A Practical Guide to Marker Based and Hybrid Visual Registration for AR Industrial Applications

摘要

This paper presents two visual registration solutions for a mobile augmented reality system. The first one is a marker based solution whereas the second one is a hybrid approach. The hybrid method combines a coded marker technique for the initialization in the first frame, and a markerless registration in the next frames thanks to a 3-D model based tracking method. Because this mobile augmented reality system is designed for use in the industrial context of maintenance assistance for instance- robustness, accuracy, real-time and user comfort are the main concerns. For the different stages of the proposed solutions, various algorithms were evaluated to determine which one offers the best robustness and efficiency.
