  • Patent number: 11869219
    Abstract: An inspection support system for erroneous attachment includes an imaging device and an erroneous attachment detector. The imaging device is configured to capture an image that represents a state in which multiple components are attached to each other. The erroneous attachment detector is configured to convert a color space of the image into an HSV color space, create a comparative image on the basis of hue and saturation in the HSV color space, determine whether the multiple components are each a correct component and whether the multiple components are attached in a correct manner by comparing the comparative image with a correct image that is based on the hue and the saturation, and detect the erroneous attachment of at least one of the multiple components, in a case where the at least one of the multiple components is not the correct component and/or is not attached in the correct manner.

  • Publication number: 20230260104
    Abstract: An inspection apparatus is configured to inspect an inspection target including an attachment body and a specific part attached to the attachment body. A surface of the attachment body and a surface of the specific part are painted with a same color material. The inspection apparatus includes a storage device, an imaging device, and an image processing device. The storage device is configured to store in advance a reference image in which the attachment body and the specific part are captured in a state in which the specific part is correctly attached to the attachment body. The imaging device is configured to capture an inspection image of the inspection target. The image processing device is configured to determine incorrect attachment of the specific part in the inspection target based on the inspection image captured by the imaging device and the reference image stored in the storage device.

  • Patent number: 11610300
    Abstract: A determination device includes a computer. The computer is configured to compare an image of a component that is captured and a correct image that is associated with an operation procedure manual and in which the component is captured. The computer is configured to determine whether a component shape in the image of the component and a component shape in the correct image agree. If the two component shapes do not agree, the computer is configured to determine that the component and the operation procedure manual do not match.

  • Patent number: 11335016
    Abstract: An object checking device includes an area specifying unit, an image generator, and a difference specifying unit. The area specifying unit is configured to, based on a feature part extracted from captured image data obtained by capturing an object, specify an area corresponding to the captured image data in 3D model data of the object. The image generator is configured to generate image data of the specified area from the 3D model data. The difference specifying unit is configured to specify a part in which there is a difference between the captured image data and the image data.
