The Potential of Widespread UAV Cameras in the Identification of Conifers and the Delineation of Their Crowns

Popis výsledku v původním jazyce

With the ever improving advances in computer vision and Earth observation capabilities, Unmanned Aerial Vehicles (UAVs) allow extensive forest inventory and the description of stand structure indirectly. We performed several flights with different UAVs and popular sensors over two sites with coniferous forests of various ages and flight levels using the custom settings preset by solution suppliers. The data were processed using image matching techniques, yielding digital surface models, which were further analyzed using the lidR package in R. We conclude that widely used low cost RGB cameras yield very satisfactory results for the description of the structural forest information at a 150 m flight altitude. When (multi)spectral information is needed, we recommend reducing the flight level to 100 m in order to acquire sufficient structural forest information. The study contributes to the current knowledge by directly comparing widely used consumer grade UAV cameras and providing a clear elementary work
