Abstract: Character recognition is the key step of vehicle license plate recognition (VLPR).Some concepts,such as shape feature vector (SFV),were proposed after examining the character set used by vehicle license plate and the feasibility of using SFV to recognize vehicle license plate characters was proven theoretically.Then,a character recognition algorithm of vehicle license plate was proposed and evaluated by simulation.The result of the simulation shows that SFVcan be used as license plate character recognition,and the license plate recognition algorithm based on SFV has an accuracy rate of 97.31%.Besides,this algorithm has no complex training process and does not require large amounts of data to record the training results.It is simple to implement and is a lightweight license plate character recognition algorithm.

Key words: Character recognition, Shape feature vector, Vehicle license plate recognition
