I have processed a few maps, trying to obtain the best image quality for OrthoPhotos and 3D models to determine feasibility using in a project. I am using a DJI Mavic 2 pro, with droneDeploy to create the flight mission, and then processing the collected data using WebODM on a linux laptop with i7 and 16G ram. The most important part of the surveys for my project is the accuracy of the structures, tubing and columns, as I plan to add tags / labels to specific locations on each of these items in the generated models. Below is a link to an example from one of my test projects.
Any suggestions on how to improve the output results?
Should I break up the projects into smaller more focused / zoomed areas (Submodels), each with multiple Point of Interest flight plans at various radius and elevations?
What type of flight plan might work best, and is there a manual flight mode for DJI that takes photos at set distances from the previous point?
Should a camera calibration flight plan be incorporated in each projects flight plans when a 3D model is the desired result and how should it be different from the mapping flight plans at 20degree angles and camera looking forward 5 degrees?
What distance should photos be taken if I want to show the routing of 2 or 3" width tubing or bars accurately? I am seeing rough or jagged stitching of some of the smaller tubing and columns that I hope to improve upon.
