Point Cloud Data

PreviousControlled Environment phenotype dataNextHow to Access Data

Last updated 5 years ago

Summary

3D point cloud data is collected using the Fraunhofer 3D laser scanner. Custom software installed at Maricopa converts .png output to the .ply point clouds. The .ply point clouds are converted to georeferenced .las files using the 3D point cloud extractor

Level 1 data products are provided in both .las and .ply formats.

For each scan, there are two .ply files representing two lasers, one on the left and the other on the right. These are combined in the .las files.

Sensor information

For details about using this data via Clowder or Globus, please see section.

Data access

Data is available via Clowder, Globus, and Workbench.

  • Clowder:

  • Globus or Workbench File System:

    • LAS /sites/ua_mac/raw_data/laser3D_las

    • PLY /sites/ua_mac/raw_data/laser3D

Computational pipeline

Raw sensor output (PLY) is converted to LAS format using the ply2las extractor

Known issues

The position of the lasers is affected by temperature. We plan to add a correction for temperature that will adjust for this effect. See
