The present application belongs to the technical field of ships or other water vessels, and specifically relates to an intelligent positioning and assembling system based on ship segment construction. A solid-state laser radar and a linear array infrared camera are fixed in the butt joint area of the outer plate of the segment to be assembled to obtain local point cloud data, and the theoretical position of the rib plate and the theoretical trend of the weld are extracted from a digital template as prior topological constraint features. For the point cloud missing area caused by physical shielding of adjacent segments, a non-uniform rational B-spline surface fitting algorithm based on a moving least square method is used to reconstruct the virtual point cloud with the prior topological constraint features as the boundary conditions. The complete local point cloud containing the virtual point cloud is iteratively closest point registered with the target point cloud to calculate the pose deviation, and the deviation is input into a three-degree-of-freedom servo driving mechanism to perform pose adjustment. The present scheme overcomes the defect of missing butt joint feature information caused by structural shielding in a narrow space, and realizes the calculation of segment pose deviation and adjustment of the actuator in a restricted space.
