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

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.
