  • Publication number: 20200025553
    Abstract: [Problem] When inspecting whether each sleeve is in the correct position, to alleviate the burden on an operator and reduce the inspection time. [Solution] When an operator captures an image of a reference marker 3 or a sleeve marker 4 using a camera C, the image is sent to a sleeve marker position analyzing means 5 for the position of each sleeve marker 4, . . . to be analyzed. Then, a sleeve marker position assessing means 6 assesses whether the position of each sleeve marker 4, . . . is suitable, by superimposing the resulting analysis data and a BIM model stored in a BIM model storage means 2. Since it is sufficient for the operator to capture an image of the reference marker 3 or the sleeve marker 4 using the camera C, the burden on the operator can be alleviated, and the inspection time can also be reduced.
