New research improves 3D surface measurement with advanced profilometry techniques

Two new research papers explore advancements in fringe projection profilometry, a technique used for 3D surface measurement. The first paper, "Diagnosing and Repairing Shape-Prior Shortcuts in Long-Range Single-Shot Fringe Projection Profilometry," introduces PhiCalNet, an architecture that significantly improves accuracy in long-range measurements by addressing shape-prior shortcuts. The second paper, "Contact-Based Fringe Projection Profilometry for High-Resolution 3-D Surface Measurement of Reflective and Transparent Objects," presents a contact-based method that enhances depth precision for complex surfaces, offering an improvement over existing GelSight sensors.
