Poisson Surface Reconstructions Experiments

Procedure:

• Open the point cloud file in Meshlab.
• Clean the point cloud by removing any outliers and irrelevant data.It also reudces the number of points to be processed.
• Compute Vertex Normals. Go to Filters->Normals,Curvatures and Orientation->Compute Normals for point sets.We have used default meshlab parameters for computing the normals.
• Apply Poisson Reconstruction. Go to Filters->Remeshing,Simplification and Reconstruction->Surface Reconstruction:Poisson. To obtain good results, you may have to experiment with giving different octree depth value.Normal direction may need to be flipped for orienting them outwards.(Filters->Normals,Curvatures and Orientation->Flip Faces)
• To add color, Go to Filters->Sampling->Vertex Attribute Transfer.Select color transfer check box and source and destination files appropriately for mapping.
