This contribution describes our work focused on using a laser scanner for a railway application. In the work the laser scanner SICK LD-HD MRS400102 is used and tested on suspended mining locomotive of Ferrit, s.r.o. company. The scanner is tested for detecting an object in front of the locomotive operating in mining conditions.

The present thesis focuses on the analysis of the process of geometric documentation of monuments using new technologies and more specifically on the creation of three-dimensional model for the Agia Sofia church in Drama using laser scanner. Agia Sofia church is of great importance to the town of Drama and also to Byzantine architecture.

One focus of present chapter is defined by the further development of the technical vision system (TVS). The TVS mainly contains two principal parts, the positioning laser (PL) and the scanning aperture (SA), which implement the optomechanical function of the dynamic triangulation. Previous versions of the TVS uses stepping motors to position the laser

Radiological Laser Film Scanner Sampling Artifact
SPIE Proceedings, 1988Artifacts seen on laser digitized radiographs are analyzed and mathematically explained based on the concept of image contrast. Our investigation considered the following determinants: (a) laser spot size, (b) signal processing components, (c) image characteristics, and (d) observer performance.

Laser scanners are essential for scientific research, manufacturing, defense, and medical practice. Unfortunately, often times the speed of conventional laser scanners (e.g., galvanometric mirrors and acousto-optic deflectors) falls short for many applications, resulting in motion blur and failure to capture fast transient information. Here, we present

The aim of this dissertation is the remote assembly of a coloured 3d point cloud, derived from the Laser Scanner s measurements. The methodology included data collection, by taking measurements (four point clouds) with the Laser Scanner. Point cloud alignment, colour matching and modeling followed the above procedure.
