Method and system for detecting vehicle exit and entrance states

Abstract

The invention discloses a method and system for detecting vehicle exit and entrance states. The method comprises the steps that when a vehicle license plate recognition device recognizes the license plate of a vehicle, the vehicle serves as the first vehicle, a first counter records one, and a timer with scheduled time is started; whether the vehicle license plate recognition device recognizes a next license plate within the scheduled time or not is circularly detected; if yes, one is added to the count of the first counter, and whether the next license plate is the same as that of the first vehicle or not is judged, if yes, one is added to a second counter, otherwise, zero clearing is conducted on the second counter; whether numerical value of the second counter is larger than a threshold or not is judged, and if yes, predetermined state information is output; otherwise, the numerical value of the first counter is compared with all predetermined numerical intervals, the predetermined numerical interval corresponding to the numerical value of the first counter is determined, and state information corresponding to the predetermined numerical interval which corresponds to the numerical value of the first counter is output; the through efficiency can be improved, and the use ratio of an exit and an entrance and lanes is increased.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and system for detecting the status of vehicle entrances and exits. Background technique [0002] At present, license plate recognition equipment has been widely used in parking lots, urban roads, expressways and other areas for automatic capture and recognition of vehicle license plates. Large commercial and property parking lots will have multiple entrances and exits, and each entrance may have more than one exit or entry lane. [0003] There is no exit state detection and display in the current parking lot, which brings a lot of inconvenience to users. For example, when a user wants to drive out in the parking lot, he cannot know the current traffic status of each parking lot entrance and exit, that is, whether it is busy or whether there is an abnormal event. If it is known in advance that a certain entrance and exit is currently in an idle state, the user can select...
