Title:
AUTOMATIC INTRODUCTION DEVICE FOR CELESTIAL BODIES, TERMINAL DEVICE, AND ASTRONOMICAL TELESCOPE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2004/107013
Kind Code:
A1
Abstract:
An automatic introduction device automatically introduces a target celestial body by controlling an astronomical telescope to rotate around at least two shafts. The automatic introduction device includes: an imaging device capable of imaging a celestial body at a plurality of focal distances; a celestial body database; an image processing section for extracting information on each celestial body from the celestial body images imaged; and a celestial body identification section for identifying the imaged celestial body by comparing information on each celestial body extracted to the celestial information in the celestial body database. Alignment processing is performed by demarcating coordinate conversion information on the coordinate system of the astronomical telescope with respect to the celestial body coordinate system according to the position information on the celestial body identified. In automatic introduction, after a target celestial body is introduced, the celestial body is imaged and the celestial body of the celestial body image imaged is identified. According to the position information on the celestial body identified, the astronomical telescope is controlled to rotate so as to introduce the target celestial body at the center of the field of view. By stepwise shifting the focal distance of the imaging device toward the telescopic side, it is possible to improve the alignment accuracy and automatic introduction accuracy.
