Use AR technology to wake up the lost civilization Baidu boost AI into life
The artificial intelligence technology that represents the next era is really coming into our lives. Recently, an action initiated by Baidu to restore Chaoyangmen through augmented reality (AR) technology has aroused widespread concern. At the Chaoyangmen subway station, the public used the mobile phone Baidu APP to align with the huge Chaoyangmen hand-painted poster on the wall or on the ground, and then click “Discover AR Animation†to wake up the old city gate. It is reported that this is the first time in China to use AR technology to restore cultural cities, and to conduct large-scale historical and cultural public welfare education in the mobile space. Behind this mature Baidu AR technology application, Baidu is actually a manifestation of deep accumulation in the field of artificial intelligence. From Baidu unmanned vehicles to Duo Mi, Baidu AR, Baidu medical brain, we can easily find out from Baidu's strategic layout that Baidu has been committed to promoting the integration of artificial intelligence technology into our lives.
Baidu uses technology to restore the Chaoyang Gate. After only triggering the AR through the mobile phone Baidu APP, you can see the various life scenes of the people in Chaoyangmen during the Yuan Dynasty and the early Ming Dynasty. At the same time, it can also perform zero distance with the restored Chaoyang Gate. Human-computer interaction. And how is this technology implemented?
Baidu related person in charge said that the Chaoyangmen Old Town door restoration, with the mobile phone Baidu embedded AR plug-in, relying on Baidu image recognition, multi-mode interaction, 3D vision as the core of the mobile AR technology, using sound, 3D model animation, etc. The form vividly presents history and provides an interesting interactive experience for the audience while conveying the old Beijing history and culture.
"Baidu AR has developed rapidly in a short period of time thanks to the deep accumulation in the field of artificial intelligence. Artificial intelligence is the foundation of AR technology, AR needs artificial intelligence technology such as image recognition, face recognition, OCR text recognition, speech recognition, etc. To perceive the real world, to achieve a seamless superposition of virtual objects and the real environment, and to achieve human-computer interaction in the real space, improve the service efficiency of the application products."
It is worth noting that Baidu also selected the Xizhimen Station of the subway and a train on Line 2, during the Spring Festival, “staged†an AR to recreate the historical and cultural experience of the old Beijing nine gates. According to Baidu, the reason why Line 2 was selected is because it is the only subway line that runs through the old Beijing's nine major city gates. In the research and development process of this project, engineers constantly try various technical solutions to optimize the tracking and display effects of the algorithm, which makes the story of the ancient city gate more smooth and stable, and deeply understands the interactive experience of the product, and shows the city gate more realistically. In front of users, more people are really experiencing the cutting edge of artificial intelligence AR technology.
We believe that after the mobile Internet, the next era is the era of artificial intelligence, so Baidu began to invest heavily in artificial intelligence five or six years ago. In an interview with the media, Li Yanhong said that in fact, in the past two years, Li Yanhong appeared almost every time in public, and repeatedly emphasized artificial intelligence.
As one of the earliest companies to deploy artificial intelligence, Baidu established the world's first deep learning research institute in 2013, and later expanded to Baidu Research Institute, which has artificial intelligence laboratory, deep learning laboratory and big data laboratory, recruiting Wu Enda, etc. The top experts in artificial intelligence built the world's largest deep neural network "Baidu Brain", and competed with companies such as Google and Microsoft for the commanding heights of artificial intelligence technology.
On November 16 this year, the 3rd World Internet Conference released the world's leading Internet technology achievements. Baidu's core result of artificial intelligence, Baidu Brain, was successfully selected into 15 leading scientific and technological achievements, becoming the only comprehensive artificial intelligence technology selected in China. The World Internet Leading Scientific and Technological Achievements Recommendation Committee believes that the Baidu brain released on September 1 this year has established a super-large-scale neural network with its leading algorithms, super-computing power, and tens of billions of big data, which can learn and train extremely complicated. The model has the leading ability of voice, image, natural language processing, user portrait, etc., and is widely used in unmanned vehicles, intelligent medical, AR, and secret robots.
Zhang Yaqin, president of Baidu, said that Baidu’s brain consists of three major parts: ultra-large-scale neural network, computing and data, which mainly include voice, image, natural language processing, and user portrait. Among them, Baidu Depth Speech recognition technology Deep Speech 2 was selected in the "MIT Technology Review" '2016 Top Ten Breakthrough Technologies', the speech recognition accuracy rate reached 97%; Baidu's multiple face detection and recognition, OCR competition are the world's first; sentiment analysis, Techniques such as syntactic analysis and named entity recognition are also ranked first in the world in international standard evaluation sets."
At the opening of the Internet, Baidu's choice is to open artificial intelligence technology to help other Internet companies develop and build a healthy and win-win new industry ecosystem. Recently, Baidu announced that its new deep learning open source platform PaddlePaddle is open to the open source community Github and Baidu brain platform for developers to download and use. Baidu has become another technology giant that will open up artificial intelligence technology after Google, Facebook and IBM. It is also the first open source deep learning platform technology company in China.
It is reported that PaddlePaddle's predecessor was Baid's self-developed deep learning platform Paddle (Parallel Distributed Deep Learning), which has been developed and used by Baidu's internal engineers. The deep learning platforms of the world's major technology giants have their own technical characteristics. For Baidu, due to its own business and technology in search, image recognition, speech semantic recognition, sentiment analysis, machine translation, user portrait recommendation and other fields. Direction, PaddlePaddle is more comprehensive and is a relatively full-featured deep learning framework. At the Baidu World Congress on September 1 this year, Baidu chief scientist Andrew Ng (Wu Enda) announced for the first time that Baidu's deep learning platform was opened to the public and named PaddlePaddle.
Xu Wei, a senior scientist at Baidu and the head of R&D at PaddlePaddle, said: "With the help of PaddlePaddle, the design of the deep learning model is as easy as writing pseudo code. The designer only needs to pay attention to the high-level structure of the model without worrying about any trivial underlying problems. In the future, programmers can quickly apply deep learning models to solve practical problems such as medical and financial issues, and let artificial intelligence play the most important role.†Currently, PaddlePaddle has played a huge role in Baidu's 30 major products and services, such as Take-out estimates of meal time, pre-judgment of network disk failure time points, accurate recommendation of users' required information, mass image recognition classification, character recognition (OCR), virus and spam detection, machine translation and autopilot.
In this regard, some insiders said that Baidu, as the earliest company to deploy artificial intelligence, is fully open to help traditional enterprises and developers to upgrade when the next scene of the Internet opens. It is also a manifestation of promoting the entire social and economic development under the new economic normal.
As Li Yanhong said, “These technologies are not only owned by Baidu. We will open it for free for our alliance partners. This can really make artificial intelligence penetrate into various industries and change our society. â€
