Optoelectronic device for measurement of structural or object sizes

摘要

The device (10) has a light reception element (20) for converting received light into image data. An evaluation unit (22) determines dimensions in picture elements and converts the dimensions into absolute units of length with reference to a scaling factor. The evaluation unit reads out code information from the code regions and calculates the scaling factor during the calibration procedure from dimensions of a calibration code, where the code information includes size indication for the calibration code in the absolute units of length. An independent claim is also included for a method for calibrating an optoelectronic apparatus for measuring structural or object sizes.
