This is an overview of image post processing using VisualSFM and CMPMVS open source photogrammetry software. I flew a mapping mission with my UAV (APM 2.5 on a skywalker platform), capturing 251 images of the Oceanside Marine Study area. The mission was flown 250ft altitude in a “lawnmower” pattern generated using Mission Planner GCS.
I used all images in post processing whether they were clear or blurry, orthogonal or oblique. I wanted to test the process with captured data “as is” and see what the output would look like, knowing that I can improve the inputs from future missions. The process was very exciting and the outputs are to me, very impressive.
As many of you know, my intent is to solidify a workflow for UAV mapping that is 100% open source. I am making good progress and I believe this ill be feasible. However, I have a long way to go. Please be patient with me and I promise to share the resulting workflow and all necessary steps to everyone.
