Paper Abstract

As a kind of photogrammetric platform unmanned aerial vehicles (UAVs) usually employ amateur digital cameras, the photogrammetric data availability depend on the integrated sensors calibration result and the flight performance, which are great limitations to the UAV systems used in aerial photogrammetry. In this work, a specific workflow for the UAV system calibration in survey field is introduced, first a calibration field built in the survey region by using artificial targets as ground control points, furthermore, a specific flight planning is developed, then we take a fix-wing UAV to implement the survey work. The results for the bundle adjustment are less than 0.5m. which is better than estimated the camera interior orientation parameters(IOP) in the lab. Also the study described which source of errors influenced the UAV photogrammetry and bring forward improvement advice.
