Baidu AI Map Power 5G: Users, Vehicles and Traffic go hand in hand


The landing of 5G technology is regarded as a prelude to the change of various industries.
With the help of AI technology, Baidu Map will be upgraded to a new generation of AI Map in 2018, and Baidu Map will go farther and farther in the direction of Black Technology Help Map. 5G technology is a forward-looking opportunity it smells again.
On July 27, at the 5G Future Industry Conference of GMIC Global Mobile Internet Conference in 2019, Li Ying, general manager of Baidu Map Business Department, delivered a keynote speech entitled “A New Generation of Artificial Intelligence Maps: The Leader of the 5G Age”.
Li Ying believes that in the 5G era, map products will tend to be more refined, authentic and intelligent. 5G and AI have shown a trend of deep integration, and intelligent travel will have greater imagination space in the future.
Based on the technology of Baidu Brain 5.0 version, Baidu Map will focus on high-precision positioning, super-fine rendering, wake-free voice interaction and other technical fields to build a more intelligent urban transportation system for the future.
The map meets AI
Map industry is the battlefield of BAT, and its function is becoming more and more mature. But Li Ying said that users still have a lot of pain points in the use of maps.
For example, in the process of driving, manual and map interactive navigation is not only cumbersome and unsmooth, but also has potential safety hazards to distract the owner’s attention. Using voice interaction function, a simple instruction can replace manual interaction.
“Voice interaction is very important for map navigation, which is one of the reasons why Baidu Map chose AI technology as a breakthrough. Map is the basic ability of AI and the most typical landing scene of AI.
Clear in-car speech recognition is a challenge in the presence of noise. Li Ying said that from the use of scenarios, voice interaction can be divided into three stages: listening, understanding and satisfying. This requires a very profound understanding of voice broadcasting and natural language processing behind the dialogue system.
At last year’s Baidu AI developer conference, Wang Haifeng, Baidu’s chief technology officer, issued a 60-word instruction on the spot, and Baidu Map’s “small” voice assistant accurately completed the task. “This is not a dazzle, but to tell you that voice interaction is very complex.”
Thanks to Baidu’s support, the embedding of AI technology seems to be a natural thing. At Baidu AI Developers’Conference in July, Li Ying introduced that Baidu Map ETA (Intelligent Travel Time Prediction) has been effectively improved after the application of Baidu Deep Learning Platform (Baidu Deep Learning Platform) paddle. Users can accurately grasp the current and future travel time.
With the support of AI technology, the number of users of Baidu Map Intelligent Voice Assistant has exceeded 250 million, which has increased by 1.5 times in one year. At present, Baidu Map has responded to 120 billion requests for location and route planning on a daily basis, providing global positioning services to more than 200 countries and regions worldwide.
At the beginning of July, Baidu Brain officially upgraded to version 5.0, becoming a software-hardware AI production platform. While integrating AI algorithm, computing architecture and application scenarios, Baidu Brain combines in-depth learning with open source platform, making AI production platform, AI algorithm innovation go hand in hand with voice, vision, language and other technologies. In terms of arithmetic, Baidu’s Kunlun and Honggu chips mark a new step in Baidu’s arithmetic.
In addition, the white paper of AI edge computing technology, OTE system of edge computing, Baidu Intelligent Edge 2.0 and the successive release of three kinds of intelligent edge hardware show that Baidu has carried out a comprehensive layout on the eve of the 5G era.
Client: AI Map Enhances User Experience
For map products, precise positioning is its core function and the primary guarantee of all functional experience. It is also the “basic skill” that mobile map must be constantly consolidated. In the daily driving process, erratic map positioning often occurs in tunnels or viaducts with weak signals.
To this end, Baidu Map, through GPS and WIFI positioning information fusion inertial navigation technology and in-depth learning technology, has introduced Baidu Intelligent Positioning Function, which can carry out positioning estimation and continuous navigation without signal. Its precise planning function can achieve the “God’s perspective” of global route navigation planning and improve travel efficiency. 。
With the arrival of 5G era, high-density network base stations can effectively increase the stability of network signals and the amount of information of location, so as to achieve high-precision indoor positioning and high-precision visual positioning of sub-meter level.
In addition, with the support of 5G technology, the voice interaction function of Baidu Map is expected to be strengthened. It is understood that Baidu Map has now realized the “full voice control” of the client, and can successfully complete interactive actions in complex scenarios such as Long-Sentence question-and-answer, navigation query and so on.
Li Ying told Leifeng Xinzhijia: “Baidu Map now has more than 700 voice skills, that is, more than 700 voice commands can be recognized.” 5G can provide a more stable network environment, Baidu Map can achieve voice “wake-up-free” in more complex travel scenarios, and further innovate the way users interact with the map.
In addition to intelligent location services and voice interaction functions, Baidu Map is also exploring how to depict the real world. At present, Baidu Map has taken the lead in the industry in exploring regional scenery and road fine rendering, constantly improving the refinement level of map images.
Leifeng Xinzhijia learns that Baidu Map has made an attempt to reproduce the “3D Yuanmingyuan Water Law” using AR black technology in the latest map APP. Scanning the site with Baidu Map, users can see the same proportion of Dashui site in their mobile phones, change the camera position by moving their feet, and watch the 360-degree Dashui scene.
According to Li Ying, in the future under 5G network, Baidu Map will be able to obtain more abundant and real-time basic geophysical information data, thus ultimately realizing fine-grained, high-fidelity and ultra-fine depiction of the real world.
Vehicle End: Evolution of Baidu Map in Vehicle
In addition to providing C-end user services, industry-oriented map location information service is also a battlefield that map manufacturers attach great importance to.

By integrating Map Auto designed specifically for driving scenarios, Baidu Map launched a locomotive map suitable for automobiles in 2018, which has become an important part of the automobile networking ecology of main engine factories. At present, we have different degrees of cooperation with BYD, Hyundai, Kia, Chery, Dongfeng Automobile, Tengzi, Weima, Weilai and other main engine factories.
With the rapid development of automatic driving technology, Li Ying told Leifeng Network (public number: Leifeng Network) Xinzhi Driver that Baidu’s high-quality map and automatic driving are realizing deep integration. The acquisition and supply of high-precision maps for Baidu Apollo UAV are all based on maps as business integration end. Apollo also puts forward the demand for Baidu Map from the real product demand dimension and product supply dimension, and invests part of human resources at the same time.
At the developer’s conference, Wang Haifeng pointed out that “80% of the data acquisition links of Baidu Map have been AI-based, and the whole process of information acquisition, data acquisition, data production and dynamic correction has been AI-based. The process of map data production has been redefined.” With the advent of 5G era, Baidu Map will be further integrated with on-board and automatic driving.
Transportation: Intelligent Map Enables Intelligent Transportation
From the traffic level, map as a geographic information product is also an important link of urban traffic management. Faced with the current “congestion disease” in big cities, Baidu Map also gives a “way to resolve it”.
Through the construction of data layer, service layer and application layer, Baidu Map has formed a traffic data platform which integrates the perception and fusion ability of traffic big data. On this basis, with Baidu AI, driverless and big data as its core competence, it provides algorithm model, data subscription, decision learning, command and dispatch. Big services eventually form three types of applications:
User-oriented: Authoritative information release solutions for users;
For government departments: to provide urban traffic management command and dispatch solutions;
Partner Oriented: Provide more vertical solutions for public transport, high-speed, logistics, scenic spots and other scenic spots.
Baidu Map believes that traffic light allocation and intelligent signal lights are the grasp of congestion solutions. Therefore, Baidu Map is continually researching solutions for intelligent traffic lights: providing traffic police and signal control industry practitioners with deadlock and overflow alarm at intersections, optimization and evaluation of signal timing, together with the speed of road trajectory and traffic flow, forming a set of solutions for traffic lights.
At present, Baidu Map has been partially practiced in Beijing and Dalian. The practice results of Houchangcun Road in Beijing show that the peak congestion index of the whole day has dropped from 4.60 to 3.94.
In addition, Baidu Map’s traffic information publishing and judging platform can provide real-time urban congestion index and congestion section for traffic police command center. Traffic police management can collect and distribute information with the help of platform. At the same time, the platform can distribute information to users through the client of Baidu Map.
To solve the problem of autonomous parking, Baidu Map put forward corresponding solutions. It is understood that Baidu Map has created a complete set of closed-loop parking system, which includes searching parking spaces, booking parking spaces, guiding parking spaces, recording parking spaces, reverse searching, online payment and final departure, to provide users with full-scene intelligent parking solutions.
At present, the scheme has landed in Yinchuan and accessed dynamic data of 100 parking lots in Yinchuan. As a whole, the search time of vehicles for Yinchuan citizens is reduced by 10%.
In the future, 5G will accelerate the landing of Baidu Map Intelligent Transportation. Intelligent signal lamp solution can not only realize intelligent control of traffic lights, but also enable users to have “thousands of miles” to see the traffic lights in front of the intersection in real time; Baidu Map Traffic Information Publishing and Research Platform also enables relevant departments to get more timely, more detailed and detailed temporary changes in urban traffic, unexpected situations. Automatic parking schemes are also expected to improve urban traffic efficiency and the parking experience of citizens.
Upgraded to a new generation of AI maps, Li Ying used the words “more accurate, richer and easier to use” to summarize the product power of Baidu Map. Li Ying said that whether it is AI technology or the upcoming 5G era of Baidu Map, these words still apply, “but the extension will continue to change.”
As an indispensable cartographic product in 5G era, map depth integration AI technology is expected to innovate people’s way of travel. But Li Ying also said that Baidu Map is still in the stage of 5G. How to connect the new technology more quickly and how to practice it after the emergence of new technology is still a big challenge.
