A range scanner with a virtual laser
Image and Vision Computing, 2003Abstract A scanner is developed that can capture range and color data from four sides of an object and combine the data into a model of the object. The scanner has four synchronous heads that scan an object from four sides in a coordinate system that is attached to the object.

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

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.

Equations for the diffraction-limited resolution of laser scanners are developed to encompass all known forms of angularly deflected systems. This includes the polygon (pyramidal or prismatic) with or without optical power in its elements (such as lenticular or holographic), whether overillumi-nated or underilluminated, forming output beams that are ...
