Development of Criteria for Printing Color Reconnaissance Stereo Strip Photography for Interpretation Under Dynamic Viewing Conditions.

摘要

The purpose of the report is to determine,in searching for man-made targets in strip reconnaissance color photography,how the variables of camera lens convergence angle and film contrast contribute to performance and to develop a quantitative chromostereopsis test and determine the distribution of this phenomenon among observers. Sixty-three individuals were screened for their visual acuity, stereopsis, phorias at infinity and, 14inches (color vision only at 14inches). After brief training their target acquisition performance was measured using a Sonne SC-2near-real-time display of 1:2580scale reconnaissance chromatic imagery. The effects of convergence angles of 0, 10and 20degrees and of high,medium and low film contrasts were investigated. In preparing the stimuli a new target acquisition test was developed using Kodak SO-242high resolution color film. The flights were made by the USAF over Ft. Riley,Kansas.
