actorPoses
Positions, velocities, and orientations of actors in driving scenario
Description
returns the current poses (positions, velocities, and orientations) for all actors
in the driving scenario, poses
= actorPoses(scenario
)scenario
. Actors include
Actor
objects, Vehicle
objects, and
Barrier
segments, which you can create using the actor
, vehicle
and barrier
functions, respectively. Actor poses are in scenario
coordinates.
Examples
Create Driving Scenario with Multiple Actors and Roads
Create a driving scenario containing a curved road, two straight roads, and two actors: a car and a bicycle. Both actors move along the road for 60 seconds.
Create the driving scenario object.
scenario = drivingScenario('SampleTime',0.1','StopTime',60);
Create the curved road using road center points following the arc of a circle with an 800-meter radius. The arc starts at 0°, ends at 90°, and is sampled at 5° increments.
angs = [0:5:90]'; R = 800; roadcenters = R*[cosd(angs) sind(angs) zeros(size(angs))]; roadwidth = 10; road(scenario,roadcenters,roadwidth);
Add two straight roads with the default width, using road center points at each end.
roadcenters = [700 0 0; 100 0 0]; road(scenario,roadcenters)
ans = Road with properties: Name: "" RoadID: 2 RoadCenters: [2x3 double] RoadWidth: 6 BankAngle: [2x1 double] Heading: [2x1 double]
roadcenters = [400 400 0; 0 0 0]; road(scenario,roadcenters)
ans = Road with properties: Name: "" RoadID: 3 RoadCenters: [2x3 double] RoadWidth: 6 BankAngle: [2x1 double] Heading: [2x1 double]
Get the road boundaries.
rbdry = roadBoundaries(scenario);
Add a car and a bicycle to the scenario. Position the car at the beginning of the first straight road.
car = vehicle(scenario,'ClassID',1,'Position',[700 0 0], ... 'Length',3,'Width',2,'Height',1.6);
Position the bicycle farther down the road.
bicycle = actor(scenario,'ClassID',3,'Position',[706 376 0]', ... 'Length',2,'Width',0.45,'Height',1.5);
Plot the scenario.
plot(scenario,'Centerline','on','RoadCenters','on'); title('Scenario');

Input Arguments
scenario
— Driving scenario
drivingScenario
object
Driving scenario, specified as a drivingScenario
object.
Output Arguments
poses
— Actor poses
structures | array of structures
Actor poses, in scenario coordinates, returned as a structure or an array of structures. Poses are the positions, velocities, and orientations of actors.
Each structure in poses
has these fields.
Field | Description |
---|---|
ActorID | Scenario-defined actor identifier, specified as a positive integer. |
Position | Position of actor, specified as a real-valued vector of the form [x y z]. Units are in meters. |
Velocity | Velocity (v) of actor in the x- y-, and z-directions, specified as a real-valued vector of the form [vx vy vz]. Units are in meters per second. |
Roll | Roll angle of actor, specified as a real-valued scalar. Units are in degrees. |
Pitch | Pitch angle of actor, specified as a real-valued scalar. Units are in degrees. |
Yaw | Yaw angle of actor, specified as a real-valued scalar. Units are in degrees. |
AngularVelocity | Angular velocity (ω) of actor in the x-, y-, and z-directions, specified as a real-valued vector of the form [ωx ωy ωz]. Units are in degrees per second. |
For full definitions of these structure fields, see the actor
, vehicle
and barrier
functions.
