I am pretty sure I don’t fully understand custom settings…or my workflow is just screwed up.
I am trying to do a model of a small lighthouse.
On my first try, I flew standard nadir and oblique patterns and the point cloud looks “ok” but none of the railings, that are visible in the point cloud, showed up in the textured model. I examined the pictures and notices that the railings are close to the same color as the water and maybe they just got lost in the stitching. Options: min-num-features: 10000, opensfm-depthmap-min-consistent-views: 4, camera-lens: brown, rerun-from: dataset
I went back out and flew again, taking more close up pictures and added them.
This time the point cloud as a LOT more garbage points but the railings and a small solar panel are fuller. BUT the textured model looks almost identical to the first run.
Default settings.
So I upgraded…re-ran the same pictures with these settings…
min-num-features: 10000, camera-lens: brown, opensfm-depthmap-min-consistent-views: 3, mesh-octree-depth: 12, pc-quality: ultra
got an error:

Apparently I don’t fully understand how masking works. It’s actually getting worse.
Here is the PC after masking the water and sky all all of my close-up pictures of the top part of the lighthouse.

I’ll probably get crucified for this, but…
I’ve never had good luck with textured maps in webodm. DroneDeploy and Pix4D generate better results on that front. However, textured maps and models aren’t a deliverable for me. I process ultra-high density point clouds and deliver that. It’s more accurate for architects to measure.
I’ve been fiddling for a few years now, and haven’t come up with a workflow to get these details in a texture.
Actually it’s texturing where I have my biggest “letdowns” as well on structures. I quite like the results on “landscape” projects…erosion, etc. I’ve always attributed it to me not understanding the settings. I often get better texturing results with Meshlab on structures.
I often wonder if the having the ability to do manual tie-points would help. I’ve seen it other paid programs (Pix4D) but not here
Hello everyone! I have the same problem!!
I want to share you a folder with a lot of photos about a wind turbine. There are orbital flights. I try to generate a 3D model but I can´t. Can anyone help me?
for the next run.
