摘要
文章结合实测数据对近景摄影的误差来源进行分析,在此基础上,研究了依据摄影照片所绘制的裂缝形态的误差,得出了误差限的表达公式,给出了误差控制办法,并结合混凝土结构试验和结构检测方面的实践对这种办法进行了评价。
Why error happens in short-distance photogrammetric survey is analyzed combining the actual measured data. Based on the analysis of the error caused hy photography, a formula for the limit of error is given and a method for error control is accordingly provided and appraised in the test and inspection of concrete structure.
