Object Detection in a LIDAR File of a Test drive with a LIDAR system on a train through a track
Posted: Tue Aug 28, 2018 8:10 am
Hello I am new here and work in a thesis for the first time with a LIDAR file and thus with CloudCompare. I have a LAS-file which reflects a test drive on a LOK. The goal is to automatically detect objects in this file, such as signals or Switches and stuff like this. Only I have several problems there.
1st problem was that the file was 100 GB in size, which is why I have now divided these into "tiles" using LAStile to work well with it. I think that's a solution that will be enough for this time.
My bigger second problem i have right now is, the problem that there is an LOK artifact throughout the ride, which makes evaluation difficult, so I now have to find a solution to how to remove that "Fault".
I have to fixed description of the fault with maybe the coordinates. But the problem is, i miss the trajectory in the file and when i view the tiles in CloudCompare. Is there a way to define this trajectory by myself?
Can I set the center of the traveled route in CloudCompare and then always filter out the same interference using fixed distances and Fixed points in distance to the trajectory?
I hope I could describe my problem understandable and it is not too banal, have a great day!(:
