摘　　要：在工业摄影测量中,影响测量精度的要素较多,为了提高摄影测量精度,在控制网型、被测物体、摄影距离等其它条件相同的情况下,采用不同的工业摄影测量相机,研究每个摄站不同旋转基线次数对精度的影响。通过对比不同旋转基线个数工况下的测量重复性,得出16个相机旋转基线比传统的2个相机旋转基线的测量重复性精度有明显提高;且随着相机旋转基线个数的增加,测量精度也会逐步提高。There are many factors that affect the accuracy of measurement in industrial photogrammetry.In order to improve the accuracy of photogrammetry,different industrial photogrammetry cameras are used to study the influence of different number of rotation baseline of each photogrammetry station on the accuracy under the same control network,measured object,photographing distance and other conditions.By comparing the measurement repeatability under the number of different rotating baselines,it is concluded that the measurement repeatability accuracy of 16 cameras rotating baselines is significantly higher than that of the traditional 2 cameras rotating baselines.With the increase of the number of camera rotating baselines,the measurement accuracy will gradually get improved.
