Workflow for pinna model repair. There are three main procedures: hole filling, surface smoothing, and solidification. Among them, when the scanning system merges the point cloud, sharp protrusions may occasionally be generated due to misjudgment. In such cases, these protrusions must be manually filtered and treated as holes for filling.
