U.S: Nokia is working on its second generation of mobile mapping technology. It has developed a 68-megapixel mobile mapping system equipped with LiDAR. The new system offers higher-resolution panoramic imagery and more accurate 3D buildings and sign recognition.
Currently, Nokia is using its first-generation mobile mapping system in North America and Europe. This system is an array of four cameras mounted on the top of cars. The second-generation version has four cameras of 16.8 megapixels each. These cameras are equipped with fish-eye lenses to capture a full 360 degrees view surrounding the car. The system is also equipped with a highly-accurate LiDAR laser scanner to build up a digital picture of the surrounding environment. It is capable of covering around 200m in a roughly 40-degree arc around the front of the car. The system can capture around 700,000 3D data points at a time. These include the facades of buildings, street signs, road markings etc. These datapoints can be used to populate Nokia’s maps with 3D vector graphics of the topography of the landscape.
