摘　　要：在水下对空成像过程中,物体受海水波面折射作用的影响,会产生严重的畸变。为了快速有效地校正图像,对随机波动的波面进行重建就成为一个重要的课题。利用基于光线透过小孔形成的光斑变化,分析并计算得到波面的梯度信息,进而通过梯度算子的最小二乘法反演波面高度,最终实现波面的三维重建。实验表明该方法能有效的复原波面,为扭曲图像的矫正提供了条件。In the process of underwater air-to-air imaging,objects are affected by the wave surface refraction of the seawater,which will cause severe distortion.In order to quickly and effectively correct the image,it is an important subject to reconstruct the wave surface of random fluctuation.Based on the previous work,this paper analyzes and calculates the wave gradient information based on the change of light spot formed by the light passing through the small holes,and then uses the least square method of the gradi⁃ent operator to invert the wave height to finally realize the 3D reconstruction of the wave.Experiments show that this method can ef⁃fectively restore the wave and provide conditions for the correction of distorted images.
