基于Context Capture软件倾斜摄影空中三角测量优化研究

Research on Optimization of Aerial Triangulation of Oblique Photography Based on Context Capture

针对目前Context Capture软件空中三角测量解算失败率高、耗时长、精度低的问题,笔者分析了倾斜摄影作业流程,得出空中三角测量解算结果主要与输入数据有关的结论。为了验证该结论,笔者从四个方面对空中三角测量解算进行优化,并通过不同类型的实际项目进行验证。结果表明:利用本文的方法对输入数据进行优化后,在一定程度上,提升了空中三角测量解算的成功率、效率和精度,对于实际生产项目来说,具有很强的实用性,希望可以为同行带来借鉴。

Aiming at the problems of high failure rate,long time-consuming and low accuracy of aerial triangulation solution in Context Capture software,the author analyzes the operation process of oblique photography,and draws the conclusion that the solution result of aerial triangulation is mainly related to the input data.In order to verify the conclusion,the author optimized the aerial triangulation solution from four aspects,and verified it through different types of practical projects.The results show that after the input data is optimized by the method in this paper,the success rate,efficiency and accuracy of aerial triangulation solution are improved to a certain extent,and it has strong practicability for actual production projects.Bring lessons to peers.
