A Quest For The Best – Looking Fruits And Vegetables, That Is!
Sizing and sorting fruit
The images are then processed using the Matrox Imaging Library (MIL) toolkit. Binarization and blob analysis are used to separate the fruit from its background and to obtain dimensions like Feret diameters and elongation, for example. The HLS (Hue, Luminosity, Saturation) color space conversion and statistical functions are used for color processing. And convolutions and custom-designed algorithms recognize stems and cores, and reject fruit with defects on the skin like black spots or russet.
The system's intuitive user interface, which includes a 3D display, lets operators adjust quality and sorting parameters in real-time. These parameters can be stored for future use. GLOBALSCAN® gives production managers the ability to analyze the data gathered from the vision system and generate statistics by producer, by orchard or field, by species, or by variety of fruit. Reports provide metrics on the batch of fruit that is being processed including size, weight, diameter, color, and quality.
