Lidar ground truth label data
The groundTruthLidar
object contains information about lidar
ground truth labels. The data source used to create the object is a collection of lidar point
cloud data. You can create, export, or import a groundTruthLidar
object from
the Lidar Labeler app.
To export a groundTruthLidar
object from the Lidar
Labeler app, on the app toolstrip, select Export Labels > To Workspace. The app exports the object to the MATLAB® workspace. To create a groundTruthLidar
object
programmatically, use the groundTruthLidar
function (described
here).
returns an object containing lidar ground truth labels that can be imported into the
Lidar Labeler app.gTruth
= groundTruthLidar(dataSource
,labelDefs
,labelData
)
dataSource
specifies the source of the lidar point cloud
data and sets the DataSource
property.
labelDefs
specifies the definitions of ROI and scene labels
containing information such as Name
, Type
, and
Group
, and sets the LabelDefinitions
property.
labelData
specifies the identifying information, position,
and timestamps for the marked region of interest (ROI) labels and scene labels, and
sets the LabelData
property.
