Two options :


Use pre-built libraries for OCR + Bounding Box detection   (E.g.: https://www.pyimagesearch.com/2018/08/20/opencv-text-detection-east-text-detector/ for Bouding Box detection and then OpenCV / Tessract for OCR)





Train a Deep learning model for Text Detection in scene . Examples : https://github.com/qjadud1994/CRNN-Keras  and https://github.com/mvoelk/ssd_detectors
