R2026b

(To be removed) Lidar label type enumerations for labeling

Since R2022a

lidarLabelType will be removed in a future release. Use the labelType (Computer Vision Toolbox) enumeration instead. For information on updating your code, see Version History.

Description

The lidarLabelType enumeration enables you to specify the voxel labels used in the Lidar Labeler app. When creating label definitions by using a labelDefinitionCreatorLidar object, use this enumerations to create label definitions of voxel type. When selecting labels from a groundTruthLidar object, use these enumerations to select labels of voxel type.

Creation

Syntax

lidarLabelType('Voxel')

Description

lidarLabelType('Voxel') creates a voxel region of interest (ROI) label type for labeling point cloud data. You can also use the programmatic format, lidarLabelType.Voxel.

Object Functions

isROI (Computer Vision Toolbox)	Determine if label types are ROI labels
isScene (Computer Vision Toolbox)	Determine if label types are Scene labels

Examples

Specify Label Types Using Lidar Label Definition Creator

Create a lidar label definition creator object.

ldc = labelDefinitionCreatorLidar();

Add labels named "Road", "Bike" with the label types specified as line, cuboid, respectively.

addLabel(ldc,'Road',labelType.Line);
addLabel(ldc,'Bike',labelType.Cuboid);

Create voxel labels named as "Car" and "Tree".

addLabel(ldc,'Car',lidarLabelType.Voxel);
addLabel(ldc,'Tree',lidarLabelType.Voxel);

Display the details of the definitions stored in the lidar label definition creator object.

ldc

ldc = 
labelDefinitionCreatorLidar contains the following labels:

	Road with 0 attributes and belongs to None group.	(info)
	Bike with 0 attributes and belongs to None group.	(info)
	Car with 0 attributes and belongs to None group.	(info)
	Tree with 0 attributes and belongs to None group.	(info)

For more details about attributes, use the info method.

Version History

Introduced in R2022a

R2026b: To be removed

The lidarLabelType enumeration will be removed in a future release. Use the labelType (Computer Vision Toolbox) enumeration instead. The labelType enumeration is used with the labelDefinitionCreatorMultiSensor object and the Multi-Sensor Labeler app.
