Hi Everyone,
I was testing the PhotoScan in order to get a 3D model of crashed car and I need to admit that the results are good enough for further analysis.
But I am considering to apply close range photogrammetry to 3D reconstruction of road details (pavement, asphalt, ditches etc.). I know the UAV is the one of the solution but What about handheld non-metric camera?
Do you know some methodology (techniques) to prepare ground station for camera to get the best result after PhotoScan processing the data? How to pick station for camera? What about angles of camera axis? What if a road is sloping? The good practice is to taking photos along the parallel line to kerb using demanded overlapping or taking images in a circle (20-25°) from different ground stations?
I need to find some solution to 3D reconstruction of the road situation for forensics experts specialized in car accidents.
Thank you for taking part in this discussion.
