Trying to process a mesh of a site that has 700 images. I flew the site a few months back with 80% overlap and didn’t quite get the quality I wanted. Flew again with 90% overlap. Processed again with slightly better quality but still not great. I thought I would mix in some of the images from my first flight as this site is a memorial so nothing changes other than grass color. It’s all stone/concrete. After running for 20 hours (most of my projects have processed in 8 hours or less) webodm completes matching and does a few more things, and at the step where it starts to densify gives me a cannot process dataset error. Below is the error part of the task output.
My laptop specs are i-7 6-core with 32gb ram, 1tb ssd. Hard drive is not full and I haven’t had any issues running projects before. I’m guessing this is because I mixed in some images taken a month or so ago, but again it’s a concrete monument so it’s not like there is a huge difference with features, shadows, etc. Just different angles taken on different days. It just really sucks that after 20 hours of doing matching it just errors out. I adjusted the settings do High Quality, mesh-size 250000 and min-num-features to 20000, orthophoto-resolution .70 (I flew at 45 feet). Other than that all other settings default. I’ve had decent results with these settings before, this was the first time I had more than 500 images though.
