海底三维建模关键技术

分析了当前海底三维建模流程中的关键技术,为建模人员提供指导。海底三维建模方法分为基于图像内容建模和基于点状地形数据建模。前者模型精确,视觉效果较好,但建模速度较慢,适合于小范围建模;后者建模速度较快,且满足海底大范围三维建模的精度要求。在海底三维建模中,对于小物件,采用基于图像的建模方法,而大范围的海底地形,采用基于点状数据的建模方法。

Key Technologies of Seabed Three-Dimensional Modeling

We analyze the seabed key technologies of three-di- mensional modeling, which provide guidance for modelers. The three-dimensional modeling method divided into image content modeling-based and data modeling based on point-like terrain. The former model is accurate, and the visual effect is better, but its velocity of modeling is show, which is suitable for small-scale modeling. The latter modeling is faster, it can meet the accuracy requirements of wide range three-dimensional modeling of the seabed. In seabed three-dimensional modeling, small objects should be used in the modeling method based on image, but the seabed topography should be used in the modeling method based on data point.
