What is AURELION?
AURELION is a flexible software solution for sensor simulation and visualization. It enables you to integrate realistic sensor data into your processes for developing, testing, and validation of perception and driving functions. The same models can be used throughout various phases of development, for example in hardware-in-the-loop (HIL), software-in-the-loop (SIL), and vehicle-in-the-loop (VIL).
- Highly integrated in dSPACE simulation tools make the integration of AURELION quick and easy
- Our sensor simulation models make sure that you get the highest quality while still meeting your real-time demands
- Open interface to integrate custom sensor models brings the simulation even closer to reality
- Flexible integration of AURELION in third-party simulation brings our sensor simulation into your environment
Application Areas for AURELION
AURELION is suitable for a wide range of use cases and configurations. It can be used throughout various phases of development, for example, in hardware-in-the-loop (HIL) tests, software-in-the-loop (SIL) tests, vehicle-in-the-loop (VIL) tests, and for parallel validation in the cloud.
Examples of application fields:
- Automotive, autonomous vehicles, ADAS
- Automated mobile robots
Key Benefits for Sensor Simulation
The 3D rendering engine, the high-precision dSPACE simulation models, realistic 3D assets, and high-resolution material information allow for the accurate simulation of automotive sensors and environments under different weather and lighting conditions.
Camera Sensor Model
Realistically simulate a camera with a rectilinear or fish-eye lens and the corresponding sensor environment.
- High-fidelity graphics, lighting effects, and configurable realistic lens profiles
- Options for image modification and failure injection
- Configurable color filter for outputting raw sensor data
- Use ground truth information such as semantic segmentation, optical flow, and 2D bounding boxes to test and validate your algorithms
Radar Sensor Model
Simulate highly realictic synthetic radar data for all injection layers in real time.
- Channel impulse response, raw data, detection lists, and object lists output available
- Radar-optimized materials and multipath raytracing ensure effects as in real-world measurements (e.g. ghost targets)
- Adaptive ray launching guarantees accurate results and optimal performance even in multi-antenna setups
Lidar Sensor Model
Realistically simulate a lidar sensor and the corresponding sensor environment.
- Outputs a point cloud with realistic calculation of reflectivity values based on lidar-specific materials
- Support for scanning and flash-based sensors
- Realistic motion distortion effects with configurable time offsets for each ray
In order to develop and test computer vision, it is necessary to add ground truth information to sensor data. On the one hand, they are used for automatic tests of perception algorithms and on the other hand, they can also be used to train neuronal networks. Compared to ground truth data from real data, AURELION is generating the different ground truth variants pixel-perfect and for free. For every category, such as pedestrians, cars, and traffic signs.
- Special ground truth output available for camera, radar, and lidar
- The output is automatically parametrized to fit to your sensors
- Synchronized to the raw sensor data ground truth can easily be obtained via a C API
2D Bounding Boxes
2D bounding boxes are two-dimensional boxes that enclose objects in the camera sensor. They can be used to automatically test if your perception algorithm correctly identifies the available objects in your scene. The information is given as binary data so you can use the information for automatic tests in your building pipeline.
- Parameterized for your camera sensor to give out pixel-perfect
- Also includes information about the class and instance of every object
- Filtered for the type of objects you need
- Can be configured to integrate or discard obscured areas
The semantic segmentation of images included in AURELION provides pixel-level annotations to image regions. For artificial intelligence testing and training, especially for autonomous driving, this information can be used to help neural networks learn which patterns or textures belong to which semantic class of objects.
Subsequently, such networks can be implemented for use cases as diverse as image generation, domain adaptation, lane detection, or drivable area detection.
- Customizable categories
- Same categories across camera, radar, and lidar
- Output category ID and instance ID
Ground Truth for Active Sensors
Ground truth is also available for our active sensors like radar and lidar. This includes e.g. information about the category and instance for each detection of a radar sensor and each point within a point cloud. This information can easily be obtained and used to train neuronal networks.
- Category IDs and instance IDs are identical across every sensor to identify sensors across the sensor data easily
- Different output modes require different kind of ground truth information (obtain them easily via a C API)
With our software, we offer support for standards like OpenScenario and OpenDrive, allowing us to automatically generate a 3D environment for you. This saves you time and effort, allowing you to focus on what matters most - your simulation.
- We provide tools to let you modify the road and also add 3D assets to the environment
- Roads and terrain are automatically generated based on OpenDrive files
- Our 3D asset library includes sensor specific materials for sensor-realistic simulation
- For a quick start, we provide multiple high-fidelity environments across urban and highway areas
Various Customization Options
We understand that every simulation is unique, and sometimes you need to modify the road or 3D environment to meet your specific needs. That's why our software also provides you with the tools to make those modifications, giving you the flexibility and control to create a customized environment that meets your exact requirements.

What our customers say
With the dSPACE simulation solution, we have a flexibly configurable way to efficiently and reliably check the correct functioning of sensors and driver assistance systems of real vehicles in our test centers.
Thanks to the sensor-realistic simulation in AURELION, we were able to take into account, for example, the usual external influences such as multipath reflections due to construction site situations or peripheral buildings as well as influences in city traffic in a wide variety of variations during the development of our Blind Spot Information Systems.
dSPACE’s solution competence in simulation and validation completely convinced us and helped us to efficiently put our ambitious autonomous street sweeper project into practice.
The sensor-realistic simulation models from dSPACE make it possible to generate raw sensor data from complex 3-D scenarios.
With the sensor-realistic camera model, we can reliably simulate highly complex test tasks virtually.
Certified According to ISO 26262
AURELION was certified by TÜV SÜD according to ISO 26262 for safety-relevant systems in motor vehicles. The tool is thus suitable to be used in safety-related development projects according to ISO 26262:2018 for any automotive safety integrity level (ASIL).
This means: Vehicle manufacturers and suppliers can exclude AURELION from the ISO 26262 qualification of their entire processes and can concentrate on proving the functional safety of their own process chains.
Latest Version 23.3
The new version introduces multiple usability improvements across AURELION and AURELION Manager to make your workflows even swifter.
- Logging System in AURELION Manager
- Composite View Configuration in AURELION Manager
