摘　　要：针对现有溢油可视化方法的优缺点,研究一种新的海面溢油可视化方法,提出采用纹理投影的方法实现海上溢油的可视化,并针对纹理投影方法导致的边缘锯齿现象进行高斯平滑滤波,实现了纹理边缘的平滑过渡,取得了良好的动态可视化效果。该方法已成功应用于"溢油应急三维演练系统"中,证明了该方法的有效性和可靠性。A new visualization method of oil spill at sea surface was researched after analyzing the advantages and disadvantages of the present methods in oil spill visualization.Texture projection was proposed to implement the dynamic visualization of oil spill at sea surface.Besides that,Gauss smooth filter was used to make the edge smoother in the transition of the texture edge caused by texture projection,and a good dynamic visualization was achieved.The proposed method has been applied in ＂3D Oil Spill Emergency Response System＂ successfully,which proves that the proposed method is effective and reliable.
