Abstract

A system and method for recognizing a medication are provided. The method includes the steps of presenting a medication to a medication identification apparatus, the medication identification apparatus adapted to visually image the presented medication and visually imaging the presented medication. A predetermined transformation may be applied to the visually imaged presented medication, the predetermined transformation adjusting one or more parameters of the visually imaged presented medication along one or more dimensions. Finally, the transformed visually imaged medication is compared to a medication library to determine a closest match therebetween.

Claims

1. A method for training a medication identification apparatus, comprising the steps of:

teaching a visual recognition system of a medication identification apparatus to recognize one or more medications;

presenting a new medication to the medication identification apparatus to be imaged thereby;

determining a transformation from one of the predetermined medications to the presented new medication along one or more dimensions; and

storing the determined transformation associated with the new medication.

2. The method of claim 1, further comprising the step of confirming that the one or more medications cover a desired spectrum of possible new medications.

3. The method of claim 1, further comprising the step of imaging multiple versions of a new medication to address variation therein.

4. The method of claim 1, further comprising the steps of:

determining one or more environmental factors that may affect the teaching of the visual recognition system to recognize each of the one or more medications; and

adjusting the parameters of the recognition of the one or more medications in accordance with the one or more determined environmental factors.

5. The method of claim 1, further comprising the steps of:

determining one or more environmental factors that may affect the imaging of the new medication by the medication identification apparatus; and

adjusting the parameters of the transformation in accordance with the determined one or more environmental factors.

6. The method of claim 5, further comprising the step of providing illumination from the medication training apparatus to overcome one or more determined environmental factors.

7. The method of claim 1, wherein the visual recognition system of the medication training apparatus is located at a remote location to the medication training apparatus.

8. The method of claim 1, wherein the step of presenting the new medication further comprises the step of performing one or more predetermined movements with the new medication as directed on a display of the medication identification apparatus.

9. The method of claim 1, wherein the determined transformation is stored along with the one of the predetermined medications.

10. The method of claim 1, wherein the determined transform is applied to the one of the predetermined medications and stored as a new medication.

11. The method of claim 1, wherein the one or more of the predetermined medications comprises the predetermined medication having a closest match with the new medication along the one or more dimensions.

12. A method for recognizing a medication, comprising the steps of:

presenting a medication to a medication identification apparatus, the medication identification apparatus adapted to visually image the presented medication;

visually imaging the presented medication;

comparing the visually imaged medication to a medication library to determine a closest match therebetween;

applying a predetermined transformation to the visually imaged presented medication in accordance with the determined closest match in the medication library, the predetermined transformation adjusting one or more parameters of the visually imaged presented medication along one or more dimensions; and

comparing the transformed visually imaged medication to the closest match in the medication library to confirm the identity of the visually imaged presented medication.

13. The method of claim 12, further comprising the steps of:

determining one or more environmental factors that may affect the imaging of the presented medication by the medication identification apparatus; and

adjusting the parameters of the transformation in accordance with the determined one or more environmental factors.

14. The method of claim 13, further comprising the step of employing a light associated with the medication identification apparatus if it is determined that such use may improve the determined one or more environmental factors.

15. The method of claim 12, further comprising the step of presenting one or more visual prompts to a user to perform one or more predetermined motions when presenting the medication to the medication identification apparatus.

16. The method of claim 15, further comprising the step of providing immediate visual feedback to the user if it is determined that the user has not properly followed the one or more visual prompts, and therefore has not properly presented the medication.

17. The method of claim 12, further comprising employing the imaged presented medication data to further adjust the predetermined transformation.

18. A system for identifying medication, comprising:

a medication library stored to a non-transient computer readable storage medium, the medication library being formed by;

teaching a visual recognition system of a medication identification apparatus to recognize each of the one or more medications;

storing visual recognition data for each of the one or more medications to the medication library;

presenting one or more new medication to the medication identification apparatus to be imaged thereby;

determining a transformation from one of the stored medications to each of the one or more presented new medications along one or more dimensions; and

storing the determined transformations associated with the new medication to the medication library; and

a medication identification apparatus adapted to visually image a medication presented thereto;

apply a predetermined transformation from the medication library to the visually imaged presented medication, the predetermined transformation adjusting one or more parameters of the visually imaged presented medication along one or more dimensions; and

comparing the transformed visually imaged medication to one or more of the predetermined medications stored in the medication library to determine a closest match therebetween.

19. The system of claim 18, wherein the medication identification apparatus further determines one or more environmental factors that may affect the imaging of the presented medication by the medication identification apparatus, and adjusts parameters of the transformation in accordance with the determined one or more environmental factors.

20. The system of claim 18, wherein the medication identification apparatus comprises a mobile computing device.
