Dynamic two-dimensional code-based navigation system and method

Abstract

The present invention relates to a dynamic two-dimensional code-based navigation system and method. The navigation system includes a navigation server, a two-dimensional code projection device, a two-dimensional code reader, and two-dimensional code navigation software; the navigation server is used for generating a two-dimensional code containing navigation information; the two-dimensional code projection device communicates with the navigation server, and projects the two-dimensional code received from the navigation server onto the ground; the two-dimensional code reader is mounted on a vehicle and is used for scanning and reading the two-dimensional code; and the two-dimensional code navigation software is installed on the vehicle machine center control system of the vehicle and is used for receiving the two-dimensional code read by the two-dimensional code reader and decoding the navigation information contained in the two-dimensional code. The invention also discloses a navigation system-based navigation method.

Description

technical field [0001] The present invention relates to a navigation system and method, more specifically, the present invention relates to an indoor parking navigation system and method based on a dynamic two-dimensional code. Background technique [0002] Nowadays, with the increase in the number of vehicles, the scale of the parking lot is expanding and the layout is becoming more complex. How to quickly guide users to park has become a headache. In addition, due to problems such as weak indoor GPS signals and low accuracy, it is impossible to accurately guide users to park in empty parking spaces. [0003] At present, there are a variety of parking guidance technologies on the market, mainly divided into several categories: [0004] 1) Roughly guide through the signage; [0005] 2) Carry out prompt guidance by marking the empty parking space with the parking space indicator light; and [0006] 3) Display available vacant parking spaces through acoustic detectors / parki...

AI Technical Summary

Problems solved by technology

[0008] 1) The scheme of rough guidance through signs cannot achieve accurate and real-time route guidance;

[0009] 2) The scheme of prompting guidance by marking empty parking spaces with parking indicator lights cannot be applied to parking guidance in the case of tight parking spaces in large parking lots due to the limited visual range of users;

[0010] 3) The cost of displaying available vacant parking spaces through acoustic detectors / parking cameras / infrared detectors / ground sensing coils and electronic signs is relatively high, and it is impossible to accurately guide vehicles to park

At the same time, the scheme requires a navigation display screen to be installed above the passage in the parking lot so that the driver can find the target parking space according to the orientation information on the navigation display screen, which undoubtedly increases the investment cost of the early stage construction of the parking lot.

On the other hand, in the above scheme, the empty parking space and the vehicle to be parked have been bound in advance. If the parking user A parks the car in another empty parking space, the user B who has obtained the other parking space in advance can only use other parking spaces. Therefore, this scheme of pre-allocating unique parking spaces for vehicles may cause some parking confusion
