Occlusion identification research between virtual and real object in augment reality
增强现实环境下虚实物体遮挡判断方法研究

This paper investigated two methods for occlusion identification. One was triangle-based virtual objects reconstruction method, another method was the construction of real objects by virtual model. The former did not need to carry out pre-processing for the environment. The latter need to carry out pre- processing for the environment, but the advantages of it were easy to be realized, and had a good real-time performance. Firstly, described the realized methods of these two methods in detailed. Then, gave a detailed performance test in comparison with these two methods. Finally, drawn the conclusion about how to select the occlusion identification based on the performance test.
