In this paper, two coaxial light sources are added to four light sources based on Photometric Stereo (PMS), and we put forward a kind of gradient fast algorithm. The simulation and underwater experiments show that the proposed algorithm can eliminate the inuence of the shadow in four light photometric stereo algorithm and also reduce Mean Square absolute Error (MSE) and Relative Mean Square Error (RMSE) of underwater target 3D reconstruction, and can get underwater target albedo. This algorithm can be widely used in underwater target fast 3D reconstruction.
