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.

Abstract: An image measuring apparatus includes an image capturer capturing an image of a measured object and outputting image data; a memory storing a plurality of first measurement data including the image data; a transmitter transmitting the first measurement data stored in the memory; a controller controlling the image capturer, the memory, and the transmitter; and a position control system controlling a position of the image capturer and outputting second measurement data including focus position data of the image capturer. During position control, the controller capturers an image at a predetermined interval and stores in the memory the first measurement data and the second measurement data so as to be associated with each other. The transmitter transmits the first measurement data stored in the memory depending on a communication status.

Abstract: A current value corresponding to a relationship between an illumination intensity instruction value and illumination intensity is calculated based on a previously obtained relationship between a current flowing through a light emitting device and the illumination intensity. A calibration table including the illumination intensity instruction value, the current value, and the illumination intensity is created. A required illumination intensity is calculated during measurement. An illumination intensity instruction value corresponding to the required illumination intensity is calculated. The illumination intensity instruction value is set using the calibration table.
