The invention relates to the technical field of ocean, and discloses a method and system for reconstructing a three-dimensional structure of an ocean floating platform, and the method comprises the steps: collecting the volume point cloud data above a waterline of a plurality of scanning planes from the surface of a floating platform above the waterline through a laser radar, collecting volume point cloud data below the waterline from the surface of the floating platform below the waterline by using a sonar sensor; associating the moving position of the laser radar with the volume point cloud data above the waterline of the plurality of scanning planes, integrating the volume point cloud data above the waterline of the plurality of scanning planes to one plane, and extracting features to obtain a measurement model above the waterline; extracting features of the volume point cloud data below the waterline to obtain a measurement model below the waterline, and combining the measurement models above and below the waterline to obtain an overall surface model of the floating platform; the system comprises modules for implementing the steps. According to the method, overall reconstruction of the three-dimensional structure of a large floating platform such as a naval vessel can be realized, and the reconstruction precision is high.
