摘要
为了提高航空光电成像系统对地面目标的定位精度,提出了平台目标自主定位的方法,并给出了实现的方法和途径,即将GPS系统和航空姿态测量系统直接固联在航空光电成像平台上,与光电成像平台系统结合直接实现目标定位。分析了影响目标定位精度的因素,分析结果表明,目标自主定位的方法可以消除传统方法中减振器带来的误差。一般情况下,平台自主定位比飞机系统定位的精度至少高25%。
In order to enhance the ground object orientaton accuracy of a aerial photoelectric imaging system,a self-determination orientation method is proposed, in which the GPS system and aviotion 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-deternunation orientation method can eliminate the error of the traditional method brought by a absorber. Generally, the accuracy of self-determination orientation system is at least 25% higher than that of the aircraft system.
