Accuracy verification of photogrammetry by the combination of an UAV with RTK function and a mobile GNSS station
survey, nadiral and oblique air photographs were taken by an UAV with RTK function. Three-dimensional RMSE of the nadiral and oblique photographing were 7.514.0, 4.26.7, 2.43.6 cm and 6.19.5, 2.03.3, 2.75.5 cm, with 0, 1 and 5 GCPs respectively. It was considered that oblique photographing without any GCPs was suitable for forest photogrammetry with both cost and accuracy perspective, because both horizontal and vertical RMSE were less than 10 cm. Furthermore, it was considered that oblique photographing with one GCP is also good for better accuracy.
