1. A method for verifying drug portions, comprising:
receiving, by a first verification device and a second verification device, characteristic key data for a drug, the characteristic key data based on images for the drug captured by a calibrated measuring camera disposed over a support surface upon which the drug is arranged;
receiving a package including a drug portion of the drug, the package including an identifier for the drug portion included in the package;
receiving, by the first verification device and the second verification device, a digital image of the package from a calibrated verification camera arranged above the package and that is separate from the calibrated measuring camera;
determining, by each of the first verification device and the second verification device, individual key data for the drug portion included in the package based at least on a known calibration parameter of the calibrated verification camera and the digital image of the package including the drug portion;
comparing, by each of the first verification device and the second verification device, the individual key data with the characteristic key data for the drug; and
verifying or rejecting, by each of the first verification device and the second verification device, the package including the drug portion corresponding to the drug based on a result of the comparing.
