Recently photographic survey using small UAV (Unmanned Aerial Vehicle) has attracted attention. The SfM (Structure from Motion) method is a powerful tool to create a 3D model from multiple 2D images. In this study, the plant height of an energy crop erianthus was estimated by UAV-SfM method. The estimated height was lower than the measured height because the top of the leaf was not matched among images and the 3D model was not constructed. The difference between the estimated and the measured height was less than 0.5m and the correlation between the estimated and the measured height was high, so UAV-SfM method is useful for the estimation of the plant height of energy crops.
