Titel:
Estimation of opto-mechanical parameters for calibration of laser scanners 
Abstract:
Within this paper an approach of calibration for a terrestrial laserscanner with two mirrors driven by two galvanometers is presented. This includes a mathematical model for the interior ofthe laser scanner as well as the determination for the parametersto be calibrated. The mathematical model is derived from the functionalityof the laser scanner, whereby the principle of “Ray Tracing‿ was used. According to the inner structure of the scanner device andthe functionality of the scanning system th...    »
