- Abstract:
- This paper presents a methodology for obtaining digital machine-readable measurements from numerical displays images. The proposed method provides means to automate and digitalize a previously manual and labour-intensive laboratory procedure for flowmeters calibration. The proposed method allows to obtain machine- readable readings from remote numerical displays with available-off-the-shelf hardware and open- source software. By using smartphones for remote image capture and streaming and the Tesseract open-source OCR engine, is possible to leverage the infrastructure’s digital transition, improve procedures efficiency and effectiveness while promoting sustainable actions with cost reductions.
