After 123d catch will create the mesh, I import the mesh into meshmixer which provide me an opportunity to fix the mesh or make some adjustment.
By using meshmixer I be able to make the surface smoother and fill all the hole in the mesh. The completed model should be smooth and solid, it can be seen at figure 2, 3.
