  • Publication number: 20240112321
    Abstract: To suppress an error between measurements when a plurality of workpieces having the same shape are measured. A three-dimensional shape data generation apparatus includes: a storage unit that stores a plurality of measurement files in which each of measurement conditions of a workpiece and each of alignment images are associated with each other; a display control unit that causes a display unit to display a live image of the workpiece and an alignment image associated with one measurement file from among the plurality of measurement files stored in the storage unit; a reception unit that receives a measurement start instruction of the workpiece; and a measurement control unit that controls a structured illumination unit and an imaging unit based on the measurement condition associated with the one measurement file in response to the measurement start instruction.

  • Patent number: 10746539
    Abstract: A shape measuring device includes an optical-axis-direction driving section configured to minutely relatively displace a stage in an optical axis direction of a light receiving section with respect to a light projecting section and the light receiving section such that a phase of a projection pattern on the stage is shifted at a minute pitch finer than width of the phase of the projection pattern projected on the stage, the minute pitch being defined by controlling light projecting elements of a pattern generating section.

  • Patent number: 9959451
    Abstract: Provided is an image inspection device, an image inspection method and an image inspection program which are capable of easily and accurately inspecting a shape of an inspection target. In a setting mode, positioning image data of a setting target placed on a stage is registered. In an inspection mode, a positioning image is displayed on a display part based on the positioning image data. An image for positioning of the inspection target placed on the stage is displayed in the display part. Thereafter, image data for alignment of the inspection target is acquired, and then aligned to image data for alignment of the setting target. A size in a height direction of a measurement target place of the inspection target is measured based on the aligned height image data, to determine Pass/Fail of the inspection target. The determined determination result is displayed on the display unit.
