明暗恢复形状(shape from shading,SFS)算法是三维重建中不可缺少的关键技术。该方法通过单幅图像中物体的灰度的亮度信息,求出每个点的相对高度和表面法向量,现有的SFS线性化算法利用泰勒级数进行展开忽略了高阶部分的影响,导致三维重建的图像不够精确等问题。为解决三维重建精度问题,本文提出一种基于SFS算法改进的高精度快速水下图像三维重建方法,在提高三维重建精度的前提下,解决了对本轮数据利用率不够、迭代速度慢等问题。将其应用在真实图像和虚拟图像上进行实验评估以及三维重建的量化分析,验证了相比于经典 SFS 线性化算法和SFS最小化算法,本文提出的SFS算法改进的高精度快速水下图像三维重建方法,取得了令人满意的信噪比和图像信息熵值。

Shape from shading (SFS) represents an indispensable key technique in three-dimensional (3D) reconstruction. It leverages the luminance information of the gray scale of the object in a single image to determine the relative height and the surface normal vector of each point, and the existing linearization algorithms of SFS leverage a Taylor series approach for the expansion, thereby ignoring the influence of the higher-order part, which causes issues, such as the inaccuracy of the reconstructed image in 3D. Thus, to solve the accuracy problem of 3D reconstruction, a high-precision, fast 3D reconstruction method for underwater images is proposed based on the enhancement driven by the SFS algorithm. This method solves the existing issues regarding insufficient data utilization and low iteration speed, thereby improving the accuracy of 3D reconstruction. Regarding the application to real and virtual images for the experimental evaluation and quantitative analysis of 3D reconstruction, the proposed SFS algorithm-enhanced high-precision and fast 3D reconstruction method for underwater images delivers satisfactory signal-to-noise ratios and entropy values regarding image information compared with classical SFS-linearization and SFS-minimization algorithms.
