Create a label definitions table from a labelDefinitionCreatorMultiSensor object that you can import into the Multi-Sensor Labeler app.

Create an empty labelDefinitionCreatorMultiSensor object.

ldc = labelDefinitionCreatorMultiSensor;

Add a label called "Vehicle". Specify the label type as "Rectangle" and add a description to the label.

addLabel(ldc,"Vehicle","Rectangle",Description="Bounding box for the vehicle. Use this label for cars and buses.")

Add an attribute "IsCar" to the label "Vehicle". Specify the attribute type as "logical" with the value true and add a description for the attribute.

addAttribute(ldc,"Vehicle","IsCar","logical",true,Description="Type of vehicle")

Add an attribute "IsBus" to the label "Vehicle". Specify the attribute type as "logical" with the value false and add a description for the attribute.

addAttribute(ldc,"Vehicle","IsBus","logical",false,Description="Type of vehicle")

Create a label definitions table from the definitions stored in the object.

labelDefs = create(ldc)
labelDefs = 2×7 table

    {'Vehicle'}    Image         Rectangle    {'None'}    {'Bounding box for the vehicle. Use this label for cars and buses.'}    {0×0 char}    {1×1 struct}
    {'Vehicle'}    PointCloud    Cuboid       {'None'}    {'Bounding box for the vehicle. Use this label for cars and buses.'}    {0×0 char}    {1×1 struct}

Input Arguments

Label definitions, returned as a table with up to eight columns. The possible columns are Name, SignalType, LabelType, Group, Description, LabelColor, PixelLabelID, SemanticLabelID, and Hierarchy. This table specifies the definitions of labels, sublabels, and attributes for labeling ground truth data. For more details, see LabelDefinitions property of groundTruthMultiSensor object.
