Procedures:
Important:
First, you will need your point cloud to match perfectly with your orthoimage. Both should have the same Coordinate Reference System. If they vary, the RGB values will not be applied correctly.
File and Software Requirement:
- Orthoimage with RGB data in .tif format.
- Pointcloud in .las format.
- Download Lastools open source using the .zip file: https://rapidlasso.com/lastools/
1. Once the Lastools.zip file has been saved in your computer, extract the file into your desired directory.
2. Copy both the pointcloud and orthoimage into a folder in the same directory as Lastools.
3. Use your terminal in Windows, use the change directory (cd) command to navigate to your folder where Lastools is located, and go to the bin folder (see below).
4. Locate the folder directories for the pointcloud and ortho. Use the following command:
lascolor -i <input.las> -image <orthophoto.tif> -o <output.las>
Tips:
- Drag and drop the Poincloud and orthoimage into the command prompt. Doing so will allow the terminal to autodetect the location of these files.
- Be mindful of where the new output point cloud will be stored.
Example:
5. Open the newly generated point cloud to see if the color has been applied.
