Description
Technical Field
The invention belongs to the technical field of urban traffic parking management, and particularly relates to an intelligent analysis management method for urban traffic parking safety based on video monitoring.
Background
In recent years, most cities in China enter rapid urbanization development tracks, and the urban motorization level is rapidly improved, so that heavy pressure is brought to urban traffic, and the parking problem is increasingly prominent. The traffic 'parking difficulty' increasingly becomes a 'bottleneck' restricting economic development of large and medium cities, and in order to ensure vehicle traffic convenience and especially to improve the problem of traffic 'parking difficulty', large parking lots are vigorously built in various large cities so as to meet the increasing parking requirements of people.
With the continuous emergence of large parking lots, the parking lot management technology also becomes one of the first signs of the current intelligent buildings. However, the traditional parking lot management mostly belongs to manual management, when a vehicle to be parked enters the parking lot, whether the vehicle is parked in a standard mode or not needs a parking manager to manually check and judge, meanwhile, the parking prompt needs to be re-specified for the vehicle which is parked in an irregular mode, the manual checking and judging is limited, the judgment error condition easily occurs, and therefore the management defect is caused, the number of the vehicles in the parking lot is increased, the cost of manual management is increased successively, the workload and the difficulty of the parking manager are increased in multiples, and the parking management efficiency of the parking lot is further reduced. Therefore, the problems of low management level, low management efficiency, high manual management cost and management errors of the traditional parking lot parking management are solved, and the parking intelligent planning management requirement of a large parking lot is difficult to meet.
