» Algorithms for the recognition of footprints

posted on: September-14 2011 by: dach

Tobias implemented some experimental algorithms to extract the footprints of out models.
The long term ambition is to fill the bottom side of our models because there is no possibility for scanning the contact surface.
So the area 2mm over the bottom of the point cloud is taken and by using a alpha-shape algorithm the edges of the model are extracted and clustered. After that a convex hull is generated from the clusters and from this hull a concave hull is derived. This approach should provide an encircling line. Having this line it should be possible to fill the area with ponits.
