Background
At present, in order to relieve the problem of difficult parking, city managers can set partial parking spaces on two sides of an urban road, so that drivers can conveniently drive. Urban roadside parking (also called roadside on-road parking or in-road parking) is always a difficult problem of urban management, and the parking spaces are characterized in that: the parking direction of the vehicle is consistent with the direction of the road, and the front vehicle and the rear vehicle can mutually shield license plates, so that the problem of poor visual angle is brought to a manager. Roadside parking lots in cities are generally full-open parking spaces, vehicles can enter and exit without being restricted by a barrier gate and the like, and are generally managed manually or manually through an auxiliary PDA (personal digital assistant) at present, so that the problems of nonstandard parking charging, low timing precision, charge omission, charge disorderly, insufficient evidence obtaining, difficulty in tracing, incapability of all-weather management and the like exist. Under the condition of worker's management, the parking stall that every toll collector can manage in fact is extremely limited, 6 meters calculate to the standard parking stall length of a roadside parallel parking (the direction of parking is on a parallel with the road direction, the locomotive connects the car tail mode, also known as a style of calligraphy parking), the length of 20 parking stalls is more than 120 meters, because this type of roadside parking stall is after the vehicle stops steadily, there is the problem of sheltering from the visual angle around the existence, often be difficult to the license plate of static observation many cars, it surveys the evidence to need personnel to come and go the target parking stall closely repeatedly, bring huge work load for the management, there are working strength big, low working efficiency, personnel's potential safety hazard scheduling problem.
In recent years, partial cities try on roadside parking management based on a geomagnetic sensor, and whether a parking space is occupied or not is determined by providing a trigger signal through the geomagnetic sensor buried in the parking space.

As shown in fig. 1, roadside parallel parking management is generally sequential management, and a plurality of mounting posts are often disposed along a road, and in order to avoid interference of headlights of a vehicle with a camera device or interference of fill lights of the camera device with a driver in front (this behavior is prohibited in some cities), the camera devices of the respective mounting posts are generally disposed in a superimposed manner in a mode of shooting from the tail direction of the vehicle. Generally, among the management of the parallel parking of roadside, every installation pole is generally highly about 6 meters, and every installation pole can manage a plurality of parking stall, and when a plurality of parking stalls were managed to every installation pole, the distance between the installation pole was elongated, and the vehicle on the distal end parking stall can appear overlapping sheltering from, can't judge basically whether have the vehicle on the parking stall that is sheltered from, consequently brings the difficult problem of image source for detecting image target and parking management, has seriously restricted the reliability of this scheme and the ability of managing more parking stalls.
