NDS.Live Localization Module offers numerous possibilities

13. March 2024

Localization technologies such as GPS (Global Positioning System), GNSS (Global Navigation Satellite System), Wi-Fi positioning, mobile positioning, and inertial navigation systems (INS) allow us to precisely determine a user’s current position. Through the continuous development and integration of new technologies, navigation tools are becoming ever more powerful and offer improved navigation experience. The members of the Navigation Data Standard Association have set themselves the task of continuously developing innovative solutions and approaches. NDS.Live plays a central role in this development. Let’s find out what the NDS.Live Localization Module has to offer.

The NDS.Live Localization Module provides different types of localization objects to support localization use cases. 

Importance of localization

Localization is crucial in navigation development for several reasons:

The Localization module in NDS.Live provides different types of localization objects to support localization use cases. Localization objects represent real-world objects, such as signs or road-side furniture like posts and poles. If the sensors of a vehicle detect such objects along the road, then the application can use these to determine the vehicle’s position.

The Localization module offers the following types of localization objects:

The following figure shows an example of the visualization of an occupancy grid with lanes as overlay. Light pixels represent a high probability that a cell in the grid is occupied. Dark pixels represent a high probability that a cell is unoccupied.

In addition to the localization objects themselves, the Localization module provides attributes that allow to model relations between the localization objects and roads, lanes, or road surfaces.

Localization objects are provided using the corresponding geometry layer. The relations between localization objects and map features are provided using the corresponding attribute layer.

The Localization module includes the following files:

Provides attributes of the localization layers.attributes.zs
Provides instantiations of templates used in the Localization module.instantiations.zs
Provides the localization layers for landmarks, obstacles, and occupancy grids.layer.zs
Provides metadata for the localization layers.metadata.zs
Provides attribute properties of localization attributes.properties.zs
Provides types for localization attributes and attribute properties.types.zs

Landmarks can have relations to other map features like roads or lanes. These relations are expressed via an attribute map. Occupancy grids can also have relations to other map features like roads or lanes, being expressed via an attribute map as well.
