3D dynamic scene reconstruction simulation of ship movement path
To ensure the safety of ship movement,a three-dimensional dynamic scene reconstruction method for ship movement path is studied.During ship navigation,visual sensors such as cameras are used to continuously obtain images of the ship's movement path in unknown environments;Using an ORB based feature extraction algorithm to extract feature points within the ship's movement path image,and matching feature points based on Hamming distance;Obtain camera pose information by calculating feature point matching results through polar geometry;Adopting a keyframe selection mechanism based on feature correlation filtering to obtain all keyframes,the 3D dynamic scene reconstruction of ship movement path is achieved through point cloud concatenation of keyframes.The simulation results show that this method can not only effect-ively achieve feature point matching,but also achieve a correct matching rate of over 97%.The mean square error of the 3D scene reconstruction results is controlled below 0.2,and the structural similarity is always above 95%.
