The invention relates to the field of license plate recognition via virtual checkpoints, in particular to a method for parallelly recognizing license plates via a virtual checkpoint. The method comprises the steps of: initializing service, and acquiring a real-time bare code stream; decoding the bare code stream to obtain corresponding paths of video streams, adopting a parallel multithreading method to obtain and store vehicle passing pictures of the video streams, and storing corresponding picture information in the form of character strings into a vehicle passing information queue; adopting a license plate recognition algorithm for parallelly recognizing license plates of the vehicle passing pictures; and storing recognition result information in the form of character strings into a JMS middleware, and the recognized license plate pictures are stored in an FTP server. The method can guarantee the purpose of streamlined comprehensive processing of the video streams while ensuring response real-time performance of system data transmission, has higher system resource availability, and can effectively improve system processing speed and rate.
