Recent technical advances in drones make them increasingly relevant and important tools for forest measurements. However, information on how to optimally set flight parameters choose sensor resolution is lagging behind the developments. Our study aims address this gap, exploring effects of drone (altitude, image overlap, resolution) reconstruction successful 3D point extraction. This was conducted using video footage obtained from flights at several altitudes, sampled images varying...
