Display information about labels, sublabels, and attributes stored in a labelDefinitionCreatorMultiSensor object.

Load an existing label definition table.

labelDefFile = fullfile(toolboxdir("pointcloud"),"pcdata","labelDefsMultiSensor.mat");
ld = load(labelDefFile)
ld = struct with fields:
    labelDefs: [6×6 table]

Create a labelDefinitionCreatorMultiSensor object from the label definitions table.

ldc = labelDefinitionCreatorMultiSensor(ld.labelDefs)
ldc =
labelDefinitionCreatorMultiSensor contains the following labels:

	Car with 0 sublabels and 0 attributes and belongs to None group.	(info)
	LeftLane with 0 sublabels and 0 attributes and belongs to None group.	(info)
	Road with 0 sublabels and 0 attributes and belongs to None group.	(info)
	Sunny with 0 sublabels and 0 attributes and belongs to None group.	(info)
	Urban with 0 sublabels and 0 attributes and belongs to None group.	(info)

For more details about attributes and sublabels, use the info method.

Add an attribute "Color" to the label "Car". Specify the attribute type as "List" and add items to the list.

addAttribute(ldc,"Car","Color","List",{"Red","Green","Blue"});

Display the details of the updated labelDefinitionCreatorMultiSensor object.

Label definition creator for the multi-sensor workflow, specified as a labelDefinitionCreatorMultiSensor object.

Name of label, sublabel, or attribute in the ldc object, specified as a character vector or string scalar whose form depends on the type of name you specify.

  • To specify a label, use the form 'labelName'.

Example: info(ldc,"TrafficLight")

  • To specify a sublabel, use the form 'labelName/sublabelName'.

Example: info(ldc,"TrafficLight/RedLight")

  • To specify an attribute, use the form 'labelName/attributeName' or 'labelName/sublabelName/attributeName'.

Example: info(ldc,"TrafficLight/Active")

Example: info(ldc,"TrafficLight/RedLight/isOn")

Output Arguments
