Sound & Video Contractor: Projection mapping applications typically take place either outdoors at night, or in very dim environments. This is because any ambient light washes out the projection, an issue that researchers have tackled with the addition of an illumination device that combines an LED panel with a lens array.

This technology seems really interesting, but is definitely early in the research phase. I think that the idea of using a camera to evaluate what the scene looks like, and adjusting the image to match is really interesting. I also found the use of aperiodic lenses really interesting, because I had never see them before. It is interesting to see the algorithm used to figure out how to place the lenses in a way that gives even levels of illumination over the whole projection surface.
While this worked very well for projection mapping onto a small surface in a lab, I don’t understand how this is going to expand to projection map on the scale of buildings or production, which it seems like is the goal. Currently, the projection panel itself is the same size as the projection surface, which is not at all practical at a larger scale. I also have questions about how the lenses will respond to varying throw distances, because I believe that the aperiodic lensing is specifically calibrated for this projection distance.
