In recent years, as the number of vehicles has been increasing annually, issues such as difficulty in finding parking spaces, traffic congestion within parking lots, slow turnover of temporary spaces, low space utilization, and rising management costs have become increasingly prominent during the daily operations of large and medium-sized parking lots. As a crucial management facility and technical solution for rationally allocating vacant parking spaces and addressing parking challenges, the parking guidance system is being adopted by an increasing number of parking facilities. The video-based parking guidance system is a self-developed and manufactured intelligent parking guidance and reverse navigation system specifically designed to address problems such as outdated parking lot management practices, difficulties in parking and finding spaces, traffic congestion, slow space turnover, and low space utilization.

The video parking guidance system is based on advanced video image recognition and processing technology. It utilizes high-definition parking video detection terminals to monitor parking space status in real time and uploads detected data such as vehicles and parking spaces to a backend management platform. After unified processing, the platform transmits effective parking information to front-end guidance displays, enabling drivers to instantly locate available spaces and park quickly, thereby automatically achieving parking guidance. Additionally, via mobile devices or self-service parking retrieval terminals, drivers can swiftly and accurately find their parked vehicles, fulfilling the reverse parking retrieval function.

1. Features of the Video Parking Guidance System:

1.1 Advantages of Regionalized Management: Equipment or network failures do not spread beyond individual zones and do not affect the normal booting of the system;

1.2 Precision: The video detection terminal is equipped with an inbuilt license plate recognition algorithm, achieving an accuracy rate of over 99% for license plate recognition and over 99% for parking space detection;

1.3 Stability: The entire parking lot is managed through zonal division, where several parking spaces are grouped into independent zones via on-site controllers and mechanical parking space controllers for parking space information collection

1.4 Diversity: The video parking guidance system supports vehicle detection for flat parking spaces. For mechanical parking spaces, it can be used in conjunction with the urban intelligent wired ultrasonic system to achieve parking space status inspection and license plate recognition for mechanical parking groups

Adapt to various types of underground parking lots;

1.5-speed vehicle retrieval enhances parking lot turnover rates while improving user experience.

High-definition video parking guidance can simultaneously detect up to six adjacent parking spaces. Through core technological innovations such as vehicle face recognition, license plate recognition, parking space identification, image distortion calibration, and license plate focal exposure, the system achieves ultra-high license plate recognition rates under various lighting conditions. It effectively identifies unmarked vehicles and those with obscured license plates while featuring parking space reverse lookup and parking space recording capabilities. Utilizing a hand-in-hand POE connection method, it reduces costs and simplifies installation, with integrated navigation functionality. Combined with AI-powered deep learning recognition technology, the system achieves more accurate parking space identification and enhanced environmental adaptability.

2、 Advantages of using high-definition video parking guidance:

2.1 The parking space detector adopts a screw free design and has no limited lifespan;

2.2 The appearance is novel and elegant, matching the sense of grade and design of the parking lot;

2.3 Directly embed embedded recognition algorithms and integrated indicator light control in the parking space detector, with higher reliability and stability in the front-end recognition+control light mode;

2.4 Directly embed the focus exposure algorithm into the parking space detector, supporting clear image capture under low light conditions, suitable for sensing energy-saving light scenes, and ensuring recognition rate;

2.5 Directly embed multiple recognition algorithms into the parking space detector, such as license plates, parking spaces, car faces, neural networks, etc., to improve the vehicle recognition rate

2.6 Adopt integrated seven color indicator lights to distinguish different types of parking spaces, with beautiful and accurate indication effects;

2.7 Adopting wireless WIFI networking method to directly communicate with PC servers, powered by 220V, with simple network topology, easy installation and maintenance;

2.8 Optional suspension installation mode, which is simpler and more aesthetically pleasing compared to bridge installation mode, with a strong sense of grade and design;

2.9 Support parking space recording function, support intelligent recording that only saves the video of the vehicle entering and leaving the parking space, making it easy to track and avoid disputes with the vehicle involved in the collision; Upgradeable intelligent video analysis for timely reporting of abnormal parking situations

2.10 adopts image distortion calibration algorithm, which can simultaneously process 3 parking spaces on one side. It supports the installation of 1 parking space detector in the middle of the road, corresponding to a total of 6 parking spaces on two sides, reducing the number of multiple system configurations and enhancing system stability.

Nowadays, the scale of commercial centers is getting larger and larger, with some even exceeding 10000 parking spaces. Car owners should try to park their vehicles in parking spaces near their destination as much as possible, otherwise they will take many wrong paths, which requires guidance from the parking lot area. During peak hours, it is often difficult to find a parking spot, which requires parking guidance. After parking the car, it was found that there was no clear direction to the exit/elevator entrance. At this point, the importance of navigation becomes prominent. Outdoor, we can use GPS for positioning and navigation, while indoor, we need to use Beacon navigation. High definition video parking guidance is the solution for large commercial center parking lots.
