ANPR project was successfully deployed at BALCO, in this case, we had to detect hand painted number plates of trucks operating in coal mines, the hand painted number plates are hard to be read by standard Tesseract Model, so we trained our own model to achieve good results.
Another concern in this project was change of camera angle due to wind etc, we implemented jackub Sochor’s Vanishing Point method to calculate the angle of camera, which helps in easy error resolution as change in camera angle can lead to problems in ANPR.
