blocksub2roi

Convert block subscripts to ROI limits

Since R2022a

Syntax

roi = blocksub2roi(bpc,blocksub)

roi = blocksub2roi(bpc,blocksub) converts the subscripts of a block to the ROI limits of that block in the blockedPointCloud object bpc.

Create a blocked point cloud from a LAZ file.

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

Convert the subscripts of a block to the ROI limits of that block.

roi = blocksub2roi(bpc,[2 2 1]);

Display the ROI limits of the block.

disp(roi)

Blocked point cloud, specified as a blockedPointCloud object.

Block subscripts, specified as a three-element row vector of positive integers.

Example: [2 3 1]

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

Introduced in R2022a
