A potentially economical system designed for the wide-spreading photogrammetric applications in a non-photogrammetric environment has been investigated and developed. This system makes use of a microcomputer and an enlarger-digitizer for image coordinate measurements. The authors evaluated the reliability and accuracy of the enlarger digitizer approach and compared it against comparator-digitized image coordinates. The evaluation examined the terms of the individual transformation as well as the performance within a bundle block adjustment. -Authors
