driving.scenario.jerseyBarrierMesh

Add the prebuilt Jersey barrier mesh to a driving scenario. Then, use lidarPointCloudGenerator System object™ to generate a point cloud of the Jersey barrier mesh.

Create and show the prebuilt Jersey barrier mesh.

mesh = driving.scenario.jerseyBarrierMesh;
show(mesh);

Create a driving scenario.

s = drivingScenario;

Add a straight road to the driving scenario. The road has one lane in each direction.

road1 = road(s, [0 0 0; 25 0 0], 'Lanes', lanespec([1 1]));

Add a Jersey barrier to the road along the right edge.

barrier(s, road1, 'Mesh', mesh); 

Add a car as an ego vehicle and as a non-ego actor and apply the car mesh to both using driving.scenario.carMesh.

carMesh = driving.scenario.carMesh;
egoVehicle = vehicle(s,'ClassID',1,'Mesh',carMesh);
smoothTrajectory(egoVehicle,[1 -2 0; 21.3 -2 0], 20);
car = vehicle(s,'Position',[15 2 0],'Yaw',180,'ClassID',1,'Mesh',carMesh);

Plot the driving scenario. Set name-value pair 'Meshes','on' to show the meshes of the actors in the plot.

plot(s,'Meshes','on');

Create a lidarPointCloudGenerator System object. Set the actor profiles of the System object to those in the driving scenario.

lidar = lidarPointCloudGenerator;
lidar.ActorProfiles = actorProfiles(s);

Generate a lidar point cloud of the driving scenario.

player = pcplayer([-20 20],[-10 10],[0 4]);
while advance(s)
  tgts = targetPoses(egoVehicle);
  rdmesh = roadMesh(egoVehicle);
  [ptCloud, isValidTime] = lidar(tgts,rdmesh,s.SimulationTime);
  if isValidTime
      view(player,ptCloud);
  end
