The proposed vacuum package method for surface reconstruction for a whole plant model (a, b, c, d) built from four views and a partial model (e, f, g) built from a top view: partition of a 3D point cloud to sectors (a, e), reconstructing the 2D surface curve (b), final tight hull of a sector (c, f) and the final point mesh of the reconstructed surface (d, g)
