Syntax

lbsegmentUpdated = resamplePoints(lbsegment,numSamples)

Description

Add-On Required: This feature requires the Scenario Builder for Automated Driving Toolbox add-on.

lbsegmentUpdated = resamplePoints(lbsegment,numSamples) resamples the lane boundaries in the input laneBoundarySegment object lbsegment to the specified number of lane boundary points numSamples, and returns an updated laneBoundarySegment object, lbsegmentUpdated.

This example uses:

Open Live Script

Load lane boundary segment data into the workspace.

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

Display the loaded lane boundary segment object.

lbsegment = data.lbsegment
lbsegment = 
  laneBoundarySegment with properties:

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

Resample the number of lane boundary points to 20 for each lane boundary in the lane boundary segment object. Display the resampled lane boundary segment object.

lbsegment = resamplePoints(lbsegment,20)
lbsegment = 
  laneBoundarySegment with properties:

       BoundaryIDs: [4×1 string]
    BoundaryPoints: {4×1 cell}
      BoundaryInfo: []
     NumBoundaries: 4
         NumPoints: 20
      GeoReference: []

Input Arguments

collapse all

Lane boundary segment, specified as a laneBoundarySegment object.

Number of lane boundary sample points, specified as an integer greater than 2.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

Output Arguments

collapse all

Updated lane boundary segment, returned as a laneBoundarySegment object.

The returned laneBoundarySegment object lbsegmentUpdated contains the resampled lane boundary points of the input laneBoundarySegment object lbsegment.
