| 摘 要： | 针对一种利用光测图像获取飞行目标空中姿态的方法,建立数学模型,并基于该模型,深入研究了目标姿态角的测量误差问题.结论：像面直线的截距提取误差对交会结果影响很小,倾角提取误差影响较大；两交会平面之间夹角过小将大大降低交会结果的可靠程度,实际测量时必须保证交会角足够大.考虑了该方法使用中的一些细节,为该方法的具体实现提供了依据.

| Abstract: | The Mathematical model of a method for measuring flying object′s 3D pose using optical images is constructed.Basing on the model,the error producing elements in the procedure of getting flying object′s pose angles are analyzed and their effects on measuring results of flying poses deeply researched.Conclusions:The slope error of the object′s center axis line on image planes has a much bigger effect on measuring results than the intercept error.The angle between two intersecting planes in the method has great influence on measuring accuracy and should be guaranteed big enough in real measurement.Some details in practical application of the method are discussed. |
