Our method demonstrates effective recovery of geometry in 3D parametric scenes using limited depth measurements.

The method recovers the geometry of 3D parametric scenes from as few as 15 depth measurements, showing effectiveness in pose estimation.
Time-of-flight sensors provide low spatial resolution but capture detailed time-resolved data, allowing scene recovery from sparse measurements.
An analysis-by-synthesis approach with differentiable rendering refines scene parameter estimates, enhancing recovery accuracy.
Initial experiments highlight the method's capabilities and limits, showcasing potential for real-world applications in geometry recovery.

Sifferman et al. (2025) studied this question.
