Abstract
This invention proposes a ship attitude coupling method and system based on binocular vision and lidar, relating to the field of ship technology. Addressing the problems of existing ship monitoring technologies being significantly affected by environmental and weather conditions, unable to analyze the ship's specific position and movement trajectory, and unable to predict the ship's course in advance, this invention designs a method that uses a non-contact binocular vision sensor and lidar for joint monitoring, achieving three-dimensional ship monitoring. Specifically, it uses lidar to collect real-time ship point cloud data and extracts feature information from this data, then couples it with graphic information from the binocular vision sensor to construct a three-dimensional coordinate system, fusing planar space into precise monitoring data. This achieves the complementary advantages of data and images, enabling more accurate capture of ship motion and attitude data, and improving the system's monitoring performance and reliability in all weather conditions and complex scenarios.
