driving.scenario.bicycleMesh

Mesh representation of bicycle in driving scenario

Syntax

mesh = driving.scenario.bicycleMesh

Description

mesh = driving.scenario.bicycleMesh creates a mesh representation of a bicycle as an extendedObjectMesh object, mesh.

Examples

Generate Lidar Point Cloud by Using Bicycle Mesh

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

Create and show the prebuilt bicycle mesh.

mesh = driving.scenario.bicycleMesh;
egoMesh = driving.scenario.carMesh;
figure
show(mesh)

ans = 
  Axes with properties:

             XLim: [-0.5000 0.5000]
             YLim: [-0.2000 0.2000]
           XScale: 'linear'
           YScale: 'linear'
    GridLineStyle: '-'
         Position: [0.1300 0.1100 0.7750 0.8150]
            Units: 'normalized'

  Show all properties

Create a driving scenario.

s = drivingScenario;

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

road(s,[0 0 0; 30 0 0],'Lanes',lanespec([1 1]));

Add a car as an ego vehicle and a bicycle as a non-ego actor.

egoVehicle = vehicle(s,'ClassID',1,'Mesh',egoMesh);
bicycle = vehicle(s,'Position',[15 2 0],'Yaw',180,'ClassID',3,'Mesh',mesh);
smoothTrajectory(egoVehicle,[1 -2 0; 21.3 -2 0],20);

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

figure;
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
end

Output Arguments

mesh — Mesh representation of bicycle

extendedObjectMesh object

Mesh representation of bicycle, returned as an extendedObjectMesh object. The origin of the mesh is located at its geometric center.

You can develop your own meshes by using this prebuilt bicycle mesh as a starting point. At the MATLAB^® command line, enter:
