摘要

Point cloud data of complex product with small changes of surface has narrow data range, high spatial relativity and smooth data change. It is not sensitive to feature extraction and shape recognition. Point cloud data enhancement based on layer connected region is proposed. The two-dimensional matrix is calculated to describe point cloud data reflecting the product shape and spacial relationship. Point cloud data is divided into two layers. Local point cloud data is enhanced in the connected region of each layer. The point cloud data enhancement is evaluated by contrast enhancement index and equivalent number of looks. Example shows that point cloud data enhancement based on layer connected region can convert non uniform distribution point cloud data to uniform distribution point cloud data, improving the contrast of the point cloud data.
