Abstract

A simple but robust and efficient 3D laser scanner was developed for data point acquisition from an object surface. The system is mainly developed for digital registration of anatomical parts to be used in biomedical applications. A novel surface reconstruction algorithm is adopted to obtain an explicit 3D model for the measured object with adequate ease and accuracy. Some of the practical applications of this contact-less scanning system, as well as its first step metrological validation are presented.
