The document describes a system developed by Joanna Szadkowska to acquire instrument data using a mobile phone camera. The system uses computer vision techniques to process frames from videos or images taken of a device screen with a mobile phone camera. It detects regions of interest on the screen, crops those regions, and applies optical character recognition to extract the measurement data, saving it to a text file. Evaluation of the system showed it was able to accurately detect regions of interest and recognize text in over 90% of cases across different image sources and conditions. Some factors that could impact the accuracy are transitions between readings, camera movement, lighting conditions, and image/video resolution.
