Hi all,
I can tell you that the spacing of letters/ numbers makes No difference to ANPR; the computer imagery identifies shapes of letters, not the spaces between them. Furthermore, as a vehicle passes the camera, a picture is taken digitally, and the operator then checks it visually to ensure that the computer has identified the correct number. The amount of times the camera picks up TTTTT11111, or similar, when passing central armco barriers is unbelieveable. The system is not designed to identify incorrect numbers. If the above incorrect number is falsely identified, the system simply reads "no trace PNC". For plates where the driver uses italics or similar, the picture which was taken will be looked at by the operator, and manually input onto the system. I know that it is illegal to change the spacing on number plates, and so does everyone else, and choosing to break the law is a personal matter, but I reckon that trying to make numbers read as letters and changing the spacing looks so naff. I can't understand why anyone would pay to look so desperate.
