CloudCompare forum

Hello,

I have a .laz point cloud file which I am trying to color with a .tif satellite image using CloudCompare 2.13.2. The original satellite imagery tile is way too large for my .laz file so I cut it to size in QGIS using the cut from an extent tool in QGIS' raster toolbox.

The issue I have is that when importing the.tif file into CC, the colors show up wrong, they're very vivid shades of RGB, but not the same I see in QGIS. I've watched multiple tutorials on the process of draping a point cloud file with realistic colors using satellite imagery but none of the ones I've watched had the .tif file show abnormal colors, they all have the normal "real life" colors as you would see in QGIS. I've inserted a screen capture of the layer I'm having issues with in CC in case it helps.

What am I doing wrong?

Thank you for your time.

From what I see in your screenshot, the 'colors' are not considered as RGB colors, but as a scalar field. Or the tiff file has some other bands than RGB:
- first, you can see in the 'Colors' combo-box in the tiff image properties if there's an 'RGB' source instead of 'Scalar field'
- if not, and you have 3 different scalar fields (this can be checked in the 'Scalar fields' section further down) then you can try to convert them to RGB (with 'Edit > Colors > From scalar fields') assuming they go from 0 to 255
