From this study can be concluded that using drones equipped with cameras a 3D model van be created of an incident on the rail. From the recordings, a 3D model van be made using photogrammetry. In this model it is possible to measure post distances with an estimated error of less than 1 centimeter. The distances between the laser scanner point cloud and the point cloud created with the drone are in 78% of cases smaller or equal to two centimeters. In order to further reduce the distances between the point clouds more photos from the bottom of the train.
