Rapid color verification system using digital imaging and curve comparison algorithm

摘要

A system is disclosed for monitoring paint color across regions of a vehicle, for identifying color mismatches, and for dynamically determining the acceptability of an identified mismatch. The system includes a vehicle image acquisition array digital cameras for digitally scanning selected regions of the vehicle and an image analyzer connected to the vehicle image acquisition system. The image analyzer is programmed with standard confidence color curves and includes software programmed with an analysis algorithm to convert an image of a scanned region into a standard image format. Individual color curves are extracted from the standard format to compare the extracted color curves against the standard confidence color curves to determine whether or not the extracted color curves fall within standard confidence color curves. The standard confidence color curves may be adjusted during color testing based upon accumulated extracted color curves.
