摘要
以近景摄影测量为基础,探讨了测量在简单的砌体结构变形观测试验中的应用。试验中用数码相机进行数据的获取,并结合工业施工的实际现场条件对时间基线视差法进行讨论;同时编制相应的软件进行算法的实现,包括像点坐标的屏幕量测、变形值的计算以及绘制相应的符合建筑行业人员要求的砌体结构变形图等多项功能。
This paper discusses the application of close-range photogrammetry based survey in simple masonry structure deformation experiment. We employ a digital camera to obtain the original data. We also investigate pseudo-parallax according to the practical working conditions, whose software implementation includes the measurement of pixel coordinates, the computation of deformation value, drawing of masonry structure deformation graphs that satisfies the requirements of construction workers, etc.
