摘要
本文针对方向网优化设计中定向角的特殊处理,简述了四种方法,并从平差和优化设计两者的要求出发,提出了投影矩阵法,详细论证了相应的公式及计算可行性。
This paper, in view of the special handle of orientation angle in direction nets optimization, describes four methods. The projection matrix method and the corresponding formula as well as the calculation feasibility are discussed both from adjustment and design optimization.
