Claim One:
1. A method for generating accurate, high quality images comprising the steps of: a) acquiring a first raw scan of a portion of a target object across a scan line in a scan zone with a first camera and simultaneously acquiring a second raw scan of the same portion of the target object across the scan line in the scan zone with a second camera, the second camera being separated from the first camera in a camera zone such that the first and second camera have substantially different perspectives of the same portion of the target object; b) converting the first raw scan from analog to digital format resulting in first raw image data and converting the second raw scan from analog to digital format resulting in second raw image data; c) processing the first raw image data with a first set of flattening coefficients derived from measurements of variations in illumination and in first camera response across the scan line to a uniform diffusely reflecting target in the scan zone, resulting in first flattened image data from the target object, and processing the second raw image data with a second set of flattening coefficients derived from measurements of variations in illumination and in second camera response across the scan line to the uniform diffusely reflecting target in the scan zone, resulting in second flattened image data from the target object; d) compensating for parallax in first flattened image data with a first set of calculations, resulting in first orthographic image data; and compensating for parallax in second flattened image data with a second set of calculations, resulting in second orthographic image data; e) comparing first orthographic image data corresponding to a coordinate location that is a prior known geometric profile location on the target object with second orthographic image data corresponding to the coordinate location; f) selecting a pixel intensity value, for use as enhanced image data representing the coordinate location on the target object, from one of: i) the first orthographic image data corresponding to the coordinate location ii) the second orthographic image data corresponding to the coordinate location; iii) a result of a formula using a combination of the first and second orthographic data corresponding to the coordinate location.
