全國測繪法宣傳日 | “實景三維中國”建設：智“繪”立體中國
在大熊貓國家公園，“滾滾”們正享受著360°無死角的保護。隨著實景三維技術不斷發展，數字孿生平臺、“天空地”一體化監測體系、大熊貓保護5G消息應用、AI“熊貓臉”識別等線上系統相繼誕生，正努力為大熊貓及其8000多種伴生動植物打造更加安全舒適的“智慧新家”。
In the Giant Panda National Parkin west China, the pandas are enjoying 360-degree protection. The continuous development of 3D real-scene technologies has led to the emergence of digital twin platforms, integrated monitoring systems covering the space from sky to ground, 5G messaging applications for panda conservation, and AI-based “panda face” recognition systems. Combined efforts are being made to create a safer and more comfortable “smart home” for the giant pandas and the more than 8,000 associated plant and animal species.
大熊貓的“智慧新家”離不開地理資訊的精確採集與處理技術的發展。2022年，中國全面開展“實景三維中國”建設，主要包括五個維度：地形級、城市級、部件級的實景三維建設，以及物聯感知數據接入與融合、線上系統與支撐環境建設。
The creation of the giant pandas’ “smart home”relies on the development of precise geographic information collection and processing technologies. In 2022, China has launched the comprehensive development of “3D Real-Scene China.” This initiative encompasses five dimensions: the development of 3D real scene at the terrain level, urban level, and component level, as well as the integration of Internet of Things (IoT) sensing data and the development of online systems and supporting environments.
固有“天府之國”之稱的四川省為打造更高水準的“天府糧倉”，以3釐米傾斜攝影生産的實景三維模型為“骨架”，利用其“所見即所得”的特點，構建電子柵欄，實現對耕地的智慧化、無人化“看護”。2023年，成都平原7500平方千米的區域已被實景三維模型全部覆蓋。
Southwest China’s Sichuan Province, known as the land of abundance, is striving to create a more advanced major granary of the country. Using 3D real-scene models produced through 3cm-precision oblique photography as the “skeleton,” the province is leveraging its “true-to-life” feature to build an electronic fence, enabling intelligent and unmanned guarding of cultivated land. By 2023, an area of 7,500 square kilometersof the Chengdu Plainhad been fully covered by 3D real-scene models.
目前，中國共計26個省（區、市）的264個城市已開展實景三維模型建設，在不久的將來，政府決策、生産調度和生活規劃均可通過線上實景三維空間完成。
Currently, a total of 264 cities in 26 provincial-level regions in China are developing 3D real-scene models. In the near future, government decision-making, production scheduling, and urban planning can all be facilitated through online 3D real scenes.
湖南張家界作為電影《阿凡達》異世界的原型，地形地貌複雜險峻。通過對景區進行高精度三維建模，不僅用數字化的方式呈現出了張家界的“一草一木”，更識別出多處存在風險的危岩體，為地質監測和災害防治提供了重要依據。一個個核心景區和場館的三維模型構成的VR地圖，帶遊客“雲”遊張家界，並提供各類服務。
As the prototype of the alien world in the movie “Avatar,” Zhangjiajie in central China’s Hunan Province boasts a complex and rugged terrain. Through high-precision 3D modeling of the scenic area, not only has the digital representation of the natural environment in Zhangjiajie been realized, but also multiple risky rock formations have been identified, providing important basis for geological monitoring and disaster prevention. A VR map composed of 3D models of core scenic areas and venues allows tourists to virtually explore Zhangjiajie and provides various services.
實景三維能在“復刻”現實世界的同時，接入空間位置、網際網路等物聯感知數據，實現數字空間與現實空間的實時關聯互通，並通過數據融合與共用，為數字政府、數字經濟發展提供重要的數據資源，是數字中國建設的“立體藍圖”。
3D real-scene technology not only replicates the real world but also integrates spatial positioning and IoT data, enabling real-time correlation and interaction between digital and physical spaces. By harnessing data fusion and sharing, it provides valuable data resources for the development of digital government and digital economy, thus serving as a three-dimensional blueprint for the development of Digital China.
在第21個“全國測繪法宣傳日”到來之際，中國聚焦於世界新一輪技術革命浪潮，實景三維中國建設，助力地理測繪行業邁向更加智慧、高效的新紀元。
On the occasion of the 21st National Surveying and Mapping Law Promotion Day, China is riding on the global wave of the new technological revolution with the development of the 3D Real-Scene China initiative, which is poised to propel the geospatial surveying and mapping industry into a new era ofelevated intelligence and efficiency.
