摘　　要：Marching Cubes(MC)算法是经典的面绘制算法,但它存在数据源复杂、分割方法单一和三维网格存储量大的问题。针对这种情况,提出了改进策略,主要是从图像预处理、图像分割及三角形网格简化方面加以讨论,并给出了相应的算法,由此使得重建算法的数据源信息更准确,适用面更广,存储效率更高。Marching cubes（MC） algorithm is a classical algorithm of surface rendering,but there is some problem such as the complexity of image source,the simplex of segmentation and the storage of mesh.The MC algorithm is modified and improved in several aspects.The main research contents of the algorithm include image pre-processing,image segmentation and mesh Simplification.Based on the improving algorithm,the image source of three-dimensional reconstruction can be more exactly,the storage can be more efficient and the applying can be broader.
