多摄站系统质量分析及其法方程病态现象的克服

QUALITY ANALYSIS OF THE MULTISTATIONPHOTOGRAMMETRIC SYSTEM AND IMPROVMENTIN ITS ILL-CONDITIONED NORMAL EQUATIONS

本文介绍了一个多摄站（全方位）摄影测量系统。它适宜于近景摄影测量灵活的构网形式，包括全方位摄影。文中分析了多摄站摄影测量网平差的精度和可靠性，并介绍一种该系统试用的克服法方程病态现象的新方法。

:A new multistation photogrammetric system is recormmended in this paper.It suits the close-range photogrammetric nets, formed by the photograph whichmight be of multicover, or even taken in all directions. An analysis of theprecision and reliability of this system is given. Meanwhile, a new algorithmis suggested to be used for improving ill-conditioned normal equations.
