  author={Shaoxiong Wang and Y. She and Branden Romero and E. Adelson},
Vision-based tactile sensors have the potential to provide important contact geometry to localize the objective with visual occlusion. However, it is challenging to measure highresolution 3D contact geometry for a compact robot finger, to simultaneously meet optical and mechanical constraints. In this work, we present the GelSight Wedge sensor, which is optimized to have a compact shape for robot fingers, while achieving highresolution 3D reconstruction. We evaluate the 3D reconstruction under… Expand
