Telechroma
Smart colorimetric analyzer for telemedicine applications — uses computer vision to quantify color changes in diagnostic test strips remotely. GitHub repo available.
Telechroma is a smart colorimetric analyzer built for telemedicine applications. It uses a camera module and computer vision algorithms to quantify color changes in paper-based diagnostic strips (e.g., urine dipsticks, lateral flow assays), enabling remote diagnostics without expensive lab equipment.
How It Works
- A user places a diagnostic test strip in front of the Telechroma device.
- The embedded camera captures a standardized image under controlled lighting.
- Computer vision algorithms segment the test pad regions and extract color values (RGB/HSV).
- Colorimetric analysis maps extracted color readings to analyte concentrations using calibration curves.
- Results are transmitted to a telemedicine platform for physician review.
Key Features
- Standardized illumination: Reduces inter-device variability in color measurement.
- Automated pad segmentation: Locates and isolates individual test pads using contour detection.
- Concentration mapping: Translates color intensity to clinically meaningful values (e.g., glucose, protein, pH).
- Remote reporting: Results sent via serial/Bluetooth to a connected device.
Technologies
- C++ (embedded firmware)
- OpenCV for image processing
- Arduino microcontroller
