Color analysis for measurement, presence/absence, and identification

Color tools

Cognex offers advanced color tools for applications including part sortation, color recognition and matching, assembly verification, and inspection. These tools include:
  • SearchMax: Finds colored patterns allowing translation, rotation, scale, and skew
  • Color Extractor and Segmentation: Provides simple color definition for complex color scenes, and high-speed color extraction for food and packaging applications
  • Color Match: Enables high-speed identification and sorting of colored parts 

Matching/Presence/Absence

Color analysis can be used for quality inspection in manufacturing applications that include presence/absence detection based on the pixel count of a reference color model with which the object is associated. Cognex color tools help ensure an accurate color match between components used in the same product while interpreting subtle color differences, such as between shades in the same color family.

Identification

Color analysis can also be used for quality inspection in manufacturing applications that include part identification where the colors of the part are analyzed. Cognex technology extracts a pre-trained color, pixel by pixel, for processing with greyscale vision tools. Powerful color extraction tools can extract a combination of colors at the same time.
