The problem
Battery test information was captured as a sequence of screen photos, rather than a dataset ready for charting.
What I built
I built a computer vision tool that reads the test values from the images, puts them in chronological order, and turns the readings into a chart across the full discharge.
The result
The output is a battery capacity chart derived from the photographed readings. The project demonstrates an image-to-data-to-chart workflow.
