The Effects of Pattern and Color on the Visual Detection of Camouflaged Vehicles

摘要

Two camouflage experiments were conducted in which subjects searched for model armored personnel carriers placed singly on a terrain model. The effects of pattern contours, the number of colors used to paint the patterns, and the particular colors used on search times and detection probabilities were measured. Analyses of variance revealed no significant effects due to pattern contours or number of colors, while color per se was found to have a significant effect on search times. No significant differences were found between search times for an olive drab control target and pattern-painted targets. Search times and far visual acuity were found to be significantly correlated. It was concluded that pattern-painting does not affect target detection difficulty under the conditions tested in these experiments. (Author)
