In real life, traditional parking lot management is mainly to issue cards to vehicles entering the parking lot or arrange managers to register vehicle information, and record the time of vehicle entry and exit as the main basis for billing. Whether it is a fixed vehicle or a temporary vehicle, you must leave the parking lot after swiping the card at the exit or paying manually. This type of management often leads to traffic jams and wastes the owner's time. In order to solve the above problems, the use of license plate recognition technology to replace the traditional manual card management has an important role in achieving vehicle automation management.
License plate recognition is one of the important components of modern intelligent urban transportation and is widely used. Based on digital image processing, pattern recognition and other technologies, analyze the image or video sequence of the vehicle captured by the camera to obtain the unique license plate number of each vehicle to complete the recognition process.
system structure
The basic hardware configuration of the license plate recognition system consists of a camera, a main controller, a capture card and lighting equipment. The software level consists of image analysis and processing software with license plate recognition and background management software that meets specific application needs.
Manage parking lot access
The license plate recognition device is installed at the entrance and exit of the parking lot, records the license plate number and the time for the vehicle to enter and exit, and combines it with the barrier to realize the automatic management of the vehicle. When applied to parking lots, automatic toll collection can be achieved, and the number of available parking spaces can be automatically calculated and given a reminder. Automatic parking fee management can save manpower and improve efficiency. When applied to a cell, it can automatically determine whether the entering vehicle belongs to the local cell and charge for non-internal vehicles. In some units, this application can also be combined with the vehicle system to automatically record the vehicle's outbound status. The license plate recognition technology is adopted to realize the card-free inspection without stopping, which effectively improves the efficiency of vehicles entering and leaving.
