Dynamic Depth-of-Field Projection for 3D Projection Mapping

This video introduces a dynamic depth-of-field projection system to realize a 3D projection mapping. The prototype included with a high-speed projector, a high-speed variable focus lens and a depth sensor. A comparison experiment showed that two fixed focus projectors were in the left and middle, and the projection became blurry when the board moved out of the focus. While, in the right, our dynamic projection was always in focus when the board moved from 0.5 to 2.0 meters. In the second experiment, v
