Photogrammetry For Roof inspections, Solar Panels, and Hard-To-Reach Assets: A Technical Approach
Photogrammetry for roofs, solar panels, and complex vertical structures requires far more precision than standard terrain mapping. This post from explores why traditional workflows fall short and how operators can use tools such as terrain-following, custom camera profiles, circlegrammetry, and automated vertical scanning to achieve consistent results. Packed with real-world examples and scientific validation, it provides a practical technical guide to improving model accuracy, mission repeatability, and inspection efficiency across challenging commercial environments.Capturing quality photogrammetry data from vertical and elevated structures remains one of the trickier challenges in commercial drone operations. Traditional surveying workflows fail here. Kristaps Brass, Product Owner at UgCS, has spent years working with operators who tackle these missions daily. Solar farms, building facades, communication towers, dam inspections. The pattern is consistent: manual flying burns time and money, and processed models show gaps where critical details should be. This article covers what actually works, based on field-tested methods and real operator feedback.
