Abstract
Disclosed are image based counting systems and methods. Image based counting systems and methods employ one or more imaging devices (e.g., one or more color cameras) and one or more illumination devices (e.g., one or more illumination sources to provide variable and/or dynamic lighting). In some examples, the image based counting system provides illumination to a tray upon which one or more items (e.g., pills) are placed. The illuminated items are then imaged by the one or more imaging devices based on one or more imaging techniques or processes to determine and/or present information associated with one or more properties of the item.
Claims8
A system for processing a pharmaceutical order comprising:
- a platform to hold one or more pharmaceutical pills;
- a lighting source configured to illuminate the platform and pills having a plurality of illumination characteristics;
- one or more imaging devices to capture the illuminated platform and pills;
- a calibration device arranged on one or more surfaces of the system;
- and
- a controller configured to:
- receive images of the calibration device from the one or more imaging devices;
- control a focus the one or more imaging devices based on the images of the calibration device;
- receive images of the illuminated platform and pills from the one or more imaging devices;
- identify a characteristic of the plurality of illumination characteristics;
- compare the characteristic to a list of illumination characteristics that corresponds to a property of the pill;
- determine a property of the pill based on the comparison;
- and
- generate an alert associated with the property.
