In this paper, we propose a method for calculating model parameters for fast stabilizing a moving projection display mounted on a flying drone. The projected image by the drone-projector system is distorted by the movement of drone. For calibrating the image, we calculate a perspective projection transformation matrix between the distorted and the original images, and investigate the change of model parameters according to the angle of the projection. The model parameters with respect to the angle are stored in the lookup-table (LUT) which helps to easily find the transformation matrix for transforming the distorted projection image.
