Introduction

China Telecom has constructed the national "1+31+X" framework comprising one network, one cloud, one platform, and one real-time visual twin map as the base for the Vision Twin system across the entire region. By integrating the Xingchen Haina visual large model, it activates the value of video data elements, overcoming challenges such as dispersed video locations, fragmented footage, and data silos, which leads to the large-scale application of Vision Twin technology in China.

Four Technological Breakthroughs Empower the Transformation of Vision Twin Business Models

This project represents another significant breakthrough and innovation in China's Vision Network industry. Centred around the Vision Twin engine, it employs real-time, all-encompassing multi-scenario video fusion algorithm innovations to achieve video correction and perspective transformation, restoring spatial structure information and constructing a three-dimensional real-world environment, thereby addressing fragmented videos and unclear content issues. Utilising the Xingchen Haina large model as the foundational LO layer, it innovates on keyframe labeling algorithms to achieve automatic and precise scene understanding and semantic labeling of keyframes across 70 million video terminals, seamlessly integrating elements such as people. vehicles, and objects in dynamic scenes. This greatly enhances the capably for semantic understanding of video content and resolves challenges related to large volumes of video data, diverse types, low-value density, and slow response times for scene-based applications. Supported by China Telecom's extensive Tianyi Vision Network, the project innovates in large-scale video data transmission technologies to enable collaborative resource synergy. A scenario-based model and the Vision Twin inside innovative approach empower many industries with high-quality, large-scale solutions.

Reinventing Thousands of Industries, Applications at Scale, and Extreme Performance

This project centres on the Vision Twin Engine, powered by large model capabilities to create a product system for comprehensive spatial-temporal perception, analysis, prediction, and control of all spatial elements, achieving significant economic and social benefits. Over the past three years, the project has generated nearly 10 billion yuan in direct product revenue, with over 1.5 billion yuan in 2021, over 3.5 billion yuan in 2022, and over 4.59 billion yuan in 2023. As of May 2024, the project has attracted 98 million Vision Network users covering 360,000 administrative villages and 160,000 communities nationwide. It provides a foundational platform for Vision Twin and over 7 million innovative industry applications, it offers end-to-end Vision Twin service capabilities for vertical industry innovation and scalable development, directly driving the industry chain's output value by over 30 billion yuan. China Telecom has initiated the establishment of the Vision Baichuan Ecological Alliance building a community for Vision Twin applications, contributing to the construction of a real-time, realistic digital China, and playing a significant role in promoting the high-quality development of the digital economy and society.

Building a Collaborative Ecosystem for Vision Across All Domains

As a pioneer in Vision Network, China Telecom adheres to a customer-centric approach, building a comprehensive ecological collaboration system to promote the transformation and large-scale development of Vision Twin technology innovation achievements. It has led or participated in formulating over 20 international standards, including establishing the ITU-T SG16 "Video Surveillance Services and Systems," It is responsible for organising and advancing research on video surveillance series standards, maintaining the standardisation roadmap, and coordinating certification testing. China Telecom also led the establishment of expert groups for ISO/EC JTC1 SC29 VCM and SAC TC28 SC29 DCM, shaping a forward-looking influence in cutting-edge technology. Based on its research achievements, the project has prominently released the "China Telecom Vision Network Cloud Technology White Paper," filed over 40 invention patents and more than 60 software copyrights, and linked patent standards to drive the transformation of innovation results, Related achievements have received significant awards, including the "Third Prize for Science and Technology from the China Communications Society," the "Second Prize for Technological Progress from China Telecom 2022," and the "Outstanding Scientific and Technological Achievement at the 2023 Digital Expo."
