Development of Instrumental Techniques for Color Assessment of Camouflage Patterns

ProQuest LLC, Ph.D. Dissertation, North Carolina State University
Camouflage fabrics are produced on a large scale for use in the US military and other applications. One of the highest volume camouflage fabrics is known as the Universal Camouflage Pattern (UCP) which is produced for the US Department of Defense. At present, no standard measurement-based color quality control method exists for camouflage substrates. All assessments are performed visually under standard daylight simulation at a correlated color temperature of 7500K. Visual pass/fail decisions involve myriad factors that affect accuracy and repeatability. In the case of camouflage material, visual assessment decisions are far more complex than those of solid colors. The variability in the visual assessments is currently unknown for Universal Camouflage Pattern substrates. This can cause problems in color quality control in the supply chain and production of the finished fabric. Hence, a system is required that can accurately, repeatedly and rapidly predict pass or fail decisions objectively according to a defined tolerance, and this is the primary objective of this work. The research goals include: 1. Development of a spectrophotometric and a non-contact based standard instrumental method for assessment of Universal Camouflage Pattern; 2. Verification the performance of the instrumental methods against the visual pass/fail data. A calibrated digital camera system was developed using a calibrated light box for illumination of the samples. A key goal was to develop an integrated system that allows colorimetric measurement. Dedicated software was developed to control devices and obtain pass/fail ratings. The key criterion was the repeatability and accuracy of digital measurements such that they were well within the visual pass/fail tolerances of the camouflage substrates.
