数字地籍测量中大小棱镜测量误差的对比研究

Comparative Study on Measurement Errors for Prisms of Different Sizes in Digital Cadastral Survey

针对目前数字化地籍测量中常用的碎部测绘方法,通过实验对比得出了大棱镜和小棱镜分别在左右放置和前后放置、棱镜与测站距离变化等不同情况下的误差大小,给出了棱镜误差改正模型,提出了提高界址点精度的相应措施。

Aim at the commonly used method of detail survey in digital cadastral survey, through the experimentalcomparison, the size of error is obtained under the different conditions, such as the prisms of different sizes placed on theleft or right of boundary point and placed in front or behind of boundary point, and the distance changes from prism to observationstation, the prism error correction model is given, and the corresponding measures are proposed to improve theaccuracy of boundary points.
