Abstract：
 The double-view field star sensing detector and its star chart distinguishing method belongs to the field of posture sensor technology. The double-view field star sensing detector has one semi-transparent mirror in angle of 45 deg to the main optical axle installed before the lens system of common star sensing detector, and two lens hoods in the two incident light directions of the semi-transparent mirror to avoid spatial stray light interference. The light rays of the two view fields are transmitted and reflected separately in the semi-transparent mirror, passed through the same lens system and imaged in the same photosensitive detector. Compared with common single view field star sensing detector, the double-view field star sensing detector has higher precision, high chip utilization, small volume, low power consumption, easy installation and use, and other features. In addition, the corresponding star chart distinguishing method is also disclosed.
