Seeing Around Corners With Dual Photography
“This project has absolutely blown my mind. Basically they photograph an object with the photosensor at one point, and the light projector at another, and use the Helmholtz reciprocity algorithm to virtually switch the locations of the camera and projector, showing exactly what the light source “sees”! If that doesn’t make sense to you, check out the research page and make sure to watch the 60MB video at the bottom. The playing card trick will leave you speechless!”
