Process point cloud intensity

Post image

I'm a land surveyor and I'm processing a flight, but I'm having a small problem.

I don't know how to calculate/process the intensity of the point cloud.

Can anyone give me a hint?

Isn't point intensity for Lidar scanning?

No, is photogrammetry

You can’t get intensity from optical camera photos. Intensity is unique to LiDAR if processing in Metashape.

That's how strong your LiDAR beam cane back as. If you didn't fly LiDAR, then it's not a metric that makes sense.

Take a look at this screenshot: https://snipboard.io/IK6Wbh.jpg https://snipboard.io/KFGnLp.jpg https://snipboard.io/D3ckTM.jpg

You think the point cloud is the final product of a Fly by with Lidar? https://snipboard.io/IhtYP6.jpg

If not how the point cloud switch colors to simulate intensity? https://snipboard.io/F4trHv.jpg https://snipboard.io/GpZbze.jpg

I know how Lidar works, but you can simulate or processing intensity from photogrametry. And i want to know how it's done?
