Embodiment Construction
[0050] The preferred embodiments of this patent will be described in further detail below in conjunction with the accompanying drawings.
[0051] The invention discloses a method for automatically calculating the volume of ship-borne sand and gravel supporting real-time monitoring, see figure 1 , the principle of this method is to obtain the 3D model of the empty ship and the 3D model of the fully loaded ship, detect and extract the feature point pairs of the point cloud data, and then realize the automatic registration of the high-precision point cloud, and finally according to the elevation of the empty and full ship point cloud data The value is integrated by the difference to calculate the sand load of the ship.
[0052] Overall technical process of the present invention is as figure 2 As shown, firstly, the point cloud data of the empty sand carrier is obtained by using the 3D laser scanner equipment, and the standardized processing and modeling are put into the warehou...
