Motor vehicle passage check system with license plate number recognition and vehicle appearance verification

Senesys-Avto is a system for automation of vehicle passage check as well as check of vehicle presence on the guarded territory.

A surveillance camera mounted at the checkpoint registers an approaching vehicle. The video data are transmitted to the ‘Auto-Number’ server where the license plate number is analysed after pre-processing the received video image. The recognized license plate number of the vehicle as well as the information about the license plate type and the identifier of the corresponding channel are transmitted to a server of Senesys system.

Senesys system checks whether the approached vehicle is in the database. If it is registered and has a right to pass, a command to open the lifting gate will be given, otherwise it will be proposed to add the vehicle to the database, open the executive device manually or deny access.

The event of passage as well as all operator’s actions are recorded in the event log.

The appearance verification module connected to Senesys system prevents manipulations with license plate numbers. The image of a vehicle received from a video surveillance camera is compared to the image of the vehicle to which the recognized license plate number belongs according to the database. If the images do not match, a warning is sent to the operator.
