Abstract

A method of processing graphical image data representing optically scanned medication-related units may include receiving image data generated responsive to an application of light to a tray disposed a distance from an image acquisition component. The application of light may distinguish a background field from a plurality of the units disposed on the tray. The method may further include processing the image data to identify objects that correspond to respective ones of the units from the background field, counting the objects identified as corresponding to respective ones of the units, and generating an annotated image including at least a sequential number associated each one of the objects identified as corresponding to respective ones of the units.

Claims

1. A method of processing graphical image data representing optically scanned medication-related units comprising:

receiving image data generated responsive to an application of light to a tray disposed a distance from an image acquisition component, the application of light distinguishing a background field from a plurality of the units disposed on the tray;

processing the image data to identify objects that correspond to respective ones of the units from the background field;

counting the objects identified as corresponding to respective ones of the units; and

generating an annotated image including at least a sequential number associated each one of the objects identified as corresponding to respective ones of the units.

2. The method of claim 1, wherein generating the annotated image further comprises applying a respective sequential overlay number to each of the identified as corresponding to respective ones of the units.

3. The method of claim 2, wherein applying the respective sequential overlay number comprises applying sequential numbers to respective ones of the objects identified from one to a total number determined responsive to the counting.

4. The method of claim 1, wherein generating the annotated image further comprises generating one or more annotations descriptive of a prescription with which the annotated is associated.

5. The method of claim 1, wherein generating the annotated image further comprises generating one or more annotations descriptive of a medication with which the annotated is associated.

6. The method of claim 1, wherein generating the annotated image further comprises generating one or more annotations descriptive of a medication container with which the annotated is associated.

7. The method of claim 1, wherein generating the annotated image further comprises generating a time annotation, date annotation, target quantity, dispensed quantity or tray quantity of units responsive to the counting.

8. The method of claim 1, further comprising storing the annotated image in a memory to enable future retrieval of the annotated image.

9. A machine-vision based counting device for counting medication-related units comprising:

a tray disposed on a base unit to receive units;

an image acquisition component disposed a distance from the tray, the image acquisition component configured to generate image data responsive to an application of light to the tray, the application of light distinguishing a background field from the units disposed on the tray;

an image processor comprising processing circuitry configured to;

process the image data to identify objects that correspond to respective ones of the units from the background field;

count the objects identified as corresponding to respective ones of the units; and

generate an annotated image including at least a sequential number associated each one of the objects identified as corresponding to respective ones of the units.

10. The device of claim 9, wherein the processing circuitry is further configured to generate the annotated image by applying a respective sequential overlay number to each of the identified as corresponding to respective ones of the units.

11. The device of claim 10, wherein the processing circuitry is further configured to apply the respective sequential overlay number by applying sequential numbers to respective ones of the objects identified from one to a total number determined responsive to the counting.

12. The device of claim 9, wherein the processing circuitry is further configured to generate the annotated image by generating one or more annotations descriptive of a prescription with which the annotated is associated.

13. The device of claim 9, wherein the processing circuitry is further configured to generate the annotated image by generating one or more annotations descriptive of a medication with which the annotated is associated.

14. The device of claim 9, wherein the processing circuitry is further configured to generate the annotated image by generating one or more annotations descriptive of a medication container with which the annotated is associated.

15. The device of claim 9, wherein the processing circuitry is further configured to generate the annotated image by generating a time annotation, date annotation, target quantity, dispensed quantity or tray quantity of units responsive to the counting.

16. The device of claim 9, further comprising a memory configured to store the annotated image in a memory to enable future retrieval of the annotated image;

and a display configured to display the annotated image.

17. A computer program product comprising at least one computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions for:

receiving image data generated responsive to an application of light to a tray disposed a distance from an image acquisition component, the application of light distinguishing a background field from a plurality of the units disposed on the tray;

processing the image data to identify objects that correspond to respective ones of the units from the background field;

counting the objects identified as corresponding to respective ones of the units; and

generating an annotated image including at least a sequential number associated each one of the objects identified as corresponding to respective ones of the units.

18. The computer program product of claim 17, wherein program code instructions for generating the annotated image include instructions for applying a respective sequential overlay number to each of the identified as corresponding to respective ones of the units.

19. The computer program product of claim 17, wherein program code instructions for generating the annotated image include instructions for:

generating one or more annotations descriptive of a prescription with which the annotated is associated;

generating one or more annotations descriptive of a medication with which the annotated is associated;

generating one or more annotations descriptive of a medication container with which the annotated is associated;

or

generating a time annotation, date annotation, target quantity, dispensed quantity or tray quantity of units responsive to the counting.

20. The computer program product of claim 17, further comprising computer program code for storing the annotated image in a memory to enable future retrieval of the annotated image.
