I am working on a number of projects consisting of long narrow stone jetties or breakwaters that are surrounded on all sides by water. The structures are about 3,000 ft long and 100 ft wide. They have been photographed using a UAS with both nadir and oblique images in order to cover the top and sides of the wall. I have also incorporated survey grade targets or ground control points. I’m hoping someone has some best practices or tips they could share on getting things to line up in this scenario. My end goal is to end up with a detailed textured model, DEM, and orthoimage.
After a lot of messing around and adding control points I finally got it to look correct, not have a banana effect, and create a decent looking model. But I’m still not happy with the results and time it took me to get to this point when compared to the software I previously used.
Looking for suggestions with these Issues:
- Textured “sweet” model has small flakes or pieces everywhere that make it look bad. See attached image.
*Texture does not seem as defined or detailed as I expected. The pictures look much better. Is there a way to only texture using certain images perhaps?
*The orthoimage istops at the model, is there a way to extend the model on a set plane in order for the software to project the ortho onto the areas of water. In many instances there is information below the water that is important to capture in the orthoimage.
*Is there a way to set the bottom of the working plane to a set elevation in order to clip out or prevent creating data below or above that know plane?
Attached are a few screen shots of my project and results so far.
