Target self-determination orientation based on aerial photoelectric imaging platform

In order to enhance the ground object orientation accuracy of an aerial photoelectric imaging system, a self-determination orientation method is proposed, in which the global positioning system (GPS) and aviation posture measurement system are directly fixed on aerial photoelectric imaging platform to realize the target orientation combing with the platform. The analysis of the effect factors on the orientation accuracy shows that self-determination orientation method can eliminate the error of the traditional method brought by an absorber. Generally, the accuracy of self-determination orientation system is at least 25% higher than that of the aircraft system.
