Abstract

Devices and systems for image-based analysis of test media are disclosed herein. An example device includes four side panels connected together so as to form a tubular rectangle, a floor panel that covers an opening of the tubular rectangle, the floor panel having a raised test bed that receives a test medium, a top panel that having an optical lens that aligns with the raised test bed when the top panel covers another opening of the tubular rectangle. The optical lens is aligned with an aperture that extends through the top panel. The four side panels, the floor panel, and the top panel forming an optic chamber when joined together. The device also includes a light source that illuminates inside the device.

Claims

1. A device, comprising:

a tubular rectangle;

a floor panel that covers an opening of the tubular rectangle, the floor panel comprising a test bed that receives a test medium;

a top panel comprising an optical lens;

the tubular rectangle and the floor panel forming an optic chamber when joined together;

an illumination volume of the optic chamber illuminated by a light source; and

brackets disposed on each corner of the tubular rectangle, the brackets allowing for selective increasing or selective decreasing of the illumination volume based on placement of the floor panel in contact with a portion of the brackets.

2. The device of claim 1, wherein the floor panel further comprises a QR/bar code.

3. The device of claim 2, wherein the QR/bar code further comprises calibration data.

4. The device of claim 2, wherein the QR/bar code further comprises test device identification information.

5. The device of claim 2, wherein the QR/bar code further comprises lot number information for the device.

6. The device of claim 2, wherein the QR/bar code further comprises an expiration date for the device.

7. The device of claim 2, wherein the QR/bar code further comprises manufacturer information for the device.

8. A system comprising:

an optical chamber device comprising;

a tubular rectangle having a floor panel that covers an opening of the tubular rectangle, the floor panel comprising a raised test bed that receives a test medium;

a top panel comprising an optical lens; and

a light source that illuminates inside the optical chamber device; and

a computing device comprising a processor and memory, the processor executing instructions stored in the memory to;

receive a selection of a test from an application;

based on the test, select a testing protocol;

receive an image of the test medium obtained through use of the optical chamber device; and

process the image with the testing protocol to obtain a test result, the image being processed by;

applying a template outline that comprises a pre-determined field that aligns with the test medium;

detecting a control line on the test medium;

identifying corners of the test medium that define test medium coordinates;

assigning values to each of red, green, blue, and gray colors in the test medium coordinates; and

displaying an array of bars below the control line based on the assigned values;

wherein a bar in the array is identified as a test line when the bar has an increasing value compared to an adjacent bar.

9. The system of claim 8, further comprising the system scanning an area of the image.

10. The system of claim 8, further comprising the system scanning multiple areas of the image.

11. The system of claim 10, wherein each of the multiple areas are evaluated separately.

12. The system of claim 11, wherein each of the multiple areas provide a separate result.

13. The system of claim 8, wherein the computing device comprises any of an iPhone, Android device, iPad, tablet, Personal Computer or a Macintosh.

14. A system comprising:

an optical chamber device comprising;

a tubular rectangle;

a floor panel that covers an opening of the tubular rectangle, the floor panel comprising a raised test bed that receives a test medium;

a calibration matrix disposed adjacent to the raised test bed;

an illumination volume of the optical chamber device;

brackets disposed on each corner of the tubular rectangle, the brackets allowing for selective increasing or selective decreasing of the illumination volume based on placement of the floor panel in contact with a portion of the brackets; and

a computing device comprising

a processor and memory, the processor executing instructions stored in the memory to;

receive a selection of a test from an application;

based on the test, select a testing protocol;

receive an image of the test medium obtained through use of the optical chamber device;

apply a calibration profile for the optical chamber device, the calibration profile being created from an image of the calibration matrix obtained using the optical chamber device; and

process the image with the testing protocol to obtain a test result.
