为解决常规近景摄影测量方法用于平面地表变形监测时,由于影像倾角过大,造成匹配困难的问题。以非量测性的数码相机高精度几何标定技术和多基线极限倾角的数字近景摄影测量技术为基础,设计出用于监测平面地表变形的可靠方法。研究结果表明:平差精度可以达到毫米级,满足沉降监测的精度要求,验证了近景摄影测量用于平面地表变形监测的精度和可行性,为变形监测由常规孤立点测量拓展为面测量提供了便捷、可靠的途径。

To resolve the problem of matching difficultly which is arose by the obliquity of image technology of the non-surveying digital camera geometric calibration and multi-baseline utmost obliquity digital close-range photogrammetry, this study designed a credibility method used to survey plane terrain. Researching result shows that precision of adjustment can get to mm witch meets the accuracy requirements of settlement monitoring, and the accuracy and feasibility of close-range photogrammetry for monitoring the deformation of plane surface is verified. It provides convenient, reliable way to expand the deformation monitoring of the conventional outlier measurement to surface measurement.
