Calibration of a Simple, Low Cost, 3d Laser Light-Sectioning Scanner System for Biomedical Purposes

Abstract

Three dimensional scanning is gaining popularity in the biomedical field for various applications where a 3D model of the external features of an anatomical part is beneficial. An analysis of two different calibration techniques, an analytical method and a least squares method, for a simple, low cost, 3D laser light-sectioning scanner system is presented. Both methods are evaluated according to their ability to cope with noise in the input calibration data. The least squares approach shows better performance under noisy data conditions; however both appear suitable for the given application. Directions for future work are also discussed.
