Abstract：In order to improve the accuracy and efficiency of repairing holes in point clouds of irregular surfaces in construction engineering surveying and mapping,this article conducted research on intelligent repair methods for holes in point clouds of irregular surfaces in construction engineering surveying and mapping.By utilizing centroid changes and density clustering techniques to extract the point set of the void boundary buffer zone,the Household transform is used to achieve point cloud coordinate transformation,and orthogonal direction slicing and polynomial curve fitting methods are used to interpolate the point cloud in the void area.Generate a uniform grid based on fitting points to complete spatial intelligent patching.The research results indicate that the repaired point cloud performs well in terms of overall deviation,local curvature matching,and surface smoothness.
