Error proofing and quality control for color match detection
Achieving accurate color match detection of bumpers and fenders in automotive paint shops presents several challenges. The implementation of standardized lighting conditions, rigorous quality control measures, and regular calibration can further improve the accuracy and consistency of color matching in automotive paint shops.
Challenge
Inconsistent lighting, varied surfaces and human error
One of the primary challenges is dealing with color variation due to variations in paint batches, production conditions and surface textures. Inconsistent lighting conditions can also affect color perception and make it difficult to achieve consistent color matches. Surface imperfections on bumpers and fenders, such as scratches or dents, can further complicate the color detection and matching process. Additionally, human error and subjective color perception can introduce inconsistencies in color matching.
Solution
Real-color processing for high-speed, human-level matching
Omron’s FH Series vision system is a compact yet powerful solution for advanced quality inspection, identification and positioning applications. With top-of-the-line sensing and processing capabilities, the vision system is designed to maximize production line performance and flexibility by matching and exceeding the sensitivity of human vision. Real-color processing is an image processing technology that performs high-speed processing of full-color images with a total of 16.7 million colors (256 tones per RGB channel). This means that image processing can be performed with the same color information that is visible to the human eye, and stable measurements can be performed under lighting that closely resembles natural light.
