METHOD AND SYSTEM FOR MATCHING A SURFACE COLOR |
摘要 |
The digital image is analyzed to determine the captured target color (12) an d the captured colors of the test card color fields (20). A correction model accounting for ambient lighting conditions and distortion due to image capturing device is computed from the captured and known colors of the test card color fields. The correction model is applied to the captured target color (60) and the estimated true target color is compared to a database of true product color (80) to determine a nearest matching.
