摘要
多基线、大重叠度影像增强了同名点匹配的可靠性,提高点位解算的精度,在近些年工程测量中得到很大的应用,主要集中在地形测图、建筑立面测绘、三维重建等工程领域。然而,在变形体的监测中,传统单基线大多基于直接线性变换算法进行点位的解算和精度的评定,难以达到变形观测所要求的精度。本文将探讨利用多基线近景摄影测量分析,验证在边坡位移监测中应用的可行性,实验证明该方法在边坡位移监测是可行的。
A large degree overlap of multi-baseline image, on the one hand, enhance the reliability of the same name point matching, and the orthe hand, improve the accuracy of solvering, which obtained great application in survey engineering in recent years. This mainly concentrated in topographic mapping, building facades mapping and 3D reconstruction. However, the traditional single baseline mostly use the direct linear transformation algorithm, which is difficult to achieve the required accuracy. This article explored the use of multi-baseline close range photogrammetry analysis, validation in slope displacement monitoring, which has been proved feasibility.
