Laser Coloring Technology
The fusion of laser data and CCD image means finding RGB pixel values of the points in the CCD image which correspond to the laser data and appluing the pixel values to the laser data.
Firstly, we transformed the laser data to a DEM image. Next, we found corresponded points in the DEM and CCD images. Finally, we set up the DLT model and applied fusion.
Result showed that these images after fusion show color closer to the reality and we can make a more realistic 3D road images with interpolation.
