Sign detection and gps localisation

Hi there. I'm looking to make a project for a road safety startup to localize signs. Basically, they want an accurate way of geopositioning signs in the road. Some ways to achieve this (at least I think so) involve constantly taking Gps data from a Gps module and either using stereo depth, structure from motion(creating a 3d scene), or some other technique. The end goal is to map out the signs so that they are accessible in a data base …
