Abstract

It is an object to provide a video projecting system that makes the picture center of a camera, which is controllable for arbitrarily setting of its height and azimuth angle, in alignment with a cursor projected from a video projector, measures a positional relationship between the video projector and a fixed star, carries out an interpolation operation or the like with reference to these values to calculate a position of the projector and its posture angle, precisely operates together with a fixed star projector, and projects a precise video. The posture of the camera is controlled so that the predetermined height and azimuth orientation on a dome are aligned with the picture center of the camera. The video projecting system makes a cursor projected from the video projector in alignment with the picture center of the video camera and measures a height and an azimuth angle of this point image and projector coordinates of the cursor at a plurality of points. A coordinate transformation is carried out on desired horizontal coordinates and a projected picture in accordance with measured data, set positions and posture angles of the projector and the like are calculated, a coordinate transformation is carried out on the basis of these values to display desired images and figures on desired horizontal coordinates.
