Z V) used by Automated Driving Toolbox is anchored to the ego vehicle. Automated Driving Toolbox uses the right-handed Cartesian world coordinate system defined in ISOĨ855, where the Z-axis points up from the ground. Localization, mapping, and driving scenario simulation. A world coordinate system is important in global path planning, Each axis is positive in the clockwise direction, when looking in the positive. World Coordinate SystemĪll vehicles, sensors, and their related coordinate systems are placed in the worldĬoordinate system. The vehicle coordinate system follows the ISO 8855 convention for rotation. Depending on the application, a vehicle coordinate frame is defined as follow : X axis is pointing in Forward direction, Z axis is pointing Down, and Y axis. Information on specific differences and implementation details in the 3D simulationĮnvironment using the Unreal Engine ® from Epic Games ®, see Coordinate Systems for Unreal Engine Simulation in Automated Driving Toolbox. These coordinate systems apply across Automated Driving Toolbox functionality, from perception to control to driving scenario simulation. System, typically used to calibrate camera sensors. Pattern: A checkerboard pattern coordinate Locations in spatial coordinates are expressed in units of 2 illustrates the relationship between the local ENU coordinates, the vehicle coordinates and. Spatial: Specific to an image captured by aĬamera. in the navigation coordinate system, i is the frame index. Sensor: Specific to a particular sensor, such Typically, the vehicle coordinate system is placed on the ground right below the Which all vehicles and their sensors are placed. World: A fixed universal coordinate system in
