Syntax

plotCoverageArea(caPlotter,position,range,orientation,fieldOfView)

Description

plotCoverageArea(caPlotter,position,range,orientation,fieldOfView) displays the coverage area of an ego vehicle sensor on a bird's-eye plot. Specify the position, range, orientation angle, and field of view of the sensor. The coverage area plotter, caPlotter, is associated with a birdsEyePlot object and configures the display of sensor coverage areas.

Create a bird's-eye plot with an x-axis range from 0 to 90 meters and a y-axis range from –35 to 35 meters.

bep = birdsEyePlot('XLim',[0 90],'YLim',[-35 35]);

Figure contains an axes object. The axes object with xlabel X (m), ylabel Y (m) is empty.

Create a coverage area plotter for the bird's-eye plot.

caPlotter = coverageAreaPlotter(bep,'DisplayName','Radar coverage area');

Figure contains an axes object. The axes object with xlabel X (m), ylabel Y (m) contains an object of type patch. This object represents Radar coverage area.

Display a coverage area that has a 35-degree field of view and a 60-meter range. Mount the coverage area sensor 1 meter in front of the origin. Set the orientation angle of the sensor to 0 degrees.

mountPosition = [1 0];
range = 60;
orientation = 0;
fieldOfView = 35;

Plot the coverage area.

plotCoverageArea(caPlotter,mountPosition,range,orientation,fieldOfView);

Figure contains an axes object. The axes object with xlabel X (m), ylabel Y (m) contains an object of type patch. This object represents Radar coverage area.

Create a bird's-eye plot with an x-axis range from –100 to 100 meters and a y-axis range from –100 to 100 meters

bep = birdsEyePlot('XLim',[-100 100],'YLim',[-100 100]);

Figure contains an axes object. The axes object with xlabel X (m), ylabel Y (m) is empty.

Create coverage area plotters with unique display names and fill colors for each sensor location on the vehicle.

rearLeftPlotter = coverageAreaPlotter(bep,'DisplayName','Rear left','FaceColor','r');
rearRightPlotter = coverageAreaPlotter(bep,'DisplayName','Rear right','FaceColor','b');
frontLeftPlotter = coverageAreaPlotter(bep,'DisplayName','Front left','FaceColor','y');
frontRightPlotter = coverageAreaPlotter(bep,'DisplayName','Front right','FaceColor','g');

Figure contains an axes object. The axes object with xlabel X (m), ylabel Y (m) contains 4 objects of type patch. These objects represent Rear left, Rear right, Front left, Front right.

Set the positions, ranges, orientations, and fields of view for the sensors. The sensors have a maximum range of 90 meters and a field of view of 30 degrees. Plot the coverage areas.

plotCoverageArea(rearLeftPlotter,[0 0.9],90,120,30);
plotCoverageArea(rearRightPlotter,[0 -0.9],90,-120,30);
plotCoverageArea(frontLeftPlotter,[2.8 0.9],90,60,30);
plotCoverageArea(frontRightPlotter,[2.8 -0.9],90,-60,30);

Figure contains an axes object. The axes object with xlabel X (m), ylabel Y (m) contains 4 objects of type patch. These objects represent Rear left, Rear right, Front left, Front right.

Input Arguments

Coverage area plotter, specified as a CoverageAreaPlotter object. This object is stored in the Plotters property of a birdsEyePlot object and configures the display of coverage areas in the bird's-eye plot. To create this object, use the coverageAreaPlotter function.

Position of the sensor in vehicle coordinates, specified as a real-valued vector of the form [XOriginOffset YOriginOffset]. Units are in meters.

  • XOriginOffset specifies the distance that the sensor is in front of the origin.

  • YOriginOffset specifies the distance that the sensor is to the left of the origin.

The origin is located at the center of the rear axle, as shown in this figure of the vehicle coordinate system.

Vehicle with X-axis, Y-axis, and origin labeled

Range of sensor, specified as a positive real scalar. Units are in meters.

Orientation angle of the sensor relative to the X-axis of the ego vehicle, specified as a real scalar. Units are in degrees. orientation is positive in the counterclockwise direction (to the left).

Field of view of the sensor coverage area, specified as a positive real scalar. Units are in degrees.
