Abstract

Recently, luminance compensation that realizes image projection canceling the in uence of patterned projection surfaces, has attract attention. This technique can cancel the in uence of the patterns, based on the response function representing the input-output relationship between a projector and a camera. On the other hand, it largely depends on the inter-pixel correspondence between the projector and the camera, so projection surfaces is limited to a rigid body. That is, the utilization area of luminance compensation is largely limited. In this research, we realize luminance compensation on swinging curtains by estimating the inter-pixel correspondence in real-time. In addition, the GPU is used to execute the system in real-time. We examine the effectiveness of the constructed system, using curtains of various materials.
