I want to calculate the surface area and the volume of an irregular bottle. Since the bottle is of an irregular shape, the volume and surface area cannot be calculated by simple solids of revolution integration technique. While reading a research paper, I found that I can take multiple images of the silhouette of my object from different angles, trace the silhouette, and then produce a wire-frame model of my object. Combining several crosssections, I can produce a wire-frame 3d model.
Can anyone suggest me where and how can I plot the silhouette of an object from an image? Like some graphing software or something. And how can I integrate multiple sets of plots of silhouettes to reconstruct a 3D model?
Images to trace the silhouette from would be like this.
And the final wire-frame model that I intend to create should look like this.
These two images are borrowed from this research paper. You can also get to know in detail about the method that I am referring to.

Also, feel free to suggest if you have better methods for doing the same thing.
P.S. - the software that is used in the research paper is a paid one. Also, the paper was published in 2006, and so I am sure that there are better methods available.
