Low-delay high-definition AR multi-path navigation system

Abstract

The invention discloses a low-delay high-definition AR multi-path navigation system, which comprises an AR server, a vehicle-mounted terminal and a road surface live-action map acquisition terminal, wherein the AR server comprises an AR live-action database, a 5G signal sending and receiving module and an AR live-action map correction module; the vehicle-mounted terminal comprises a local AR live-action database, a 5G signal sending and receiving module, a camera module, an AR live-action image display module, a vehicle-mounted terminal processor, a vehicle-mounted terminal positioning moduleand an Internet-of-vehicles RFID sensing device. The pavement live-action map acquisition terminal comprises a pavement live-action map acquisition module, a carrier, a local AR live-action database,a vehicle-mounted terminal positioning module and carrier RFID sensing equipment, and the carrier is provided with the pavement live-action map acquisition module; according to the method and the device, a navigation layer is divided into a plurality of layers, and only less data transmission needs to be carried out all the time during navigation, so that the construction cost is reduced, and theadverse effect of time delay is reduced.

Description

technical field [0001] The invention relates to the technical field of AR navigation systems, in particular to a low-latency high-definition AR multi-channel navigation system. Background technique [0002] With the development of electronic technology, people began to live a faster and more convenient way of life. Nowadays, with the development of my country's economy, self-driving cars have become an increasingly indispensable part of people's lives. However, when we drive to a certain destination, due to the large and complex city or region, people cannot recognize the route, which brings inconvenience to life; however, with the development of navigation technology, the use of navigation systems for navigation Query the route to the destination, which brings convenience to people's life. [0003] In the prior art, the navigation system includes Baidu map, Gaode map and 360 map, etc. However, these navigation maps are displayed to the user in the form of a flat map, or t...

However, the system suffers from rendering quality that is far from perfect

[0011] However, in order to realize AR navigation, especially immersive AR navigation, more cameras are necessary to obtain more scenes outside the car, and at the same time, local queries or even online queries are required. In this way, the transmission and query of images, especially high-definition images, It will inevitably lead to time delay. For high-speed cars, the delay of data may bring trouble to the wrong intersection, or even advance or delay the turn in the wrong lane, which will bring terrible consequences. This provides a low-latency navigation, which is of great significance

[0012] In order to reduce the time delay of data transmission, the usual method is to increase the bandwidth of information transmission, which can provide a larger data signal transmission channel to transmit high-definition AR images for navigation or image information captured by multiple cameras, but This will inevitably lead to an increase in the cost of AR real-scene nav
