What do a self-driving car and a care robot have in common? The answer: in order to orient themselves in their environment, both must be able to reliably recognize things and living beings around them. This "machine vision" is still a major challenge for engineers. One of the techniques works by calculating depth information from camera images using sophisticated algorithms. This allows conclusions to be drawn about the three-dimensional shape. Tobias Holl (16) from Germering near Munich developed such an algorithm in his research project. As a result, he was able to create 3D images from photos of a cordless screwdriver and an elephant that appear amazingly three-dimensional.
