  • Patent number: 12141958
    Abstract: A first contact target position, a second contact target position, and a characteristic pattern for specifying a position and a posture of the workpiece are set in association with each other. First and second contact target positions for measurement are specified from a workpiece image newly generated during the execution of measurement such that a driving section is controlled to bring the touch probe into contact with the side surface of the workpiece with the specified first contact target position for measurement as a reference, and the driving section is controlled to bring the touch probe into contact with the upper surface of the workpiece with the specified second contact target position for measurement as a reference. Three-dimensional coordinates of a contact point are measured based on a contact signal output when the touch probe comes into contact with the workpiece.

  • Patent number: 11024049
    Abstract: The image measurement apparatus searches for a workpiece by performing a first stage operation. The image measurement apparatus generates an image in each imaging field-of-view while moving the stage according to a predetermined sequence, and determines whether or not the workpiece is included in each image. When the workpiece is found, the image measurement apparatus switches from the first stage operation to a second stage operation. The image measurement apparatus generates an image in one or more imaging field-of-views located in a direction in which the workpiece extends, among a plurality of imaging field-of-views located around the imaging field-of-view on the stage, in which the image has been obtained. The image measurement apparatus joins a plurality of images generated in the second stage operation to generate a joined image including the whole workpiece, and displays the joined image.

  • Publication number: 20100060903
    Abstract: A shape of a measurement object is measured based on an image obtained by applying light onto a stage having the measurement object mounted thereon and performing image formation of transmitted light or reflected light of the light on an imaging device. An image of the measurement object that is obtained by image formation on an imaging device is displayed within the range of the field of view, and feature quantity information is extracted based on the image of the measurement object. A determination is made as to whether feature quantity information approximately in agreement with the extracted feature quantity information is stored. If it is determined that the feature quantity information approximately in agreement with the extracted feature quantity information is stored, then the shape of the measurement object is measured based on information on measurement conditions stored in association with the feature quantity information.
