software to colorize lidar

[the0x275]

My current project involves working on an aerial LAS with ortho imagery and we were told to colorize it. Would anyone here know which software I can use for this task? Commercial is fine but if it is, could you recommend something that also work for terrestrial data?

Yeah, I've done stuff like this before. LP360 and ArcGIS Pro are both good at colorizing LAS files with ortho imagery, whether it's from planes or ground-based stuff. If you're looking for a free option and don't mind getting your hands dirty, CloudCompare works pretty well too.

What's the point density and how big is the project? Knowing that might help figure out which tool is the best fit for you.

Hi @theox275,

Great question! Colorizing a LAS file using ortho imagery is a common workflow in geospatial and 3D mapping projects. There are several software options you can use for this—both commercial and flexible enough to handle both aerial and terrestrial LiDAR data.

Here are a few tools commonly used by professionals:

1. LAStools – Specifically, lascolor.exe in LAStools is a fast and efficient utility for colorizing LAS/LAZ files using ortho imagery. It's widely used in the LiDAR industry and works well for both aerial and terrestrial point clouds. Note that it's free for non-commercial use but requires a license for commercial projects.
2. CloudCompare – This is a powerful open-source tool that can handle point cloud colorization. It supports various file formats and has plugins for custom workflows. While not as automated as LAStools, it's a solid option, especially for smaller datasets or manual refinement.
3. TerraScan (by Terrasolid) – A premium solution that's part of the Bentley MicroStation ecosystem. It's robust and ideal for large-scale projects with mixed datasets. TerraScan allows you to overlay ortho imagery and colorize both aerial and terrestrial LiDAR with high accuracy.
4. Pix4D Mapper or RealityCapture – If your workflow also includes photogrammetry, both tools offer features to colorize point clouds based on images and work well for integrated datasets. They are commercial but very effective.

Pro Tip: Make sure your ortho image and point cloud are perfectly aligned in terms of projection and georeferencing. Even small discrepancies can lead to inaccurate color mapping.

Cheer's,

If you want to colorize aerial LAS with ortho images, Pix4Dmapper is pretty decent, it works for both aerial and ground data. Agisoft Metashape is another good desktop option , and DroneDeploy is easy if you prefer cloud tools. Which kind of setup are you leaning toward?

You can use QGIS or ArcGIS for colorizing both aerial and terrestrial ortho imagery bcos both handle raster data well and offer good visualization tools
