Abstract: A non-contact surface-shape measuring method uses a white light interferometer optical head that divides, through a beam splitter, light emitted from a white light source into reference light for a reference mirror and measurement light for a measured object surface; obtains an image having interference fringes generated from an optical path difference of light reflecting from the reference mirror and light reflecting from the measured object surface; and is displaced for scanning in a vertical direction with respect to the measured object surface in order to obtain the image having interference fringes. While the white light interferometer optical head is displaced in a scanning direction, a position of the optical head in the scanning direction is detected, and the image having interference fringes is obtained at predetermined spatial intervals in the scanning direction.

Abstract: An image measuring apparatus is configured such that an image of a measured object placed on a stage is captured by a camera, the captured image is displayed on a captured image display screen, and determination results based on results of a measurement are displayed in an overview list separately from the captured image of the measured object. The image measuring apparatus includes a selector selecting measurement results that include determination results on the list; and an emphasis displayer providing an emphasis display on the captured image display screen for a measurement position corresponding to the selected measurement results.

Abstract: An image measuring method performed with an image measuring device measuring a dimension of a measured object from an image of the measured object captured by an image capturer. The method executes a standard reference object measurement measuring a dimension of the standard reference object with the image measuring device; a standard reference dimension input inputting a dimension of the standard reference object specified by a device other than the image measuring device; a preset value calculation calculating a preset value from the dimension of the measured standard reference object and from a dimension of the standard reference object measured by a predetermined measurement tool; a measurement measuring a dimension of a measured object other than the standard reference object using the image measuring device; and a correction correcting the dimension of the measured object other than the standard reference object measured by the image measuring device.

Abstract: A distance in a scanning direction between a first set of edges which face each other and exhibit an opposite change between light and dark is measured by an image measuring machine, and a bias correction value is calculated based on a difference between a measured value and a true value. Using the bias correction value, detection point correction values, which are correction values in various directions of edge detection points detected by a scan of a measured object using the image measuring machine, are calculated; a correction amount used in correction of the edge detection points is specified based on the detection point correction value in each direction; and the edge detection points are corrected using the correction amount.
