In this paper researchers propose a method for capturing 3D data from photos of the human eye! This is a massive breakthrough as up until this point capturing the human eye through photogrammetry has proven to be impossible. In the paper the researchers no only manage to capture the overall shape of the eye exterior but also manage to make a 3D reconstruction of the iris inside!
The reason why this is a major breakthrough is that photogrammetry is severely hampered by reflective and transparent surfaces – to get around this issue some practitioners have taken to using 3D sprays designed to remove the gloss and transparency of an object so it can be easily scanned ie. a glass vase. However for obvious reasons this is not possible with human eyes.
This breakthrough is very exciting for me as it can open up the possibility of no only scanning human eye but also transparent objects like sea waves or water ripples – something that I have wanted to incorporate in my work for some time now.
