提出了一种基于OpenGL可编程管线的海底浅层声学探测数据三维综合可视化方法。通过处理，将侧扫声呐影像、多波束数据和浅地层剖面在同一视图下显示，可以方便的对海底地质环境多种信息进行综合判读并进行多维数据的交互式提取。利用纹理缓冲区处理侧扫声呐影像数据，具有数据加载量大的优点，避免了实际应用中纹理数据反复切换带来的延迟；并且探讨了侧扫声呐影像和多波束数据分辨率不一致引起的纹理贴图问题。该方法在南海海底峡谷区域的海底地质环境综合显示和分析中进行了应用，结果表明，该方法能处理多种格式的侧扫声呐影像，不受侧扫声呐影像和多波束测深数据分辨率不一致的限制，数据加载量大、绘制速度快。

A method based on OpenGL programmable pipeline was proposed to visualize sub-bottom acoustic data, which made it convenient to interpret and extract information from synthesize map. Texture buffer was used to access side-scan image because its high capacity was able to reduce texture transmission from CPU to GPU. The problem caused by the inconsistent resolution between multi-beam and side-scan image also was discussed. The result, used in canyon area of South China Sea, demonstrated that the 3D visualization model was able to deal with variety of formats, while loading much more data and performing efficiently.
