Outlines a method to reconstruct objects that are traditionally hard to image using structure from motion. The above image illustrates the observed error - where blue is closer to the ground-truth. The aim is to make sure metric information is maintained when a real object is reconstructed, allowing for precise and relevant measurements. In general this research intends to allow archeologists a ‘non-invasive’ means to study archeological sites, where they no longer need to appropriate artifacts from a site, but instead can image them with a camera and perform analysis off-site.
