Parking lot parking guidance method based on vehicle secondary identification

Abstract

The invention relates to a parking lot parking guidance method based on vehicle secondary identification. The method includes: obtaining a vehicle license plate image when a vehicle enters a parking lot, identifying a license plate number, and judging whether the vehicle is a new vehicle on the basis of the license plate number; if the vehicle is a new vehicle, recording vehicle information, setting the vehicle as a second-type vehicle, and recording parking information this time; if the vehicle is not a new vehicle, calling historical parking records of the vehicle, and classifying the vehicle on the basis of the queried historical parking records; conducting targeted parking guidance for different types of drivers, and sending an optimal parking route to a display device for display, sothat a vehicle driver can arrive at a target parking stall according to the displayed optimal parking route. According to the invention, the parking efficiency and the utilization rate of parking stalls are improved, and parking accidents are reduced at the same time.

technical field [0001] The invention relates to a parking guidance method in a parking lot based on secondary identification of vehicles. Background technique [0002] At present, the management of the parking lot is mostly aimed at the automatic identification of the license plate of the entering vehicle, the management of the entry authority of the vehicle, automatic billing and payment, etc.; for the vehicle to find a vacant parking space in the parking lot, the guidance of the vehicle parking route, and the safety of the vehicle parking, etc. There are still some deficiencies in the aspect, which leads to problems such as difficulty in finding parking spaces, disorderly parking of vehicles, and low parking efficiency in existing parking lots.

Problems solved by technology

[0002] At present, the management of the parking lot is mostly aimed at the automatic identification of the license plate of the entering vehicle, the management of the entry authority of the vehicle, automatic billing and payment, etc.; for the vehicle to find a vacant parking space in the parking lot, the guidance of the vehicle parking route, and the safety of the vehicle parking, etc. There are still some deficiencies in the aspect, resulting in the existing parking lot has problems such as difficulty in finding parking spaces, disorderly parking of vehicles, and low parking efficiency.

[0003] In the prior art, although there are parking lots that indicate vacant parking spaces through display screens, the following problems may occur due to the inability to accurately guide specific drivers;

[0004] 1) When the width of the parking space is narrow, it is easy to cause collisions between vehicles during parking;

[0005] 2) Traffic congestion in the parking lot caused by drivers parking for too long at the main road or intersection leads to low parking efficiency;

[0006] 3) Parking across parking spaces or crossing parking spaces at parking spaces close to walls or pillars leads to waste of parking resources
