Abstract:
1. An automatically self-calibrating magnifying measurement system, comprising: a) a calibration standard having a reference object with at least two landmark features of differing scales identifiable by pattern recognition at a plurality of magnifications, dimensions of which have been verified and digitally archived in association with a unique identification code for the calibration standard, the landmark features each being associated with a distinctive marking that can be read by pattern recognition to identify the different landmark features, the calibration standard also having a machine readable identification code marker configured to appear in a magnified digital image of the reference object, the identification code marker corresponding to the unique identification code for the calibration standard; b) a stage to position the calibration standard, and alternatively to position a sample; c) image acquiring means for acquiring magnified digital images of the reference object, and alternatively for acquiring a magnified digital image of the sample; d) a data storage module for storing information including the unique identification code for the calibration standard and the associated verified dimensions of the landmark features of the reference object; e) a control module configured to control the stage and the image acquiring means to obtain digital images of the reference object of the calibration standard at a plurality of magnifications, and alternatively to obtain a digital image of the sample; and f) a data processing module configured to:
