Background technique

In recent years, most cities in my country have entered the development track of rapid urbanization, and the level of urban motorization has also increased rapidly, which has brought heavy pressure on urban traffic and the problem of parking has become increasingly prominent. Traffic "difficulty in parking" has increasingly become a "bottleneck" restricting the economic development of large and medium cities. In order to ensure the convenience of vehicle traffic, especially in order to improve the problem of "difficulty in parking", major cities are vigorously building large parking lots to meet the needs of people. Growing demand for parking.

With the continuous emergence of large parking lots, parking management technology has also become one of the number one symbols of current intelligent buildings. However, most of the traditional parking lot management is still manual management. When the vehicles to be parked enter the parking lot, the parking administrator needs to manually check and judge whether the vehicles are parked or not. However, due to the limitations of manual inspection and judgment, it is easy to make mistakes in judgment, resulting in management defects. With the increase in the number of vehicles in the parking lot, the cost of manual management has also increased, and the workload and difficulty of parking administrators They are multiplied, which in turn reduces the efficiency of parking management in the parking lot. It can be seen that the traditional parking management has the problems of low management level, low management efficiency, high labor management cost and management errors, and it is difficult to meet the needs of intelligent planning and management of parking in large parking lots.

SUMMARY OF THE INVENTION

In view of the above problems, the present invention proposes an intelligent analysis and management method for urban traffic parking safety based on video surveillance. By installing parking management equipment on the parking spaces in the parking lot, the parking planning management of the vehicles to be parked can be effectively compensated. The shortcomings of traditional parking lot parking management.
