摘要:

针对全站仪单距偏心测量存在精度低、测距受限及精度变化无规律等问题,依据单距偏心测量的测量原理,对其精度进行分析,找出误差源。对于与测站不通视的待测点的坐标测量,提出了一种新的测量方法,实地测量验证结果表明,相对于单距偏心测量,该测量方法能显著提高测量精度并扩大测距范围。

关键词: 全站仪, 单距偏心测量, 精度分析, 改进措施

Abstract:

In view of low precision,short distance,precision change disorder appeared in the process of measuring operation,based on the basic principle of total station hidden point measuring in single distance,we analyze its accuracy and find its erroneous source.Regarding with coordinate survey of testing spot in barrier as with survey station, we propose one kind of new surveying method,and verify it in field measurement,compared to total station hidden point measuring in single distance.The results show that this measurement method can obviously increase measuring accuracy and expand distance range.

Key words: Total station, Hidden point measuring in single distance, Accuracy analysis, Improvement
