The invention discloses a geometric detail feature removal method for point clouds. The geometric detail feature removal method based on rolling-method vector filtering and multi-normal technology includes 1), filtering a point-cloud normal vector field according to a rolling filtering method; 2), updating a point position according to the filtered normal vector field to complete detail feature removal. The geometric detail feature removal method has the advantages that the normal vector field is filtered according to the rolling filtering method, so that large scale features of objects are not obscured during removal of the detail features; by a multi-normal method, sharp features of the objects are prevented from being distorted, and accordingly, the geometric features of the point cloudmodels are edited; the geometric detail feature removal method can be applied to noise data and has high robustness and good promotion prospect.
