plot

Plot lane boundary points

Since R2024a

Syntax

plot(laneBoundaries)

plot(laneBoundaries,Name=Value)

axesHandle = plot(___)

Description

plot(laneBoundaries) plots all the lane boundary points in the input laneBoundarySegment, or laneBoundaryGroup object laneBoundaries.

plot(laneBoundaries,Name=Value) specifies options using one or more name-value arguments. For example, LaneBoundaryIDs=laneBoundaryIDs plots only the lane boundary points that belong to the specified lane boundary IDs laneBoundaryIDs.

axesHandle = plot(___) returns a figure handle as an axes object.

Note

This function requires the Scenario Builder for Automated Driving Toolbox™ support package. You can install the Scenario Builder for Automated Driving Toolbox support package from the Add-On Explorer. For more information about installing add-ons, see Get and Manage Add-Ons.

Examples

Plot Lane Boundaries in Lane Boundary Segment Object

Load lane boundary segment data into the workspace.

data = load("laneBoundarySegmentData.mat","lbsegment");

Display the lane boundary segment object.

data.lbsegment

ans = 
  laneBoundarySegment with properties:

       BoundaryIDs: [4×1 string]
    BoundaryPoints: {4×1 cell}
      BoundaryInfo: []
     NumBoundaries: 4
         NumPoints: 128
      GeoReference: []

Plot all lane boundary points in the loaded lane boundary segment object.

plot(data.lbsegment)

Select a lane boundary point in the figure and observe its relevant information, such as boundary ID.

Plot Lane Boundaries in Lane Boundary Group Object

Load lane boundary data into the workspace

data = load("laneBoundaryGroupData.mat","lbGroup");

Display the lane boundary group object.

lbGroup = data.lbGroup

lbGroup = 
  laneBoundaryGroup with properties:

      BoundarySegments: [2×1 laneBoundarySegment]
    SegmentConnections: {[1 2]  [4×2 string]}
        BoundaryGroups: [1×5 struct]
          GeoReference: []

Plot all lane boundary points in the loaded lane boundary group object.

plot(lbGroup)

Select a lane boundary point in the figure and observe its relevant information, such as boundary ID and segment index.

Input Arguments

laneBoundaries — Lane boundaries

laneBoundarySegment object | laneBoundaryGroup object

Lane boundaries, specified as a laneBoundarySegment or laneBoundaryGroup object.

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: plot(laneBoundaryPoints,LaneBoundaryIDs=laneBoundaryIDs) plots only the lane boundary points that belong to the specified lane boundary IDs laneBoundaryIDs.

LaneBoundaryIDs — Lane boundary IDs

N-by-1 string array

Lane boundary IDs, specified as an N-by-1 string array. N is the number of lane boundaries.

Data Types: string

Parent — Parent figure

Axes object

Parent figure, specified as an Axes object. If you specify this argument, the function plots the lane boundaries in an existing figure. Otherwise, the function creates a new figure and plots the lane boundaries in it.

You can return an Axes object when calling a plot function. For example, axesHandle = plot(laneBoundaries) creates an Axes object, axesHandle.

Data Types: string

Output Arguments

axesHandle — Figure handle

Axes object

Figure handle, returned as an Axes object.
