  • Patent number: 11037337
    Abstract: When generating a measurement plan for measuring X-ray CT that performs X-ray irradiation while rotating a test object, and in doing so acquires projection image data, reconstructs volume data from the projection image data, and measures a targeted measurement location in the volume data, the present invention calculates required measurement accuracy and a measurement field of view range based on tolerance information included in CAD data of the test object and a measurement location on the test object defined by a measurement operator ahead of time, and automatically generates, from this information, an optimized measurement plan that minimizes the number of measurements.

  • Patent number: 9390324
    Abstract: A control unit shifts an imaging unit relatively with respect to a stage to take an image of a measuring object at a plurality of places by the imaging unit and thereby obtain a plurality of images, and generates a composite image of the measuring object having a range which is wider than an imaging range of the imaging unit by combining the plurality of images. The control unit shifts the imaging unit relatively with respect to the stage such that parts of images adjacent to one another obtained by the imaging unit overlap, and performs an image matching processing that performs image matching of an overlapped portion of the adjacent images. The control unit generates the composite image of the measuring object by joining the adjacent images at a position where the image matching is performed in the image matching processing.

  • Patent number: 9207156
    Abstract: A hardness tester that measures a size of an indent to determine the hardness of a sample. The hardness tester includes an imaging unit, a display unit, a pointing device and a position adjustment unit. The imaging unit takes an image of a surface of the sample. The display unit displays a surface image of the sample and a cursor. The pointing device receives a first instruction instructing a movement of the surface image of the sample appearing on the display unit through a movement of the cursor, and a second instruction instructing a change in a height of the sample stage through a movement of the cursor. The position adjustment unit moves the sample stage in a horizontal direction and in a vertical direction.

  • Patent number: 9013574
    Abstract: A machine vision system program editing environment including synchronized selection and/or identification of related features in a plurality of different user interface windows is provided. In particular, one of the windows is an editing window where a part program representation is displayed for editing by a user. In one embodiment, a user may select data or another feature of interest in a window that is not the editing window (e.g., a results window, or graphical workpiece inspection feature display window) and the associated part program instruction representation is automatically highlighted and/or selected in the editing window. Conversely, a part program instruction representation may be selected by a user in the editing window and the associated results or feature in another window is automatically highlighted and/or selected. User interface navigation, rapid program quality assessment, and overall part program creation and editing efficiency are significantly enhanced in such an editing environment.

  • Patent number: 8578284
    Abstract: A hardness tester includes a monitor capable of displaying a main screen and an assistant screen; a first test location setter setting an indentation formation location on a test specimen for an initial test; and a second test location setter setting an indentation formation location on the test specimen for a retest. The second test location setter judges whether a new indentation formation location is suitable for a test based on a surface image of the test specimen and a setting condition obtained during the initial test, and, in a case where it is judged that the new indentation formation location is unsuitable for a test, sets again a coordinate point different from the coordinate point of the new indentation formation location as another new indentation formation location.

  • Patent number: 8566735
    Abstract: A hardness tester includes a monitor capable of displaying a main screen and assistant screen. A first test location setter sets a coordinate point of an indentation formation location, and stores a setting condition of the set coordinate point and the surface image of a first test specimen. A second test location setter displays the surface image of the first test specimen in the assistant screen when a surface image of a second test specimen is displayed on the main screen, and, when a reference coordinate is set on the surface image of the second test specimen, determines a coordinate point of an indentation formation location based on the set reference coordinate and the setting condition of the coordinate point stored by the first test location setter.

  • Patent number: 7454053
    Abstract: Methods and systems for automatically recovering a failed video inspection tool in a precision machine vision inspection system are described. A set of recovery instructions may be associated or merged with a video tool to allow the tool to automatically recover and proceed to provide an inspection result after an initial failure. The recovery instructions include operations that evaluate and modify feature inspection parameters that govern acquiring an image of a workpiece feature and inspecting the feature. The set of instructions may include an initial phase of recovery that adjusts image acquisition parameters. If adjusting image acquisition parameters does not result in proper tool operation, additional feature inspection parameters, such as the tool position, may be adjusted. The order in which the multiple feature inspection parameters and their related characteristics are considered may be predefined so as to most efficiently complete the automatic tool recovery process.
