The Evaluation of Distance Accuracy and The Test Target Manufacturing of A Terrestrial Laser Scanner

Albeit the use of terrestrial 3D laser scanner (TLS) in the parts of landslide monitoring, cultural heritage documentation, civil engineering, urban engineering, etc. is increasing more and more, there is no international standardization regulation about the accuracy evaluation of the geometric element values, target, instrument calibration and test procedures, etc. Accordingly, this study deals with the manufacturing of TLS performance test target and the evaluation of TLS distance measurement and shows its suitability as the test target.
