海战中航拍图像模拟的生成算法仿真

Generation Algorithm Simulation of Aerial Images in Naval Warfare

海战中通过多幅航拍图像生成包含多信息的图像分析依据.对海洋中的图像进行稳定采集面临较大困难,航拍是个动态移动的过程,为了得到全面的数据,需要在同一区域反复拍摄,拍摄过程较为随机,形成大量的、角度重叠度的海量图像。在传统卫星和正射海战航拍图像生成的过程中,受到大重叠图像的影响,需要对图像进行特征的筛选和最优角度的区分,排查过程存在较大缺陷,图像效果较差。提出了一种依据聚类算法并行化的航拍图像模拟生成方法,分析海上作战中航拍图像数据并行化处理的具体过程,采用同样算法的并行化处理方法,将运行在CPU上的串行航拍图像模拟程序转换成并行程序,提高处理航拍图像效率,给出了海上作战航拍模拟图像处理流程,通过图像融合方法对多幅图像中的感兴趣区域进行提取,得到高质量的海上作战航拍模拟图像。实验结果说明,所提方法获取的海上作战中航拍图像较为清晰,具有较高的模拟精度。

Multi Aerial photograph is used to provide reliable analysis basis of the image which contains much information in naval warfare. It is difficult to have a stable image collection in the sea. In order to get the comprehensive data of the image, it is usually need the photograph to be shoot in the same area frequently. The process of shooting is random, and it will produce multi pictures with many angular overlap. Affected by the large overlapping images, the process of photographing of traditional satellite and aerial photographing of orthographic naval warfare have to make a characteristic screening of the images and a discrimination of the optimal angle. The process of the discrimination has a big defect and the value of the image is poor. This paper proposes a clustering algorithm based on parallel aerial image generated simulation method that can analysis the parallel processing of the aerial image data parallel pro- cessing in naval warfare and uses the parallel processing method based on the same algorithm. The method proposed in this paper transmit the simulation program of the serial aerial image running on the CPU into a parallel program, so that the efficiency of processing aerial image is improved and the maritime combat aerial analog image processing flow are given. By means of extracting the image from multiple images in the interested area, high quality aerial simulant images in naval warfare is got. Experimental results indicate that the proposed method for naval warfare in aerial image is relatively clear and has a high simulation precision.
