Dual-pixel sensors resolve 3D reconstruction scale ambiguity without reference objects

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called DP-SfM that can resolve scale ambiguity in 3D reconstruction using dual-pixel sensors. This technique leverages the defocus blur present in dual-pixel images to determine the absolute scale of a scene without needing a reference object of known size. The approach involves estimating the absolute scale and then optimizing the alignment of images by considering cross-view blur kernels, demonstrating effectiveness across various scenes and camera setups.

    DP-SfM: Dual-Pixel Structure-from-Motion without Scale Ambiguity

    arXiv:2605.01852v1 Announce Type: new Abstract: Multi-view 3D reconstruction, namely, structure-from-motion followed by multi-view stereo, is a fundamental component of 3D computer vision. In general, multi-view 3D reconstruction suffers from an unknown scale ambiguity unless a r…
