3D reconstruction method for ship models based on computer vision
To ensure the integrity and level of detail of ship model 3D reconstruction,a computer vision based ship model 3D reconstruction method is proposed.This method is based on binocular stereo vision to calculate the coordinates of the global ship target point cloud and generate three-dimensional point cloud data of the ship as a whole;After registering the data using a multi view point cloud registration method,it is input into a dense point cloud reconstruction network model us-ing multi-scale feature recursive convolution.Through this model,a deep 3D depth map of the ship model is generated.Based on this,the motion structure method is used to reconstruct the 3D curve in the ship depth map,render the color of the ship model,and output the 3D reconstruction result of the ship model.The test results show that this method can achieve reli-able matching of corresponding points between different images and determine the coordinate positions of each point;The spatial deviation of the model after 3D reconstruction is all below 0.015;The reconstruction of the ship structure can be com-pleted well,and the integrity of the reconstructed ship model is good,presenting the structural details of the ship clearly.
