INSPECTION SYSTEM FOR INSIDE OF PIPELINE FACILITY
To provide an inspection system for the inside of a pipeline facility capable of obtaining a travel distance of a moving body from image data captured for inspecting the inside of a pipeline facility extending in a longer direction without the necessity of a cable or a travel distance sensor in a horizontal direction.SOLUTION: An inspection system for the inside of a pipeline facility comprises a moving body on which an imaging device is mounted. An image processing device is provided with an area extraction unit 14 for obtaining first image data 12 and second image data 10 captured at different two points in the longer direction in the pipeline facility and extracting a specific area from the first image data 12 or the second image data 10, a search unit 20 for searching for an area corresponding to the extracted specific area, in the other image data, a position difference calculation unit 26 for determining a deviation of a position between the specific areas, a right/left in-plane distance calculation unit 32 for calculating distance from an inner face of the pipeline facility to the imaging device on the basis of the deviation of the position, and a travel distance calculation unit 38 for calculating distance between two points on the basis of a view angle and the distance from the inner face to the imaging device.SELECTED DRAWING: Figure 3
【課題】ケーブル或いは水平方向の移動距離センサを要することなく、長手方向に延在する管路施設内を検査のために撮像される画像データから移動体の移動距離を取得し得る管路施設内検査システムを提供する。【解決手段】管路施設内検査システムは、撮像装置を搭載する移動体を備え、画像処理装置は、管路施設内において長手方向に異なる２地点にて撮像された第１の画像データ１２及び第２の画像データ１０を取得し、第１の画像データ１２又は第２の画像データ１０から特定領域を抽出する領域抽出部１４、抽出された特定領域が他方の画像データ内で対応する領域を探索する探索部２０と、特定領域間の位置の偏差を求める位置差分算出部２６、位置の偏差に基づき管路施設の内面から撮像装置までの距離を求める左右面内距離算出部３２、及び特定領域の視野角と内面から撮像装置までの距離に基づき２地点の間の距離を求める移動距離算出部３８を有する。【選択図】図３
