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.
