Aerial Display Method Using a Flying Screen with an IR Marker and Long Range Dynamic Projection Mapping

Our group proposed a method of aerial display using a flying screen suspended from a drone and dynamic projection mapping on the screen. In this study, we propose two methods as extensions of this previous study. First, we propose a structure of a large screen with a specially designed LED marker. The proposed screen structure is suitable for suspending from a drone. The LED marker has a special structure that allows the screen center position to be estimated from the captured image. Successful and stable projection of laser patterns onto the screen prototype suspended from a flying drone was demonstrated. In this experiment the distance between the screen and the projection system was approximately 16 m. Second, we propose a method that enables long range dynamic projection mapping using a high-brightness projector. Stable projection of an animation of a 2D character on a manually moving screen approximately 16 meters away from the projection system was also successfully demonstrated.
