In order to make a movable display projecting onto high-rise walls or arbitrary objects in physical space as a digital signage, a system, called a drone-projector, has been investigated with a beam projector mounted on a drone. The vibration during hovering caused by the motors of propellers in the drone brings distortion in the projected image. In this paper, we extend an existing sensor-based stabilization method by compensating different scaling of the projected image due to different distance of the drone-projector to the projected surface. Our experimental results show that the distortion of the projected image is made much attenuated by using the proposed stabilization method.
