Wang et al. [89] proposed a brand new strategy for monitoring ice velocity in rivers utilizing UAVs and machine vision technology. The method requires employing UAVs to seize superior-resolution orthoimages during ice flood periods, extracting aspect details in drift ice images with the scale-invariant feature change algorithm and monitoring the https://tituslzlvf.qodsblog.com/30644661/a-secret-weapon-for-drone-land-survey-bangladesh
