Integrate Scenes with MATLAB and Simulink
You can integrate RoadRunner scenes with MATLAB and Simulink to provide a workflow for developing and testing automated driving algorithms in a virtual environment. This integration enables you to create detailed, photo-realistic scenes in RoadRunner and use them in MATLAB and Simulink for algorithm development and testing.
An automated driving workflow encapsulates the entire process from data import and transformation to analysis, simulation, and visualization. You can create RoadRunner scenes and export them to file formats that are compatible with Simulink for scenario simulation. You can then use these scenes to test your driving algorithms in dynamic scenario environments containing vehicles, sensors, and weather conditions.
You can integrate MATLAB and Simulink with scenes at the following different stages of an automated driving workflow
Scene Import and Export:
You can design scenes in RoadRunner from scratch using a graphical interface and the RoadRunner Asset Library, which contains 3D models and assets. You can also import data from a variety of formats, such as ASAM OpenDRIVE®, and Zenrin SD Maps. If you are working with HD map data like Here or TomTom or your own custom formats, you can import these maps into RoadRunner using RoadRunner Scene Builder
RoadRunner also provides MATLAB functions for performing common workflow tasks such as opening, closing, and saving scenes and projects and importing and exporting scenes.
The scenes you create in RoadRunner can then be exported to file formats like ASAM OpenDRIVE and Filmbox, which are compatible with MATLAB and Simulink.
Automation: Once you integrate RoadRunner scenes with MATLAB, you can use MATLAB scripts to automate repetitive tasks such as bulk export, running simulations or updating models based on RoadRunner data.
Algorithm Design and Analysis: Using MATLAB and Simulink, you can simulate driving applications to mimic real-world behaviors such as adaptive cruise control, emergency braking, lane change, platooning, and parking. Simulation results from these behaviors can influence subsequent simulations or model adjustments in RoadRunner, creating an iterative process with a high-fidelity algorithm.
Therefore, using this integration workflow, you can automate data handling and processing, reducing manual effort and the potential for errors. Your algorithms can easily adapt to handle larger datasets or more complex simulations as projects grow. This also implies that processes are consistent and an be replicated for different datasets or projects.
