Introduction

Based on the dynamic referencing technology, FreeScan Trak ProW is capable of capturing the spatial position of the scanner tip in real time to acquire an accurate and complete 3D data of large or middle-sized objects. The scanner does not require marker placement, thereby simplifying the procedures and reducing the influences on the scanned object to a minimum. The innovative scanning method offers a portable, efficient and reliable solution to scanning large and complex objects. It is mainly applied in aerospace or manufacturing industries, and other scenarios unsuitable for markers attachment.
