Shulou(Shulou.com)12/24 Report--

Recently, Amap announced that its lane-level navigation services based on cutting-edge technologies such as Beidou satellite navigation system, deep learning model, inertial navigation and ubiquitous signals have so far supported the use of roads in more than 99% of cities and townships in China.

This means that from now on, users can enjoy this new generation of high-tech-intensive and immersive navigation products when driving, whether in cities or towns, on expressways or on ordinary roads.

And this is by far the largest lane-level navigation service in the world.

As an information service with a long history, navigation products have existed in the market for more than 20 years. After many iterations of technology and product models, navigation products have become an indispensable part of people's lives. Amap, as a leading solution provider of digital map content, navigation and location services, has been committed to applying various scientific and technological innovations, especially domestic and independently developed cutting-edge technologies, to civil transportation for many years to provide a better travel experience.

Lane-level navigation is a typical case, which is in a leading position even on a global scale. For example, since 2020, based on the Beidou satellite navigation system, combined with the correction information of the reference station, the lane-level positioning of some cities and roads has been realized after fusion and solution, and this technology has landed on the smartphone for the first time. It has become a typical application of Beidou, a domestic high-tech in the field of civil travel. Now, the lane-level traffic incident early warning and reminder has been further realized, including abnormal road occupation, sudden braking or slow driving in front, and incoming vehicles at the confluence entrance, so as to facilitate users to know the hidden danger information of the lane level as soon as possible.

And for today's hottest deep application of artificial intelligence technology-- Gaode self-developed deep learning model, it can realize 3D automatic modeling of the integration of the whole road network, in an efficient way never seen before in the industry. batch, large-scale realization of building roads, natural environment, urban landmarks and other elements in Amap fully automated three-dimensional mapping On the other hand, the AI dynamic scene technology, which is based on massive data calculus training and driver-oriented human factor engineering, can dynamically adjust the navigation picture closer to the driving perspective according to the current position and road shape, and build a virtual and real digital world, so that users can quickly correspond what they see and navigation screen more efficiently in the navigation process, and gain the WYSIWYG "second understanding" experience.

Now, with the lane-level navigation basically completed the coverage of the national road, Gaode has also achieved the achievement of building the largest digital map on a global scale by applying AI automatic modeling technology.

In addition, Gaode's lane-level navigation also contains a series of techniques to optimize the navigation experience: inertial navigation, which integrates multiple data construction algorithms such as accelerometers, gyroscopes and magnetometers, to help users ensure navigation continuity even when satellite signals are obscured. Ubiquitous signal technology can simultaneously deal with the signals of cellular network, Wi-Fi hotspots and even the surrounding environment, and convert them into additional clues to achieve positioning continuity in the process of high-speed navigation; there is also over-the-horizon technology, which can automatically deal with the occlusion relationship between roads and buildings, carry out real-time perspective rendering, and carve the navigation experience as much as possible from the point of view of details and humanization.

At present, Gaode lane-level navigation supports most mainstream mobile phones. You only need to upgrade Amap's App to the latest version to experience the service during driving navigation without additional settings.

In the future, Amap will also continue to improve in the field of sophisticated technology and apply it to the travel services that everyone needs in daily life-connecting to the real world, creating more technology products such as lane-level navigation, and making a living map.
