Project Overview

• Objective

– Instrumentation and standardization for CAMO shade/color inspection

• Technical Approach

– Hardware design, digital imaging system– Software/algorithm/codes development– St ti ti l l i b t i l d i t t l th d Statistical analysis between visual and instrumental methods

– Large numbers of samples with visual inspection results  “calibrate” instrum

– Standards (criteria and tolerance) based on current DoD experts’ visual inspe

• Pay out

– Eliminating the human subjectivity– Minimizing inspection discrepancy among government and industry– Reducing government and manufacturers Reducing government and manufacturers’ risks on cost and schedule risks on cost and schedule– Significantly improving the color/shade consistency for better protection– Dramatically reducing end item cost

Recommendations and Requests

1. Standardize sample size - at least one repeat unit 2. Standardize reference 4 corner points for test sample inspection area3. Procedures to transfer samples from all First Article and all Lot inspection TS to NRSDEC for their for their "inspection inspection“4. Procedures to transfer inspection results from DLA to NCSU5. Procedures to transfer samples and inspection results from Procedures to transfer samples and inspection results from NRSDEC to N

to N

6. Need support from government labs, academia and industry
