time of the Flight of the Gaussians: Optimizing Depth Indirectly in Dynamic Radiance Fields
Problem: In continuous-wave time-of-flight (C-ToF) radiance field reconstruction, the property of interest—depth—is not directly measured, causing an additional challenge.
This problem has a large and underappreciated impact upon the optimization when using a fast primitive-based scene representation like 3D Gaussian splatting. This method is commonly used with multi-view data to produce satisfactory results, but it is brittle in its optimization otherwise.
Contributions: • A dynamic C-ToF GS method with 100× efficiency improvement in both optimization and rendering.
• An investigation into C-ToF radiance field optimization and the empirical biases critical for accurate reconstruction of C-ToF radiance fields.
