Paper Abstract

In the field of static surveying, the automatic Total Station Instrument is well known for its high precision of sub-millimeter in range measure and sub arc-second in angular measure. It is also named "surveying robot" for that it achieves the performance to be automatic and intelligent, such as the function of Automatic Target Recognition (ATR). By now, the research of its application has been focused on the field of static surveying. However, in the field of kinetic surveying its application also has a wide prospect because of its ATR function. In this paper, the results about our latest systematic research and development of its kinetic surveying capability was presented for the first time, which includes the following. 1) Testing and analysis of surveying lag and determination for the measuring moment. Achieving the function to time a certain surveying event with an accuracy of milliseconds by developing a program and uploading it to the GSI operation system which is embedded in the total station instrument. In order to test and analyse the surveying lag, the reflector fixed on the platform of the mechanism (Stewart Platform) can move at the designed trace that is controlled by the mechanism with enough precision. The trace can be measured and recorded by the mechanism and the automatic Total Station Instrument in the same time. By the correlation analysis of the results measured by the Total Station Instrument and the mechanism, the lag is about to 150 ms (the delay for the transmission was considered) and the uncertainty is about 2 mm. 2) The discussion about the sampling rate and surveying lag for a kinetic measurement was proposed at first, and the quantitative results were presented. 3) The development of the automatic kinetic surveying system based on the automatic Total Station Instrument which was used in kinetic surveying on a feed-supporting system of a 50 meter-model of the FAST project, in this application, the position uncertainty is less than 2 mm and the sampling rate is higher than 5 Hz. It shows that using of the automatic Total Station Instrument for contactless kinetic surveying on large scale has an advantage especially in the aspect of tracking velocity, range for measurement, sampling rate and position precision.
