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]);

Collect the blocks and point attributes of the blocked point cloud, and assemble them into a pointCloud object and lidarPointAttributes object, respectively.

[ptCloud,ptAttr] = gather(bpc);

Display the assembled point cloud. Specify the color based on the classification attributes.

pcshow(ptCloud.Location,ptAttr.Classification)

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.

Output Arguments

collapse all

Assembled point cloud, returned as a pointCloud object.

Note

When the class of underlying source of input blocked point clouds is "struct", then the function returns an array of structures instead of pointCloud object. The size of array matches the SizeInBlocks property value of input blocked point clouds.

Since R2024a

Assembled point attributes, returned as a lidarPointAttributes object.
