Photogrammetry has been introduced as an alternative to direct measurements to obtain facial distances for a variety of anthropometric applications. We apply photogrammetry to assist in the screening of children for Fetal Alcohol Syndrome (FAS). We have developed a stereo-photogrammetric image acquisition platform to obtain digital photographs of 6 to 7 year-old children, and image processing algorithms to extract the eye features required for FAS screening from these photographs. Images are calibrated using the Direct Linear Transform. Eye features are extracted by examining peak and valley maps to locate the eyes and extract the iris contour, and applying a genetic algorithm to match cubic splines to eye contours. * Corresponding author. 1
