The 2023 World Internet of Things Expo is held, and Youdao Zhitu's cutting-edge technology practice promotes industry development

From October 20th to 23rd, the 2023 World Internet of Things Expo with the theme of "Intelligent World, Integration and Empowerment" was officially held in Wuxi, Jiangsu. At the Intelligent Sensing Technology Application Development Forum held on October 22, Lai Jie, deputy general manager of Youdao Intelligent Driving Center, delivered a keynote speech on "Application of Intelligent Sensors in Autonomous Driving". He said that perception is the key to automatic driving. A key part of driving research and development, the Honghu intelligent driving platform developed by Youdao Zhitu has the world's leading technical strength in aspects such as ultra-long-distance sensing. In the future, it will invest more energy in technological innovation and promote the technological development of the autonomous driving industry.

Smart sensors are the "eyes" and "ears" of smart driving. Through smart sensors, vehicles can sense the surrounding environment, realize real-time traffic monitoring, obstacle recognition and other functions, and provide accurate and real-time data support for the autonomous driving system. With the rapid development of intelligence and electrification, the demand for autonomous driving sensor configurations continues to increase. Sensors need to be continuously optimized in terms of detection range, accuracy, and capabilities to adapt to more edge scenarios. A single sensor alone cannot meet the needs of high-end autonomous driving. The system's demand for environmental perception, and the current road traffic environment is becoming increasingly complex, making autonomous driving's requirements for perception technology more stringent.

At the meeting, Lai Jie shared the cutting-edge implementation experience of Youdao Zitu multi-sensor sensing and fusion. According to him, as the first self-driving science and technology enterprise in China to realize the verification of "truly unmanned" technology and launch regular test operations, Youdao Zitu has 1,000 meters beyond visual range sensing, multi-sensor fusion sensing decision-making, and anthropomorphic Industry-leading L4 autonomous driving technology such as autonomous driving, overtaking parking, and five-vehicle platoon driving can realize 360° dynamic target recognition in all scenarios, support passable space detection, traffic sign recognition and other functions, ensuring all-weather, all-scenario real-time environment perception.

Currently, Youdao Zhitu's multi-sensor sensing and fusion technology has been applied in many commercial vehicles such as L4 smart heavy trucks and AIV horizontal transfer vehicles. Taking the L4 smart heavy truck, a product of Youdao Zhitu, as an example, it adopts a multi-lidar sensor number coverage solution and is equipped with 5 lidars for large-scale and long-distance environmental perception, close-range blind spot detection and vehicle body corner detection. In addition, Multi-sensor fusion perception decision-making is used to further improve autonomous driving perception fusion. In terms of visual dynamic perception, Youdao Zhitu has a variety of technical capabilities such as visual 3D perception, occlusion target detection, extremely close range perception, and multi-task model development; in terms of visual static perception, the lane line detection distance is greater than 250m and can identify 30 More than one kind of traffic signs; in terms of laser perception, a full semantic segmentation model is used to effectively improve the perception performance in severe weather such as rain, fog, snow, sand and dust; in addition, MOT multi-target tracking has been implemented in multiple projects, which can greatly improve the stability of fused perception. sex.

With its industry-leading full-stack self-developed smart driving technology and industrial chain resource advantages, Youdao Zhitu has made substantial breakthroughs in several mainstream application scenarios such as ports, mining areas, trunk logistics, and sanitation buses, and continues to use Autonomous driving technology leads the commercial development of the industry, accelerates the iteration of autonomous driving technology, and achieves "unmanned" social roads in specific scenarios, providing a typical case for large-scale promotion across the country. So far, youdao Zhitu has accumulated nearly 7 million autonomous driving operation miles in implementation scenarios, completed more than 320,000 TEU real-world transshipment tasks, and initially realized the commercial ecological layout of autonomous driving in all fields and business chains.

At the end of the sharing, Lai Jie also said that Youdao Zhitu is exploring BEV sensing technology. BEV (Bird's Eye View) refers to a bird's-eye perspective or coordinate system that can three-dimensionally describe the perceived real world. It is equivalent to looking down at the vehicle and the surrounding environment from 10-20 meters directly above the vehicle. It is also called "God's perspective". The BEV-based Occupancy grid can provide a three-dimensional description of the driving scene, especially the three-dimensional construction of long-tail problems in autonomous driving, such as special-shaped vehicles and universal obstacles, to further improve the vehicle's ability to understand the environment. And through the dynamic and static estimation of each occupied grid, it can improve the effective prediction of the behavior of traffic participants and improve the safety level of autonomous driving. Youdao Zhitu has invested a lot of R&D resources in BEV sensing, including building a BEV cross-modal unified data set, BEV pre-fusion algorithm development, BEV visual 3D target detection, BEV visual 3D lane line detection, BEV Occupancy grid, etc., to further strengthen Improve the accuracy and safety of autonomous driving system perception.
