Simple Measurement of Mask and Curved Surface Shape for Projection Mapping and Real Time Correction by FPGA

Abstract

In the projection mapping, it is necessary to deform the image according to the surface shape of the three-dimensional object which is a screen. In this research, we developed a method to detect corrected coordinates of all pixels on a simple system using Web camera and projector scanning line. In this paper, we describe this correction method and an example of real time image deformation realized by using the obtained correction coordinates and FPGA.
