ボール上への動的な2色の光線投影による卓球の演出方法

抄録

In recent years, a new way of staging sports is expected to make them even more exciting. However, most of the projected objects are static objects, and projection on high-speed objects is not so common. Lumipon projects a beam of light onto a ping-pong ball that moves at high speed while following the object by installing a laser on the same axis as the camera of a device called a saccade mirror that keeps the object in the center of the image. In this study, we added a ray of light of a different color to Lumipon, and the dynamic projection of the two colored rays creates a projection mapping-like effect on the ping-pong ball.
