Abstract:
1. A pattern measuring apparatus comprising: a measurement region setting unit that sets a measurement region in image data obtained by imaging a sample, a pattern to be measured being formed on a sample, and the image data including data corresponding to the pattern; a matching unit that performs pattern matching between the image data and previously stored pattern data; a “region not to be measured” setting unit that sets, as a region to be excluded from subjects to be measured, a predetermined region in the image data aligned by the matching unit; and a pattern measurement unit that extracts pattern image data included in the measurement region and obtains a dimension of the pattern formed on the sample based on the extracted pattern image data, wherein: the pattern measurement unit carries out pattern measurement as to the extracted pattern image data included in the measured region, with excluding image data included in a region where the measurement region and the predetermined region overlap with each other, and at least one of the above units is implemented by a processor.
