Scenario Generation and Variation

Generate scenario from recorded real-world sensor data and create scenario variations from seed scenario

In automated driving applications, scenario generation is the process of building virtual scenarios from real-world vehicle data recorded from global positioning system (GPS), inertial measurement unit (IMU), camera, and lidar sensors. Automated Driving Toolbox™ provides functions and tools to automate scenario generation process. You can preprocess sensor data, extract roads, localize actors and get actor trajectories to create an accurate digital twin of a real-world scenario. Simulate the generated scenario and test your automated driving algorithms against real-world data.

To generate scenarios from recorded sensor data, download the Scenario Builder for Automated Driving Toolbox support package from the Add-On Explorer. For more information on downloading add-ons, see Get and Manage Add-Ons.

Scenario variation is the process of generating multiple variants from a seed scenario that is either manually created or generated from recorded sensor data. You can vary scene parameters, actor parameters, or event parameters of a seed scenario and provide your constraints to generate new scenarios. Use these scenario variations for safety assessment of different automated driving applications such as autonomous emergency braking (AEB), lane keep assist (LKA), and adaptive cruise control (ACC).

To generate scenario variations, download the Scenario Variant Generator for Automated Driving Toolbox support package from the Add-On Explorer. For more information on downloading add-ons, see Get and Manage Add-Ons.
