摘要

基于标记的增强现实的一般概念是使用标记作为对象跟踪在现实世界中添加虚拟对象。在其发展过程中,AR设备可以检测三维真实物体进行物体跟踪(3D object tracking),从而实现虚拟物体与真实物体的交互。然而,AR应用于一般设备,如Android智能手机,没有深度传感器,虚拟物体被添加,没有来自现实世界的深度信息,虚拟内容总是显示在真实物体的前面或上面,造成遮挡问题。遮挡是指距离用户较近的真实物体被较远的虚拟物体覆盖的问题。本研究提出了基于模型的遮挡(model - based Occlusion)方法处理遮挡问题,该方法必须事先知道来自真实物体的模型几何信息并将其注册到系统中。为了保持模型的几何信息与其真实对象的适用性,需要进行跟踪。在这种情况下,使用3D对象跟踪,利用已经在基于模型的遮挡中注册的真实对象。研究结果表明,在增强现实应用中出现的虚拟物体能够占据正确的位置。在这种情况下,使用3D对象跟踪,利用已经在基于模型的遮挡中注册的真实对象。研究结果表明,在增强现实应用中出现的虚拟物体能够占据正确的位置。在这种情况下,使用3D对象跟踪,利用已经在基于模型的遮挡中注册的真实对象。研究结果表明,在增强现实应用中出现的虚拟物体能够占据正确的位置。

Interactive Augmented Reality For The Depth Of An Object Using The Model-Based Occlusion Method
The general concept in marker-based Augmented Reality is to add virtual objects in the real world using markers as object tracking. In its development AR devices can detect 3D real objects as object tracking (3D Object Tracking) so as to allow interaction between virtual objects and real objects. However, the application of AR for general devices such as Android smartphones that do not have depth sensors, virtual objects are added without having depth information from the real world so that virtual content is always displayed in front of or on top of real objects and causes Occlusion problems. Occlusion refers to the problem when real objects that are closer to the user are covered by more distant virtual objects. This research formulates the handling of the Occlusion problem using the Model-Based Occlusion method in which the geometry information of the model from real objects must be known and registered in advance to the system. To maintain the suitability of the model’s geometry information with its real object, Tracking is needed. In this case using 3D Object Tracking by utilizing real objects that have been registered in the ModelBased Occlusion. The results of this study are the virtual objects that appear can occupy the correct position in the Augmented Reality application. In this case using 3D Object Tracking by utilizing real objects that have been registered in the ModelBased Occlusion. The results of this study are the virtual objects that appear can occupy the correct position in the Augmented Reality application. In this case using 3D Object Tracking by utilizing real objects that have been registered in the ModelBased Occlusion. The results of this study are the virtual objects that appear can occupy the correct position in the Augmented Reality application.
