摘　　要：水下三维重建为提高水下潜航器的探测能力等领域具有十分重要的科研意义。本文基于朗伯体反射模型和水介质对光散射原理,将需要多幅图像进行的三维重建简化为水下单幅图像的三维重建。由于单幅图像进行三维重建在理论上是欠定问题,本文建立了条件外部约束,依据深度信息和表面法向的关系完成物体的三维重建。最后与明暗恢复法进行重建的结果对比,证明了本文方法的可行性。The underwater 3D reconstruction is of great significance for improving the detection capabilities of underwater vehicles.Based on the Lambert model and the principle of light scattering in aqueous media,a novel 3D reconstruction algorithm is proposed for only single image analysis instead of multiple ones in tradition.Since the single image 3D reconstruction is theoretically indefinite,a conditional constraint is applied accordingly.Following the relationship between the depth information and the normal direction of surface,the 3D reconstruction of underwater vehicles is accomplished.The reconstruction results from current approach is in line with the shading recovery method thus the algorithm is valid.
