AR multi-path navigation system

Abstract

The invention discloses an AR multi-path navigation system which comprises an AR server, a vehicle-mounted end and a road surface live-action map acquisition end, wherein the AR server comprises an ARlive-action database, a 5G signal sending and receiving module and an AR live-action map correction module. For the road image without the road marking line, except that the outermost contour line ofthe road, the sewer well lid, the communication cable well lid and the cable well lid adopt live-action contour lines, other road images are all formed by filling preset road image filling blocks, and all the well lids are also filled with corresponding well lid image filling blocks. Since the images are preset images specially used for filling, the filling images of all the road images are the same, live-action road images of different roads do not need to be stored, and the storage space of the images is further compressed. According to the system, a navigation layer is divided into a plurality of layers, and only less data transmission needs to be carried out all the time when navigation is carried out.

Description

technical field [0001] The invention relates to the technical field of AR navigation systems, in particular to an 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 the so-called 3D virtual nav...

Problems solved by technology

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 navigation equipment, which is not good for consumers or production designers; or in order to reduce signal transmission, reduce the resolution and clarity of AR real-scene images, or compress and The way of decompression is to transmit a smaller data file during the transmission, and at the same time reduce the number of cameras simultaneously, but this also makes the clarity of the final AR real-world image used for navigation not enough, or the data of the sensor vehicle is not accurate enough , and finally lead to poor navigation effect, can not clearly find the scene outside the car or need to spend more observation energy of the user to observe, and even cause danger

[0013] However, in the existing technology, there is no effective technology to solve the above-mentioned problems at the same time, and at the same time provide a low-latency navigation technology with low cost, high navigation efficiency and clear images. Therefore, it is hoped to provide a low-latency Timely and low-cost navigation technology to solve the above problems
