Abstract: A cannabis bud sorting, picking and filling system includes a computer vision system operable to view and estimate the weight of a plurality of buds on a bud picking tray and to direct a bud picker robot to pick a plurality of buds from the bud picking tray and deposit the picked buds in an amount to load a container to its predetermined loaded target weight. A computer vision system acquires a digital image of product items having a product type, identifying each product item in the image, determining a pixel-based area for each identified product item, predicting a weight of each identified product item based on a size thereof, the determined pixel-based area and a predetermined density based on the product type, grouping, based on the predicted weights, the identified product items into groups satisfying the target weight, and automatedly picking and placing each group into a container.
