In the past two years, smart cars have been on fire. The core technology of smart cars and the selling point of autonomous driving technology have become the focus of efforts of major technology manufacturers.
Among them, the automatic driving technology in the direction of lidar should be regarded as the mainstream in China at present, after all, in addition to Tesla, other intelligent car companies have begun to install lidar on their own cars.
The automatic driving based on lidar actually requires the cooperation of high-precision maps, and it is impossible to achieve automatic driving without the location of high-precision maps, which is also one of the limitations of lidar technology.
Compared with ordinary maps, high-precision maps have higher positioning accuracy and richer data dimensions, and add a large amount of assisted driving related information.
Therefore, there are many manufacturers that have set their sights on high-precision maps, such as Huawei, AutoNavi, Baidu, Tencent, etc.
Recently, Huawei has gone a step further and officially released the group standard "General Technical Conditions for Road Intersection Traffic Information Holographic Collection System", which was jointly approved and jointly compiled by Beijing Tumeng Technology Co., Ltd., Beijing Chinasoft Zhengtong Information Technology Co., Ltd., Shenzhen Municipal Public Security Bureau Traffic Police Department, and Changzhou Municipal Public Security Bureau Traffic Police Detachment.
This also makes the new term "holographic intersection" enter everyone's vision. So what is a "holographic intersection"? Simply put, it is combined with high-precision maps to present holograms of intersections, and then accurately ensure smooth and safe traffic.
As shown in the figure below, all the images of the intersection can be seen clearly by each car, and this is not only captured by the camera, but also the data collected through the three layers of positioning layers of cameras, radar and lidar sensors.
And "holographic intersection" is a step further high-precision map, naturally for the automatic driving landing has a great help, just imagine, the future of autonomous driving cars, can be fully linked with the map, intersection, then can really do people do not have to care about the car, the car can drive itself.
Of course, to truly achieve full automatic driving, the road is still very long, but it is the continuous superposition of various technologies, and finally from the quantitative change caused by qualitative change, the future in the road construction, it will also be as lively as the car, only the road is repaired, in order to better sell the car.
