  • Patent number: 12333644
    Abstract: A processor causes a storage medium to store three-dimensional data of a subject in a storage step. The processor selects a reference image in a first selection step. The processor selects a selected image that is a two-dimensional image used for generating the three-dimensional data on the basis of the reference image in a second selection step. The processor estimates a second camera coordinate regarding the reference image on the basis of a first camera coordinate regarding the selected image in an estimation step. The processor displays an image of the subject on a display in a display step. The image of the subject visualizes at least one of the second camera coordinate and a set of three-dimensional coordinates of one or more points of the subject calculated on the basis of the second camera coordinate.

  • Patent number: 12316822
    Abstract: In a three-dimensional image display method, a processor acquires first three-dimensional data and second three-dimensional data of a subject from a recording medium. The processor converts a first three-dimensional coordinate system of the first three-dimensional data and a second three-dimensional coordinate system of the second three-dimensional data into a three-dimensional common coordinate system on the basis of structure information related to a geometric structure of the subject. The processor displays an image of the first three-dimensional data in the common coordinate system and an image of the second three-dimensional data in the common coordinate system on a display.

  • Publication number: 20250014173
    Abstract: A three-dimensional data generation method includes the following processing. A processor acquires two or more images of a component inside a turbine. The processor detects two or more correspondence regions that are the same regions in at least two images. The processor determines whether at least part of a region of each image is a change region or a non-change region. The processor generates three-dimensional data by using a correspondence region determined to be the change region without using a correspondence region determined to be the non-change region.

  • Patent number: 11650407
    Abstract: An imaging condition set in a first region of a three-dimensional model of a subject and an imaging condition set in a second region of the three-dimensional model are different from each other. A processor of an observation device determines whether or not the imaging condition that has been set in the first region or the second region including a position on the three-dimensional model is satisfied. The position is identified on the basis of a position of an imaging device and a posture of the imaging device. The processor displays observation information on a display on the basis of a result of determination. The observation information represents whether or not the first region or the second region including the position on the three-dimensional model has been observed.

  • Patent number: 11321861
    Abstract: In a measurement device, an image acquisition unit acquires a first image generated by imaging an object to be measured in a first imaging state and acquires one or more second images generated by imaging the object in one or more second imaging states. A specified point setting unit sets a specified point on the first image. A three-dimensional (3D) shape restoration unit restores a 3D shape of the object by using a plurality of images including the second image determined to include a point corresponding to the specified point. A reference dimension setting unit sets a reference dimension on the first image or the 3D shape. A measurement unit measures the object on the basis of the 3D shape, the specified point, and the reference dimension.

  • Patent number: 11120543
    Abstract: A measurement processing device includes an imaging unit, an image acquisition unit, a display unit, a measurement point display control unit, a corresponding-point calculation unit, a corresponding-point image generation unit, and a corresponding-point image display control unit. The measurement point display control unit causes a measurement point indicating a measurement position designated by a user to be displayed on a first image. The corresponding-point image generation unit generates a corresponding-point image that includes the corresponding point calculated by the corresponding-point calculation unit and a region in the vicinity of the corresponding point in the second image and is constituted of all or a part of the second image. The corresponding-point image display control unit causes the corresponding-point image to be displayed so that a straight line passing through the measurement point and the corresponding point is orthogonal to the parallax direction on a display screen.

  • Patent number: 11055865
    Abstract: A control unit recognizes a direction accepted by an operation unit in a case in which an image acquisition mode is set in an image acquisition device. An image acquisition condition in the image acquisition mode is defined by first information and second information. The first information represents a speed or a distance at which the imaging visual field is changed. The second information represents a timing at which images used for restoration of the three-dimensional shape are acquired. The control unit causes a visual field changing unit to change the imaging visual field at the speed in the recognized direction or change the imaging visual field by the distance in the recognized direction. The control unit acquires at least two images at the timings from an imaging unit.
