摘要： PROBLEM TO BE SOLVED: To provide a system for inspecting the inside of a conduit capable of accurately grasping the conditions of the internal wall surfaces of the conduit of sewerage etc. over its length even if flowing water is present in the conduit and retaining them for record. SOLUTION: In the system, inspections on the inside of the conduit T are performed by images by mounting an omnidirectional mirror 1 and a still camera 2 to a hull S floating in flowing water F in the conduit T. A laser pointer 6 is provided for irradiating at least three laser light spots to the internal wall surfaces of the conduit T. Then the attitude and position of the hull S are detected on the basis of the positional relation among laser light spot images in images acquired by imaging the laser light spots. On the basis of the results of detection, hemispherical images imaged by the still camera 2 are developed to perform correction when the hemispherical images are converted into rectangular planar images.

解决方案：在系统中，通过将全向镜1和静止照相机2安装在浮动在管道T中的流水F中的船体S上，通过图像执行导管T内部的检查。激光指示器6 提供用于将至少三个激光光点照射到导管T的内壁表面。然后，基于通过对激光成像获得的图像中的激光光点图像之间的位置关系来检测船体S的姿态和位置光点。基于检测结果，显影由静止照相机2成像的半球形图像，当半球形图像被转换为矩形平面图像时进行校正。版权所有（C）2005，JPO＆NCIPI
