The need for high-quality HD maps
As we move towards an autonomous future, industry analysts agree that HD maps are essential to making safe autonomous driving possible. The TomTom HD Maps are next-generation maps that deliver highly accurate, up-to-date and realistic representations of the road. HD Maps improve localization to centimeter-level accuracy and sensor perception, which leads to safer path planning by automated driving systems.
Our HD Maps are made and maintained with a multi-sourcing approach, terabytes of high-quality data coming from survey vehicles, as well as accurate crowdsourced car sensor data and other professional sources. All of these are necessary to create a rich and high-quality HD Map that you can trust.
A multi-source approach to HD mapmaking also minimizes the time between a road change taking place in real life and the moment that change is reflected on the digital map. Referred to as reality to map time (R2M), the shorter R2M is, the more accurate the HD map and the safer it is for AD systems to rely on.
In this article, we will look at the proof of concept developed together with HELLA Aglaia and some promising first results.
