Dynaflash is a projector that maps a moving and deformed surface at 1000 frames per second. In practice, it can project an always stable image onto any surface, no matter how much it moves.
Have you ever seen a 1000fps projector capable of sending images that move perfectly in sync on a flag in the wind? It's quicker to show you Dynaflash than to explain it, and in fact I'll show it to you, then we'll think about it a bit:
The project was born inIshikawa Watanabe Lab, a facility of the University of Tokyo that deals with researching and applying new technologies: this is one of his most successful and promising projects.
The secret? An infrared grill
From the presentation of the research I learn that the crux of all technology lies in a tool that can also be used successfully in other fields. The image transmitted by the projector remains non-deformable, adapting at incredible speed because it is literally "modelled" on an invisible infrared grid which is used as a base.
1000fps, a faster projector than reality
Thanks to this "infrared electronic viewfinder", the method developed by the team is able to obtain the "adaptive" deformation of the image at a speed of 1.000 fps, a thousand frames per second even when the plane on which it is projected changes abruptly and quickly.
Using these two technologies already patented by the Laboratory, DynaFlash and Deformable Dot Cluster Marker, a new dynamic mapping for the 1000fps projector is obtained on a non-rigid deformable surface.
A shirt, a flag, a house facade, any fixed or mobile object that is 'marked' by infrared can accommodate non-deformable images. Any part of tangible reality can form a basis for advanced augmented reality projects.
Objects "painted" with changing textures, images and colors could become commonly used in a few years also thanks to this technology.
