license plate recognition system < / a > statistical method of recognition rate

1. Recognition rate of natural traffic flow = total number of correct recognition of full license plate / total number of actually passing vehicles

2. Percentage of recognizable license plates = total number of license plates correctly read manually / total number of vehicles actually passed

3. The correct recognition rate of the whole license plate that can be recognized = the total number of license plates correctly recognized by the whole license plate / the total number of license plates manually read. These three indicators determine the recognition rate of the license plate recognition system. Such as reliability and false recognition rate are the intermediate results in the process of license plate recognition
