A SURVEY ON MARKER-BASED TRACKING SYSTEMS IN AUGMENTED REALITY AND DESIGN OF MULTI-LAYER MARKER MODEL

Öz

Augmented reality is a technology which allows virtual contents generated by computer to be displayed on the real world in real time using computer vision techniques. Tracking methods play an important role in augmented reality applications. In this work, a survey on marker-based tracking systems in augmented reality is presented and a multi-layer marker model is proposed. Multi-layer marker model enables details of the virtual contents displayed on the real world to be seen closely and prevention of image loss occurring when moved away from the marker. Tracking distances are given for markers in each layer. Inner layer and outer layer give good results for short distances and long distances, respectively

ARTTIRILMIŞ GERÇEKLİKTE İŞARETÇİ TABANLI TAKİP SİSTEMLERİ ÜZERİNE BİR LİTERATÜR ÇALIŞMASI VE TASARLANAN ÇOK KATMANLI İŞARETÇİ MODELİ

Öz

Arttırılmış gerçeklik, bilgisayarlı görü teknikleri kullanılarak, bilgisayar ortamında oluşturulan sanal içeriklerin, gerçek görüntülenebilmesine olanak sağlayan bir teknolojidir. Takip yöntemleri arttırılmış gerçeklik uygulamalarında önemli bir rol oynamaktadır. Bu çalışma kapsamında, arttırılmış gerçeklikte işaretçi tabanlı takip sistemleri üzerine bir literatür çalışması yapılmakta ve tasarlanan çok katmanlı işaretçi modeli tanıtılmaktadır. Çok katmanlı işaretçi modeli, gerçek dünya üzerine düşürülen sanal içeriklerin detaylarının yakından görülmesini ve işaretçiden uzaklaşıldığında oluşan görüntü kaybının önüne geçilmesini sağlamaktadır. Her bir katmanda bulunan işaretçi için görüntülemenin yapılabildiği takip mesafelerine çalışmada yer verilmektedir. İç katman kısa mesafeler için, dış katman uzak mesafeler için başarılı sonuçlar vermektedir
