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
