partition
Description
Examples
Partition blockedPointCloudDatastore
and Read First Partition
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);
Partition the blocked point cloud datastore into two partitions, and create a new blockedPointCloudDatastore
object from the data in the first partition.
bpcdsp1 = partition(bpcds,2,1);
Read data and metadata from the first partition. Display the metadata.
while hasdata(bpcdsp1) [data,info] = read(bpcdsp1); disp(info) end
