| Abstract | The objective of this study to estimate the above-ground biomass of cassava using aerial imagery-derived UAV. The cassava plantation aerial imagery by UAV with a 20M pixel camera was acquired by flying at an altitude of 30 meters and 90 meters to compare the ability to estimate the fresh ABG biomass of cassava. The data processing of UAV images was carried out using modern computer vision algorithms for estimating the geometric parameters of cassava to calculate the fresh above-ground biomass of cassava from the allometric equation derived from the measurement of height (H) and the fresh biomass above the ground of the cassava from the cassava plantation. The results showed that the flying altitudes of 30 meters and 90 meters of the accuracy achievement had RMSE values of 0.65 and 0.98 respectively. This study can be used as a guideline for estimating the fresh above ground biomass of cassava plantation with UAV photogrammetry. |
