Projector throws stable 1000fps image on a rough or moving surface

Dynaflash is a projector that maps a moving, deforming surface at 1000 frames per second, meaning that it can cast a stable image on it no matter how wild its gyrations. One caveat: it requires the target surface to have an invisible infrared grid on it.

Our method can obtain the deformation robustly at 1,000 fps by using an originally proposed marker "Deformable Dot Cluster Marker", even when the target causes large deformation and occlusions. Using these base technologies including DynaFlash and Deformable Dot Cluster Marker, we realize a new dynamic projection mapping onto deforming non-rigid surface. In this demonstration, by drawing the marker on the target with IR ink, we allow the marker to be invisible to human and enable robust sensing independently of the projected images. In our technology, both the projection and sensing are operated at a speed of 1,000 fps. Therefore, it is possible to keep the projection consistent with the deformation and extend the real world as if the projected image is printed or existed as an original (digital) texture on the target.
