Hi guys, I’m having some troubles creating a good quality 3D scan of a pipeline using my P34K and I’m hoping someone can assist with some troubleshooting for me please.
I understand that I could just fly a nadir mission and it would probably give some ok results, but for this I’m really wanting a detailed model showing the sides and underside supporting structure etc.
I flew a 200m length of a water pipeline, first run was scanning it at a low oblique angle (as I wanted to capture the footings and as much of the underside as I could), then I scanned back to my original start point but this time nadir from above, then lastly I did the side (oblique) scan of the other side. My thinking was that this should give me the best results as I was close (around 10m from the pipeline) and I was getting coverage of all angles.
Initially I ran the images through the ‘structure’ template on DD and the results were poor and patchy. Then I ran the same images through the ‘terrain’ template and it was less patchy but the accuracy of the form was terrible.
I’m wondering if my methodology was sound, but it was just that I did not have sufficient overlap on my imagery for the resulting model to be good. Or is there a another way that I should conduct my mission in order to get better results. Does anyone have any ideas they can share please?
I’ve uploaded some pics below, the first two are using the ‘structure’ template, the second two are using the ‘terrain’ template. My flight ID is: eb8bea2b26_THEAEROSCOOPENPIPELINE
Thanks in advance.
