  • Patent number: 11094120
    Abstract: An inspection processing system includes a control unit connected to a photographing unit and an output unit. The control unit includes circuitry. The inspection processing system identifies a current position, displays a virtual image of a three-dimensional model of a structure corresponding to the current position. The virtual image is superimposed on a structure image obtained from the photographing unit. The inspection processing system further obtains an evaluation result of an evaluation item of an inspection subject using the structure image on which the displayed virtual image is superimposed, and records the evaluation result in an inspection information memory in association with the position of the inspection subject in the three-dimensional model.

  • Patent number: 10810734
    Abstract: Embodiments of the present invention generally relate to computer aided rebar measurement and inspection systems. In some embodiments, the system may include a data acquisition system configured to obtain fine-level rebar measurements, images or videos of rebar structures, a 3D point cloud model generation system configured to generate a 3D point cloud model representation of the rebar structure from information acquired by the data acquisition system, a rebar detection system configured to detect rebar within the 3D point cloud model generated or the rebar images or videos of the rebar structures, a rebar measurement system to measure features of the rebar and rebar structures detected by the rebar detection system, and a discrepancy detection system configured to compare the measured features of the rebar structures detected by the rebar detection system with a 3D Building Information Model (BIM) of the rebar structures, and determine any discrepancies between them.

  • Publication number: 20190033074
    Abstract: An inspection processing system identifies a current position, obtains an inspection result of an inspection subject of a structure on the current position, and records the inspection result in association with the position of the inspection subject in a three-dimensional model of the structure. The inspection processing system further identifies a user who views the three-dimensional model and a current position, and outputs, to an output unit, an inspection result in which the user is recorded in an inspection information memory as a related person of the inspection subject. The inspection result is attached on a virtual image according to a three-dimensional model corresponding to the current position.
