Fraunhofer research scientists have demonstrated a software driven projection system that will deliver sharp and undistorted images onto curved and even wavy surfaces. It’s been done before, but Fraunhofer’s concept is more efficient and a lot cheaper.

Planetariums and domed movie theatres are the obvious application, but the system could also find uses in advertising media such as event marketing. Previously impossible interiors can now be used for projection to deliver an immersive experience. Normally, images are generated by several projectors which have to be coordinated with each other in order to create a seamless total picture. The hardware is either adjusted manually or the projected images are electronically distorted so that they merge. Fraunhofer’s system automatically calibrates the projectors and superimposes the images producing perfectly synchronized projections on surfaces of any shape.

Digital cameras record the position of the images projected onto the screen. With the aid of image recognition algorithms, the individual images are then automatically distorted and adapted to the projection surface so that the many partial images produce a high-resolution, seamless total picture. The automatic calibration software works quickly and flexibly. Even if a projector slips out of position, its image can be very quickly re-inserted into the total picture.

The software can combine different media like movies and stills and can incorporate live action. So if you’ve ever wanted a multimedia show on an uneven and curved surface, here’s your answer.
