Patent number: 10977825Abstract: [Problem] To enable three-dimensional measurement with good precision. [Solution] When three-dimensional measurement is to be performed with good precision using SLAM or the like, images of marks M1, M2, M3, M4 must be captured from various directions by a single-lens camera. In the present invention, directions of imaging by a camera are displayed as sectors C1, C2, C3, C4. For example, it is understood that whereas sectors C1 and C4 have a large central angle and imaging therein is performed from a wide range of directions, sectors C2 and C3 have a small central angle and imaging therein is performed from a narrow range of directions. A photographer seeing such a display can perform additional imaging, and images can therefore be obtained from a wide range of directions, and three-dimensional measurement can be performed with good precision.Type: GrantFiled: January 30, 2018Date of Patent: April 13, 2021Assignees: SUMITOMO MITSUI CONSTRUCTION CO., LTD., KYUSHU UNIVERSITY, NATIONAL UNIVERSITY CORPORATIONInventors: Kentaro Tokura, Naoki Nagamoto, Takao Kakehashi, Motohiro Ikehara, Hideaki Uchiyama

Patent number: 10816320Abstract: [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.Type: GrantFiled: October 4, 2017Date of Patent: October 27, 2020Assignee: SUMITOMO MITSUI CONSTRUCTION CO., LTD.Inventors: Kentaro Tokura, Naoki Nagamoto, Takao Kakehashi, Motohiro Ikehara, Hideaki Uchiyama
