Wang et al. [89] proposed a fresh approach for monitoring ice velocity in rivers employing UAVs and machine vision technology. The tactic will involve working with UAVs to capture higher-resolution orthoimages through ice flood intervals, extracting attribute factors in drift ice images with the dimensions-invariant aspect renovate algorithm and tracking https://judahktdnw.ltfblog.com/29859413/detailed-notes-on-construction-drone-survey-bangladesh
