Laser scanning is a new technology that provides accurate and dense 3D measurements from the object. Development of laser scanners and techniques has led to several successful applications in the field of land surveying, forestry, industrial design and city planning. However, airborne laser scanners have not broken through in the field of agriculture and precision planning due to high expenses ...

This paper briefly describes the preliminary results of an experimentation aimed to test a new non-destructive methodology based on the integrated application of 3-D terrestrial laser scanning and acoustic techniques in the ultrasonic range (54 kHz) in evaluating the quality of stone materials. Our target is to evaluate the state of conservation of stone building materials by correlating ultras...

We present results from a terrestrial laser scanner (TLS) and mobile mapping system (MMS) based investigation on forest defoliation caused by the European pine sawfly (Neodiprion sertifer) in a Scots pine dominated forest. The TLS and MMS results are compared with simultaneous visual estimation of the defoliation intensity as percentage of needle loss in the living crown. The capability of TLS ...

introduction: three-dimensional (3d) scanners are widely used in medicine. one of the applications of 3d scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. the aim of this study was to evaluate the precision and accuracy of a modified 3d scanner fabricated in this study. methods: in this work, a 3d scan of the human body was o...

Terrestrial laser scanning method is widely used in three-dimensional (3-D) modeling projects. Nevertheless it usually requires measurement data from other sources for full measurement of the shapes. In this study a 3-D model of the historical Mevlana Museum (Mevlana Mausoleum) in Konya, Turkey was created using state-of-the art measurement techniques. The building was measured by terrestrial l...

The patches of the rice paddies are generally positioned by a traditional surveying method such as Plane Table and Total Station in Korea. This study has been undertaken to check whether TLS (Terrestrial Laser Scanner) could meet the accuracy standard, compare TLS survey data with those one of the new modern survey technologies such as digital aerial photogrammetry and RTK GPS. As a result, it ...
