Advanced map compilation technology NAVTEQ True

Navteq has presented its new collection system NAVTEQ Mapping True.
The company has begun implementing this new technology in its vehicle fleet data collection in the U.S., further enhancing the company's ability to deliver a growing range of digital maps high calidad.

NAVTEQ True represents a new era in data collection, as it uses unique technologies in the industry both in terms of quality and scope. Through a combination of LIDAR cameras, panoramic, high resolution, GPS and IMU positioning, all data are geo-referenced, enabling joint superimposition of images and 3D data in order to create a digital representation with a much greater level of detail.
The unique way in which this technology allows data capture results in a key platform for transforming the digital maps from a 2D representation to another in 3D. The True NAVTEQ specific components include:
• Rotating LIDAR Technology
The collection technology Navteq LIDAR uses a proprietary architecture that captures more than 1.5 million 3D data points every second, representing a significant improvement over other lidar systems. The rotary laser can act on a larger radio-reaching approximately 120 meters, and faster, enabling NAVTEQ collect signals from the highway while driving to the speed limit, at the same time you can even capture data from small mileage markers. While other scanners use linear LIDAR systems that capture at an angle of 90 degrees, 64 lasers rotating Navteq LIDAR images collected at 360 degrees. Among other features, this system also includes the ability to automatically generate attributes as a bridge height or width of a lane with a precision of centimeters, while expanding the field of vision behind objects to obtain more accurate dimensions when 3D representations of processing, compared to visualizations based on the type aerial imagery sources.
• Combined panoramic cameras, high resolution
True NAVTEQ is much difference in the use of multiple camera angles and panoramic cameras. This combination not only affects the collection process, but also the efficiency with which data can be processed and reach the end user, a very important aspect. The panoramic cameras can capture an immersive photography one location, thus supporting the creation of images of streets. For its part, the simultaneous use of multiple camera angles to capture additional details, such as the menu text printed on the sign at a restaurant in the same way.
• GPS and IMU Positioning
True NAVTEQ builds on these two important tools to help ensure a correct position of the vehicle at all times. Incorporating Inertia Measurement Unit (IMU, Inertial Measurement Units) is a key element when collecting hard to capture adequately attributes such as curves and slopes, for which it requires a greater level of accuracy in positioning.
True NAVTEQ is designed to house all these components in an approach all-in-one ', thereby facilitating a more sophisticated synchronization of various data inputs captured during the collection, as well as enabling NAVTEQ geographic analysts benefit from use and scale implementation easier.
