In this study, the vegetation status of Erianthus using unmanned-aerial-vehicle (UAV) photogram-metry integrated with structure from motion (SfM) was investigated. When estimating the height of Erianthus, the values estimated using the UAV-SfM method were slightly smaller than the measured value because of the difficulty in matching leaf tips in aerial images. However, the height could be estimated with a determination coefficient of 0.95 or more at altitudes of 50 m, 50 m + diagonal, and 100 m. It was revealed that the UAV-SfM method is suitable for estimating the Erianthus height, and aerial shooting at an altitude of 100 m is sufficiently accurate.
