Assign RGB attributes to LIDAR data

Recommended Posts

Hello everbody,

does someone know to assign an RGB color to Lidar data from  specific ortophotos?

I'm testing Terrascan since the softwear has a tool to extract the color from an image, my problem is that i don't have a macrostep to run this process in a large number of files.

Thank you

thanks for your reply

The data is in .las format due to a previus process of  classification.

these large number of files ( ex. 1000) should get RGB attributes from specific ortos. I can do it in terrascan because is verry fast for one file, the problem is to do the same for 1000 pieces.

Hello, prv. Mihai!

You should use "extract colors from images" command from project -> tools.

But you need to make a project first and import some data into it. Do not forget to check "store color values" in project options and make sure you are using appropriate data storage format.

Once coloured, points could be exported via macro; as XYZRGB, i.e.

And - you may use raw images (non-rectified) with external orientation to make more accurate colouring on elevated objects.

Forgot to mention - it is TerraScan.
