自由曲面立体物への簡単操作プロジェクションマッピングアプリ開発

In projection mapping on a three-dimensional object with a free-form curved surface, it is necessary to perform geometric correction of the projected video image pixel by pixel. The adjustment of the video image, including such correction, is extremely complicated and time-consuming, and it is a major burden on the creator. We have developed an application that can set up projection mapping in a short time with almost only mouse operations by integrating these series of tasks. This application enables accurate mapping of three-dimensional objects with free-form surfaces using an inexpensive projector and camera, without the use of special equipment. It can also be used in conjunction with commercially available video content creation applications.
