ptCloud = getRegion(bpc,roi) returns all points in the blocked point cloud bpc in specified region roi.

[ptCloud,pointAttributes] = getRegion(___) returns additional point attribute information pointAttributes, using all input arguments from the previous syntax, if the input is a LAZ or LAS file.


collapse all

Create a blocked point cloud from a LAZ file.

pcfile = fullfile(toolboxdir("lidar"),"lidardata", ...
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.
