Researchers have developed a new method called DP-SfM that can perform 3D reconstruction from dual-pixel sensor images without needing a reference object of known size. This technique leverages the defocus blur present in dual-pixel images to resolve the scale ambiguity typically found in multi-view 3D reconstruction. The proposed approach involves a linear method for estimating absolute scale followed by an optimization stage to align images, and has shown effectiveness across various scenes and cameras. AI
