Photogrammetry & Laser scanner matching

[a.bovero@inwind.it]

Hi all,
is there anybody who knows if there is a method for doublecheck phogrammetry with laser scanner?

I mean: I have low reso data from laserscanner and very detailed data from photogrammetry campaign. I'd like to know if there is a method for matching, doublechecking and/or realigning photogrammetry data using the pointcloud or mesh that comes from a laser scanner survey.

Thanks in advance!

Hi Alessandro,
definetly check out Cloudcompare. It has some awesome tools for deviation analysis between pointclouds/ meshes.
http://cloudcompare.org/

I use it all the time for aligning and comparing different pointclouds, it gives you a visualisation and different statistics.
