Point cloud normal estimation and Correspondence based on Normal shooting

Souce cloud: shape model
Target cloud: point cloud from Kinect
Normal cloud: a cloud of normal for shape model cloud

Step 1: Normal estimation based on point cloud itself
Step 2: Figure out the normal direction based on the view port position
Step 3: Find the correspondence in target cloud for each point in source cloud (shape model)

Results:
Figure 1 Red points: shape model cloud; Blue line: normal starts from point; colorful point: cloud from Kinect

Figure 2 Side view of Figure 1.

Figure 3 Top view of Figure 1.
Figure 4 Green points are the correspondences obtained from normal shooting
