Point cloud data classification.
Scanning device
Ordered point cloud
Arrange at a constant density in the direction of rows and columns
Disordered point cloud
Indefinite density exists anywhere in space
Scan quality
Miscellaneous
Miscellaneous points are points that are measured incorrectly and are invalid points; after zooming in, you can see that they are clearly separated from the surface of the part and exist in isolation
Noise point
Because of the reverse equipment and measurement method, there are systematic and random errors in the measurement data; some of the measurement points have relatively large errors that exceed our allowable range; this is the noise point
Generated during operation
Redundant point
It is because of the problems of flattening, measuring angle, etc., that overlap redundant points
