Abstract

Video-based Augmented Reality (VAR) aims to add 3D virtual objects (3D VOs) to a real world video sequence, in order to provide additional and useful information to facilitate some tasks, like computer aided surgery, simulation in a real environment, satellite positioning, interior design, among others. To achieve a consistent and convincing augmented scene, it is necessary that the VOs are properly occluded by real objects (Occlusion Problem in VAR); in this paper, we present a strategy based on the use of the Kinect sensor to solve this problem. In the occlusion stage we evaluate distances between real and VOs. Then, the parts of the VO occluded by a real object are calculated and removed. We found that the Kinect sensor is appropriate to be used for handling occlusions in indoor environments, dynamic scenarios and real-time applications. Experiments showed comparable results with the state of the art in both issues: occlusion handling and processing time.
