Read Data and Metadata from blockedPointCloudDatastore
Create a blocked point cloud.
pcfile = fullfile(toolboxdir("lidar"),"lidardata", ... "las","aerialLidarData.laz"); bpc = blockedPointCloud(pcfile,[300 300]);
Create a blockedPointCloudDatastore
from the blocked point cloud.
bpcds = blockedPointCloudDatastore(bpc);
Read data and metadata from the blockedPointCloudDatastore
. Display the metadata.
while hasdata(bpcds) [data,info] = read(bpcds); disp(info) end

Input Arguments
bpcds
— Blocked point cloud datastore
blockedPointCloudDatastore
object
Blocked point cloud datastore, specified as a
blockedPointCloudDatastore
object.
Output Arguments
b
— Data from blockedPointCloudDatastore
cell array
Data from the blockedPointCloudDatastore
, returned as a cell
array of block data. The length of the cell array is equal to the value of the
ReadSize
property of the
blockedPointCloudDatastore
object.
info
— Metadata from blockedPointCloudDatastore
structure
Metadata from the blockedPointCloudDatastore
, returned as a
structure with these fields. If the value of the ReadSize
property of
the blockedPointCloudDatastore
object is greater than 1, these fields
are arrays.
Field | Description |
---|---|
ROI | ROI of the block, specified as a six-element numeric row vector in the order [xmin xmax ymin ymax zmin zmax]. |
| Block subscripts of the current block. |
PCNumber | Index into the |
PointAttributes | Attributes for each point, specified as a |
BlockSize | Value of the |
Version History
Introduced in R2022aR2024b: Read subscripts of current block
The function returns the subscripts of the current block in the info
output
argument.
