1) data preprocessing
The pretreatment of cloud data include cloud data repairing, point cloud registering, point cloud noise eliminates, cloud data compresses,
Cloud data is smooth and cloud data piecemeal.
Cloud data is repaired：The characteristics of due to the limiting of measuring apparatus, object own form to be measured, the cloud data of collection
In often include the various regions that can not be measured, be cavity.These cavities not only influence the visual effect of threedimensional model, more can
Influence the sequence of operations of later stage grid model.
Point cloud registering：In Three Dimensional Ground laser scanning, covered between the limitation at stimulated light scanner field of view angle and object
Influence, often station scanning can only obtain the cloud data under Current Scan instrument coordinate system, therefore, it is necessary to from the different angles of visual field to field
Scape is scanned, and the point cloud obtained under multiple websites is spliced, and obtains the three-dimensional data points under a unified coordinate system
Collection.
Point cloud noise eliminates：Inevitably exist in the mass cloud data obtained in measuring instrument many redundant points and
Noise spot, these noises can not only increase cloud data amount, and can influence the efficiency and precision of modeling, it is necessary to be eliminated.

Cloud data is very big, therefore can cause to represent that the mathematical modeling of curved surface and the difficulty of processing fitting algorithm increase, and can not use relative
Simple mathematic(al) representation describes threedimensional model, it is possible to using the thought of " first split and splice again ", finally carries out overall
With the shape for recovering primary entities.
2) three-dimension curved surface is rebuild
Measuring the cloud data collected makes it recover the geometrical model of original surface, and its essence is how " point " being changed into
The process of " body ".Curve reestablishing is to add topology information for scattered points first, and generally use triangular mesh generation, which is established, to be dissipated
The disorderly topological relation between point；On this basis, then using certain mathematical form go to describe measured target surface.
