Digitalwerk has been developing a system for visualizing sensor and camera data for an OEM since 2018. The result is a central configuration that connects and visualizes camera data, signals and debug information.

The visualization system is used in the development cycle when validating highly automated driving functions (e.g. development of the Lane Dection or Passenger Recognition function).

Depending on the type, data must be visualized 2 dimensionally or 3 dimensionally. This allows the customer to see offline or live in the test vehicle whether the algorithms developed by him work reliably.

ADTF as a framework was particularly suitable for this task, as existing components could be used directly and missing functionality could be implemented and integrated via the standardized ADTF interfaces.

Digitalwerk has been supporting two OEMs in the development of the next measurement technology generations since 2019. The common goal of the respective projects, is to integrate and expand ADTF as a central unit in a tool chain in order to conveniently access, decode, process and visualize all bus data and debug interfaces with high performance.

Using ADTF, data and results from sensor data fusions were visualized in point clouds, areas and lanes in three-dimensional space. According to the requirements of the customer, the visualizations had to be designed in such a way that they could be dynamically reconfigured at runtime to meet the needs of the customer.

Within the measurement technology, raw data streams are recorded using ADTF in order to enable a realistic re-simulation or offline analysis within post-processing.

This allows results between live operation and simulation to be compared and validated.

The degree of networking between software components and their number has been increasing for years. This leads to the question of how software components can be tested as efficiently and promptly as possible.

The aim of Digitalwerks AUTOSAR sidekick is, to provide a solution for testing AUTOSAR software components via ADTF.

Digitalwerks AUTOSAR sidekick generates an access layer for the finished software component so that the component can be accessed directly from ADTF. This means that the component can be tested efficiently and effectively via ADTF using various test vectors at any stage. Integration into a system network or even complex residual bus simulations are no longer necessary.

The enormous and constantly increasing data rate in todays vehicle generations poses major challenges for all participants, involved in the development process. Depending on the type of data, the platforms, and requirements of the customer, specialized software solutions are used. Within these environments, the ADTF framework can either be directly linked to the tools or a data flow can be established via specially developed exports.

This direct and indirect degree of networking via internal as well as external Interfaces, enables a comfortable mixed operation which serves for analysis and verification. The individual steps within the data processing were developed so that they can also be integrated in fully automated and highly scaled cloud systems and executed in a pipeline.

The ADTF framework provides the corresponding applications, services and interfaces to realize the required formats, connections and environments with on-board resources.
