What is the employment prospect of three-dimensional visualization?

The application prospect of three-dimensional visualization technology lies in efficient and high-precision rendering modeling, which can not only restore all elements of the physical world in a digital scene, but also realize the communication between the digital world and the physical world by combining the processing and calculation of real-time data, and construct the digital twin of the physical world.

Three-dimensional visualization technology is one of the key foundations to realize urban twinning and industrial twinning.

Through GIS data disclosure and tilt photogrammetry, a three-dimensional digital model with high position accuracy, high geometric accuracy, strong texture authenticity, exquisite truth and strong visual impact is constructed. After structural and semantic processing, RayData realized the display of 3D scenes and models in different terminals through the powerful real-time 3D rendering technology of self-developed open source engine, and supported the visual expression of geographic data.

For example, in February, 2065438+2009, the East Line Project of Sino-Russian natural gas pipeline, which is known as the "century project", was officially put into operation and ventilated, and was warmly congratulated and highly praised by the heads of state of China and Russia. As the first "smart pipeline" model project in China, the "digital twins" were built in the pipeline project of the East China-Russia line, which realized the feasibility study, design, procurement and construction under the unified data standard. With the continuous enrichment of operational dynamic data, "digital twins" will grow together with the whole life cycle of the pipeline.

In order to better present the "digital twins" to the management operators, Guangqiyuan RayData and Tencent have "tailored" a set of visual interactive management system for them, which realizes real-time graphic visualization, scene and deep interaction of data based on real-time data rendering technology.

Through large-screen visualization, intelligent management and control technologies such as yard management, line management, process operation and equipment of the East China-Russia Line are comprehensively, centrally and dynamically displayed from the national territory, designated areas to designated key equipment. It can monitor the operation status of "digital twins" in all directions and in all periods, and provide accurate and real-time information data for the operation, maintenance and risk investigation of pipeline projects.

Obviously, digital twin technology is unlocking more intelligent forms in the era of Industry 4.0. For example, partners such as RayData of Guangqiyuan and Robotics X of Tencent Robotics Lab are working together to build industrial intelligent robots. It has core technologies such as self-help planning, remote real-life control and visual perception, and can complete tasks in a dangerous and complex environment.

By docking with the park safety monitoring system and combining AI robot intelligent identification and analysis technology, Guangqiyuan RayData chemical and robot product fusion system integrates many discrete monitoring data in the park and presents them in an interactive three-dimensional digital twin scene in real time.

Managers and operators can know the current hidden dangers and risk details of the park in real time on the system, and can also remotely control AI robots to perform tasks such as shooting, so as to improve the accuracy of judging the safety situation of the chemical park.

It is worth noting that the concept of digital twins is not only active in the manufacturing industry of Industry 4.0, but also appears more and more frequently in the field of smart cities.

With ICT (information, communication and technology) becoming the main kinetic energy for the development of smart cities, mobile communication, Internet, cloud computing, sensors, artificial intelligence and quantum communication have been widely used in smart cities. The technological development in the fields of global perception, digital simulation and deep learning is about to usher in a turning point, which makes the digital twin of cities emerge as the times require.

Nowadays, there are all kinds of sensors and cameras everywhere in the city. With the Internet of Things technology including 5G, the data collected by these terminals can be extracted more quickly.

In the digital twin cities, the operation status of infrastructure (water, electricity, gas, transportation, etc.). ) and municipal resources (police, medical care, fire protection, etc.). ) will be collected by sensors, cameras and digital subsystems and transmitted to the cloud through Internet of Things technologies including 5G.

In 20 19, Guangqiyuan RayData joined hands with Tencent and Shanghai Jing' an district government to build a fully connected, fully scene and fully intelligent "digital Jing' an", realizing the deep integration of different government departments, and innovating and reshaping the traditional management model, business model and operating rules.

"Jing 'an Government Brain" is a platform-based artificial intelligence center that centers around the three basic elements of a city: population, legal person and land, and combines the rich governance experience of the government with huge government data and social data. At present, it can provide five basic capabilities such as intelligent population prediction, intelligent planning, intelligent business, intelligent supervision and intelligent regional conditions, and has provided support for 23 application scenarios for 1 1 government departments.

For example, on the question of how to choose a vegetable market, which is related to people's livelihood, the government's brain is to combine the current development status of the region, comprehensively consider the nature and scale of the commercial complex within the scope, and recommend a suitable vegetable market location. Generally speaking, the government brain thinks that it is not suitable for the location of the vegetable market near the new residential area, but it will actively recommend it in the bustling old city.

The market law reflected behind it is that with the transformation of the old city of Jing 'an and the construction of large-scale commercial complexes, the space is getting less and less, and the rent is getting higher and higher, leaving little room for penetration of cheap food markets. Therefore, the government's brain analysis believes that the old city, which seems to be prosperous in business, is the area where Jing' an lacks the cheapest food market.

It is these accurate recommendations based on data analysis that can help government business managers to formulate the layout planning of convenience facilities such as smart micro-vegetable markets and mobile food stalls, and provide people's livelihood services in prosperous urban areas.

It can be seen that the core value of digital twins in the development and construction of smart cities lies in that it can fully establish the real-time connection between the physical world and the digital world, and then record, analyze and predict the changes of the running objects in the whole life cycle.
