Terrestrial laser scanner is a kind of fast, high‐precision data acquisition device, which had been more and more applied to the research areas of forest inventory. In this study, a kind of automated low‐cost terrestrial laser scanner was designed and implemented based on a two‐dimensional laser radar sensor SICK LMS‐511 and a stepper motor. The new scanner was named as BEE, which can scan the ...

INTRODUCTION Our aims in this study were to (1) develop a method of measuring 3-dimensional (3D) tooth movement using a 3D surface laser scanner, (2) test the accuracy of this method, and (3) compare the measurements with those from cephalometric radiographs. METHODS A method of superimposing pretreatment and posttreatment models on the palatal rugae was developed, and an experimental model w...

Airborne laserscanning allows a very detailed sampling of the landscape within a more or less automated recording procedure. For the representation of models computed on the basis of this data mostly raster or triangulated irregular networks (TINs) are used, which do only implicitly store breakline information. For high quality surface modelling breaklines must be explicitly stored within the d...

Three-dimensional (3D) modeling has always been an important part of paleontological research and interpretation though digital reproductions of fossils are a recent phenomena. A highly accurate, interactive, 100 μm resolution, 3D, digital model of a fossilized basisphenoid-basioccipital from a juvenile Tylosaurus sp. mosasaur was generated using a 3D laser scanner and manipulated using VRML an...
