Projector-Screen Matching Image Generation Technology for Spatial Augmented Reality

The technology used to distort any projected image to fit the uneven-shaped physical screens perfectly is a key issue to the application of Spatial Augmented Reality. We proposed an image generation technique based on Structured Light, which can generate the image of physical screen at the projector angle. Through the image, we thus get the accurate matching information between the projected image and the physical screen. It can be used as the initial image for people to debug remotely and conveniently on the worksite. This paper also confirmed the high stability and accuracy of the technology on different physical screens with different materials.
