Open Live Script

Create a blocked point cloud from a LAZ file.

pcfile = fullfile(toolboxdir("lidar"),"lidardata", ...
  "las","aerialLidarData.laz");
bpc = blockedPointCloud(pcfile,[50 50]);

Specify a region in the point cloud and retrieve the data.

pcRegion = getRegion(bpc,[429745.02 429775.02 ...
                3679830.75 3679860.75 72.79 125.82]);

Plot the point cloud data from the specified region.

pcshow(pcRegion)

Figure contains an axes object. The axes object contains an object of type scatter.

Input Arguments

collapse all

Blocked point cloud, specified as a blockedPointCloud object.

ROI limits of the block, specified as a six-element row vector of form [xmin xmax ymin ymax zmin zmax], defining the range of the block.

Output Arguments

collapse all

Point cloud data from specified region, returned as a pointCloud object.

Point attributes, returned as a lidarPointAttributes object.
