摘要
Virtual endoscopy system are researched in this paper. We use boundary model and local feature structure to realize tissue segmentation. A new efficient algorithm is presented to solve path planning based on distance transform. As for real-time processing, a frame in virtual endoscopy is divided into near viewpoint part and far viewpoint part based on volume data characteristics in our method. In the aspect of scene rendering, a ray casting algorithm based on the boundary voxel is proposed. We can voyage in virtual endoscopy system in real time with high quality images to use these techniques.
