Ministry of Land, Infrastructure, Transport and Tourism Catalog Listed Technology | Supporting Bridge Scour Inspection with Underwater Drones

Technology for supporting scour inspection of bridges using underwater drones.

Are you having trouble with "confirming underwater parts" or "understanding scouring conditions" during bridge inspections? This document introduces the bridge scouring inspection support technology using underwater drones, as listed in the Ministry of Land, Infrastructure, Transport and Tourism's inspection support technology performance catalog. In addition to recording the appearance of underwater structures through camera footage, it supports the measurement of riverbed shapes around bridge pier foundations, the presence or absence of scouring, water depth, dimensions, and more using 2D imaging sonar. This allows for safe investigations without the need for divers, leading to organized records through photos, videos, and numerical data.
