| 摘 要： | 探索了虚实融合的两种方法，即基于三角面片的虚拟物体重构法和基于虚拟模型的虚实融合方法。前者具有不需要对场景进行预处理等优点；后者虽然要进行预处理，且需预知真实场景的详细信息，但它实现简单，实时性好。详细研究与比较了这两种方法的具体实现方法及运行效率，通过在实验平台下的测试得到两种方法的详细性能指标，为增强现实挑选何种虚实融合方法奠定了基础。

| Abstract: | 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. |
