机助法近景摄影测量网形设计系统SNOD-C

本文将机助法优化设计用于近景摄影测量,论述了机助法优化设计系统的结构、功能和设计方法,并研制了机助法网形优化设计程序系统SNOD-C。该系统可以对摄站点的数量,位置,每站摄影的象片数、摄影方式、控制点及物点的分布,摄影机,量测系统的选择和非摄影测量观测值的选择等内容进行设计。同时,以近代摄影测量平差理论为基础的SNOD-C的平差子系统SCBAR(即带相对控制的近景光束法区域网平差系统)也适用于一般近景摄影测量的数据处理。最后,本文给出了一个近景摄影测量网形设计的实例。

A System of Computer Aided Network Optimization Design in Close Range Photogrammetry SNOD--C

This paper applys computer aided optimization design to CRP.It has dealt with the structure,the function and the making method of a system of computer aided optimization design.Author has constructed a programming system of computer aided Network Optimization Design in close range photogrammetry SNOD-C.The system can design the contents of the number and the locations of photograph stations,the number of photos on each station,the photograph forms,the distribution of control points and object points,the selection of cameras and measuring instruments,the selection of non-photogrammetric observations,etc.At the same time,the SNOD-C's sub-system of self-Calibration Bundle Adjustment with Relative controls SCBAR,which is based on the latest theory of photogrammetric adjustment,is adequate to the data-handling of general CRP.At last a practical example of network design in CRP has been given.
