An automatic completion method of underground pipeline three-dimensional point cloud data
PendingCN122265021AGuaranteed Repair AccuracySuppress random noise interferenceImage enhancementGeometric image transformationPoint cloudAlgorithm
The present application relates to the technical field of three-dimensional modeling, in particular to a kind of automatic completion method of underground pipeline three-dimensional point cloud data, comprising the following steps: according to underground pipeline three-dimensional point cloud data, the boundary ring vertex coordinates of the missing area inside point cloud are identified, the Euclidean distance sum between boundary ring vertex is calculated, the average curvature numerical value of boundary vertex is counted, the normal vector deviation variance value of the least square fitting plane where boundary is calculated, and the missing boundary geometric feature triplets are generated.The present application constructs local geometry frame sequence and projects adjacent points into the law plane to generate dynamic cross-section profile parameter set, breaks through the limitation that traditional method assumes pipeline as standard cylinder, can capture and restore local deformation or non-circular cross-section features that pipeline occurs along path, the generated mesh edge is stitched with original point cloud, and the integrity of underground pipeline model after reconstruction in geometric form and topological structure is ensured.

Bicycle rim with spoke hole base ring
The bicycle rim with the spoke hole base ring comprises a rim body, the spoke hole base ring, spoke nuts and spokes, an annular closed cavity is formed in the rim body, and the spoke hole base ring is arranged on the bottom wall, corresponding to the radial inner side of the closed cavity, of the rim body. The spoke hole base ring comprises a ring belt and a plurality of spoke hole bases arranged on the ring belt, spoke holes are formed in the spoke hole bases, the tooth cap ends of the spokes penetrate through the spoke holes to be coaxially assembled with the spoke nuts, the surfaces of the spoke hole bases are perpendicular to the axis direction of the spokes, and the spoke holes are formed in the spoke hole bases. The installation direction of the spoke nut is the same as the installation direction of the spoke, one side of the spoke can be prevented from deviating and making contact with the spoke nut to form a break angle so as to be broken, meanwhile, the other side of the spoke is prevented from being not in contact with the spoke nut to be loosened, the tension of the spoke is prevented from being reduced, and the spoke is more worry-saving and durable. And meanwhile, the riding safety of a user is improved, and the requirement for light weight of the rim is met.
