Merging a unreferenced laser scan with geo-referenced UAV photogrammetry

    Greetings,

    As long as you have enough overlaps between the drone images and laser scan it should connect properly and keep your geo-referencing. It is always a bonus to have and use GCP's though, just to make sure everything ends up well.

    This is an interesting topic.

    I've faced recently several cases where some laser scans of one survey are correlated to the images, but not all of them. We've tried intensity and RGB values, locked and draft position, no position at all, etc. We've tried GCPs, changing the images resolution : nothing seems to explain why some laser scans of the same area do match with the images and other don't.

    Debugging theses inconsistencies is awfully time consuming. And it's been 2 years 1/2 that we use RC every day.

    Some detailed recommendations from RC team would certainly be useful to the community, and duly appreciated! :)

    Sounds good Erik Kubiňan CR.

    We just finished the laser scan so we will try it once back in the office and let you know how it goes.

    Cheers,
