MANHOLE COVER INFORMATION MANAGEMENT SYSTEM AND MANHOLE COVER INFORMATION MANAGEMENT METHOD
To provide a manhole cover information management system and a manhole cover information management method by which a measurement result of a manhole cover can be more easily and appropriately managed.SOLUTION: A manhole cover information management system 1 includes: a road surface measurement unit 110 that outputs road surface measurement data by an optical cutting method including a height at each point of a road surface and laser beam reflection intensity; a vehicle measurement unit 120 that outputs vehicle measurement data including a geographic position and attitude of a vehicle; position specifying means that specifies a geographic three-dimensional position of each point; area extraction means that extracts a manhole cover area; information generation means that generates unevenness information within the manhole cover area; and memory control means that stores the unevenness information along with the measurement date and time and the geographic three-dimensional position.SELECTED DRAWING: Figure 2
【課題】マンホール蓋の計測結果をより容易かつ適切に管理可能なマンホール蓋情報管理システム及びマンホール蓋情報管理方法を提供する。【解決手段】マンホール蓋情報管理システム１は、道路面の各地点の高さ及びレーザ光反射強度を含む光切断法による路面計測データを出力する路面計測部１１０と、車両の地理的位置及び姿勢を含む車両計測データを出力する車両計測部１２０と、各地点の地理的三次元位置を特定する位置特定手段と、マンホール蓋領域を抽出する領域抽出手段と、マンホール蓋領域内の凹凸情報を生成する情報生成手段と、凹凸情報を計測日時及び地理的三次元位置とともに記憶する記憶制御手段とを備える。【選択図】図２
