Wang et al. [89] proposed a completely new approach for monitoring ice velocity in rivers making use of UAVs and device eyesight technology. The strategy will involve employing UAVs to capture superior-resolution orthoimages through ice flood intervals, extracting characteristic points in drift ice visuals with the dimensions-invariant attribute transform algorithm https://marcoyiraj.blogchaat.com/30659489/agricultural-drone-survey-bd-no-further-a-mystery
