摘要/Abstract

摘要： 针对海战虚拟环境中对舰艇尾浪模拟的需要,提出了一种基于单视点视频对舰艇尾浪进行三维重建的方法。对视频图像进行高斯滤波等预处理,并从视频图像中提取尾浪区域,基于Shape From Shading(SFS)方法计算舰艇尾浪的高度场,生成尾浪网格模型,基于Compute Unified Device Architecture(CUDA)技术计算网格顶点的法线,重建出舰艇尾浪的三维模型。实验结果表明: 重建的尾浪具有较高的真实感,提高了尾浪的重建速度,在细节与实时性之间取得了较好的平衡,能够满足实际应用需要。

Abstract: To simulate the ship track in the marine virtual battle environment, a novel algorithm based on the single viewpoint video was proposed to reconstruct the ship stern wave. Gaussian filter was used to preprocess the video image and extract the long tail region from the video image; SFS algorithm was employed to compute the height field of the ship stern wave and generate its grid mesh; The normal of each vertex was computed based on the CUDA technology. The experimental results show that the reconstructed stern wave yields a good sense of reality. At the same time, it improves the stern wave reconstruction speed while achieving a balance between the realistic and real-time rendering performance to meet actual needs.
