STUDY ON THE MESUREMENT FINISHED SHAPES BY TLS IN PAVEMENT WORK

Abstract

 The Ministry of Land, Infrastructure, Transport and Tourism published a manual of finished shape by TLS in 2016. Use of TLS is expected to increase in paving work. In the study measurements were made using TLS with the three different method. As a result, the time became longer with more measurements. In data processing, if there are many orientation points, the time required for coordinate conversion will increase. On the other hand, the noise processing time was shortened when the measurement range was narrow. Measurement accuracy increases as the distance between ground control points decreases. The error may be large near TLS installation.
