How to get rosbag output file to create a georeferenced las file (Not issue)? #1

Wondering how to get rosbag output file to create georeferenced las file?

Using LivoxViewer?

Livox-SDK commented 4 years ago

Hi ns-1m,

We will support the las file output later. Now we support the pcd file output and you can do the file transform.

HI LIvox Dev Team

Is the output "pcd file output" georeferenced?

Any instruction how to "transform" the "pcd file output" to georeferenced las file.

What is the software we have to use?

What other file will be output aside from the "pcd file" that would be used to georeferenced the pcd or las file?

Only georeferenced las file is useful for UAV LiDAR mapping and survey.

Hi ns-1m,

The pcd file only include the point cloud information.

Due to some regulations, we temporarily do not provide raw data(include geographic information).

We will support the las file output in next version, if you want to get georeferenced las file now you need to save the geographic information and adapt las format in the mapping code.

OK.

I just wait for further documentation on this project.

Hii, I am new to this field of pointclouds, using this sensor setup on UAV for conducting survey in forest. As far from my understanding this package takes timesynchronized data from INS,GPS and lidar inorder to georeference the pointcloud and registration of pointclouds is also done in the process. Finally it outputs a map with georeferenced pointcloud. Please correct me if my understanding is wrong.

If my understanding is correct, how can I get a georeferenced pointcloud in .las format?

Thanks, Krishna.

Hello. Have you managed to find solutions for linking data to geographical coordinate systems?
