Parking lot 3D environment
The Parking Lot scene is a 3D environment of a parking lot. The scene is rendered using RoadRunner.
To simulate a driving algorithm in this scene:
Add a Simulation 3D Scene Configuration block to your Simulink® model.
In this block, set the Scene source parameter to
Set the enabled Scene name parameter to
Explore Parking Lot Scene
Explore the 3D Parking Lot scene and inspect its dimensions by using a corresponding 2D top-view image of the scene.
You can use this image to inspect the scene before simulation and choose starting coordinates for vehicles. For details on using these images to select waypoints for path-following applications, see the Select Waypoints for Unreal Engine Simulation example.
Load the 2D spatial referencing object that corresponds to the scene. This
imref2d object describes the relationship between the pixels in the image and the world coordinates of the scene.
data = load('sim3d_SpatialReferences.mat'); spatialRef = data.spatialReference.ParkingLot
spatialRef = imref2d with properties: XWorldLimits: [-195.5000 8.9000] YWorldLimits: [-27.1000 177.3000] ImageSize: [5016 5016] PixelExtentInWorldX: 0.0407 PixelExtentInWorldY: 0.0407 ImageExtentInWorldX: 204.4000 ImageExtentInWorldY: 204.4000 XIntrinsicLimits: [0.5000 5.0165e+03] YIntrinsicLimits: [0.5000 5.0165e+03]
Display the image corresponding to the scene. Use the spatial referencing object to display the axes in the world coordinates of the scene. Units are in meters.
By default, the
imshow function displays Y-axis values that increase from top to bottom. To align with the Automated Driving Toolbox™ world coordinate system, set the Y-direction to
'normal' so that Y-axis values increase from bottom to top.
The image displays only the area of the scene containing the parking lot. The full scene has a length and width of 705.6 meters.
figure fileName = 'sim3d_ParkingLot.jpg'; I = imshow(fileName,spatialRef); set(gca,'YDir','normal') xlabel('X (m)') ylabel('Y (m)')
Zoom in on the origin of the scene. Place a marker at the origin.
xlim([-40 10]) ylim([-30 20]) hold on plot(0,0,'o','MarkerFaceColor','r','MarkerEdgeColor','k','MarkerSize',8) offset = 1; % px text(offset,offset,'(0,0)','Color','w','FontWeight','bold','FontSize',12) hold off
If you have the Automated Driving Toolbox™ Interface for Unreal Engine® 4 Projects support package, then you can modify this scene. In the Unreal Engine project file that comes with the support package, this scene is named

Version HistoryIntroduced in R2019b
R2022b: Scene rendered using RoadRunner
Starting from R2022b, the Parking Lot scene in the Unreal Engine 3D environment is rendered using RoadRunner. As a result, the locations of scene objects, including cones and parked vehicles, are moved from their pre-R2022b locations.
