ADAM STERN, RESONON INC.Conventional vision systems often fail to sort items that have similar colors or appearances. In these cases, hyperspectral data combined with spatial pattern recognition algorithms can detect a wide range of materials, patterns, coatings, defects and contaminants. Hyperspectral vision systems generate data for quality control and also transmit information to robotic actuators, enabling automated picking and sorting of commodities. Hyperspectral imaging involves measuring high-resolution spectral data at every pixel in a 2D image. At each pixel in a hyperspectral image, the...Read full articleRelated content from Photonics MediaARTICLESIntelligent Lighting Brings Machine Vision to New HeightsMachine vision lighting technology must constantly evolve to meet increasing demands and keep pace with advancing imaging technologies.
