Stabilization of Floor Projection Image with Soft Unmanned Aerial Vehicle Projector

By mounting a projector on a soft unmanned aerial vehicle (UAV) called “S-CLOVD”, one can freely move and show visual information on the floor. One practical problem with the UAV-projector is the distortion of the projected image caused by UAV disturbance. In this paper, we propose a geometry-based method of stabilizing the floor projected image using the flight information of the UAV (e.g altitude, roll, pitch, yaw). By visual comparison of the stabilized images, its stabilization performance is shown much improved. In this paper, The UAV-projector system and stabilization algorithm are proposed. And, the performance of proposed idea is validated with experimental data.
