Road entrance automatic card-issuing system and method

Abstract

The invention provides a road entrance automatic card-issuing system. Issuing time is saved. The system has the functions that a motor vehicle runs to a detecting zone and triggers a virtual triggering line (5), and a phase laser range unit (1) and a capturing camera (2) are started to obtain vehicle height data and vehicle image data respectively; a computing and controlling module in a card taking machine (1) carries out processing and analyzing on the vehicle image data and the vehicle height data, front windshield lower edge position parameters and vehicle height are obtained, and then cockpit height is computed; and according to cockpit height computing and control module judging, passing cards are issued through a low position card outlet (42) or a high position card outlet (41). Through an improved Roberts edge detection operator, an original image edge image can be determined accurately, card-out positions can be controlled accurately, a user can take a card conveniently, and then lane capacity is improved.

Description

technical field [0001] The invention relates to the field of vehicle toll collection, in particular to an automatic card issuing system for road entrances. Background technique [0002] With the rapid development of domestic expressways and the increasing number of motor vehicles, people have put forward higher requirements for the efficiency of expressway traffic, and an intelligent expressway toll system has emerged as the times require.

[0006] 3. Due to the different driving skills of each driver and the vertical position of the cab, there is no guarantee that each driver can park the car at a position where the arm can easily press the button to take the card. Some drivers need to get out of the car to take the card, which will affect the traffic efficiency
