00:02:14, and the cultural relics of the great Chinese emperors are like stars
00:02:18in alignment
00:02:19.
00:02:23The history of ministers awaits awakening ,
00:02:27and modern measurement technology is subtly integrated . It has created a complete
00:02:31support system for archaeological
00:02:34work
00:02:37.
00:02:40It breaks the limitations of traditional exploration methods and protection measures
00:02:44. It uses satellite rods, laser radar and other
00:02:48technologies to explore the earth .
00:02:51。
00:02:53Through the construction of three-dimensional models of stone scenes , a permanent digital
00:02:57archive has been established. This not only promotes
00:03:01archaeology from traditional manual operations to digitalization and
00:03:05intelligence, but also provides scientific and precise
00:03:09system technical support for building the Chinese
00:03:12civilization standard system , becoming a national treasure
00:03:16for guarding and inheriting history
00:03:30. In November, Jiangnan Fanqiu and his team were walking through a bamboo forest
00:03:34.
00:04:04The two main ancient cities have been identified , dating back approximately 5,000 to 4,000
00:04:08years ago, belonging to the late Neolithic period cultural sites
00:04:11, concentrated in the lower reaches of the Yangtze River and Taihu Lake basin
00:04:15. They are examples of early urban civilization
00:04:19and a key period in the 5,000-year history of Chinese civilization
00:04:23. To further identify the evidence chain
00:04:27of the origin of civilization , at present
00:06:19, as early as 2009 , Yao Gan technology began to participate
00:06:23in the archaeological excavation of the two ancient cities and their surrounding areas
00:06:26. Archaeologists compared satellite images from different
00:06:30historical periods to trace the natural evolution of ancient
00:06:34sites on the ground , locate existing
00:06:37points of interest , and then verify them through field
00:06:41archaeological drilling to finally
00:07:48.
00:07:53This cannot be natural because natural things don't look like this.
00:07:57This is also consistent with the characteristics of water.
00:08:02With the "heavenly eye" provided by Huawei, the efficiency of the corner-to-corner has undergone earth-shattering changes.
00:08:42Well, let me mark this first . It's that on the west side
00:08:46of our ... there's a broken half
00:08:50. In the past , when we stood on the ground
00:08:54, uh, stood on high ground, your field of vision was very small. We
00:08:58have basically collected all these early satellite images of the entire
00:09:01Zhejiang Province, and even the Yangtze River Delta . You can find a lot
00:09:05of things. So you view this instrument as a city
00:09:09, a metropolis .
00:10:18Today, we are mainly focusing on the area around the venue, including the wall
00:10:22. Pay attention to the gate .
00:11:29The Beijing central axis first appeared in the 13th century, extending
00:11:32from the Bell and Drum Tower in the north to Yongding Gate in the south, with a total length of
00:11:367.8 kilometers . It is the central symbol
00:11:39of ancient Beijing . The unique magnificent order
00:11:42of Beijing originated from this
00:11:46. To comprehensively display such an ancient building complex
00:11:50that is deeply intertwined with modern cities, and to allow people to see it clearly
00:11:54and in detail , the three-dimensional
00:11:57modeling of stone scenes has become an indispensable technical means
00:12:00.
00:12:04The three-dimensional axis of the stone well actually preserves
00:12:07the central axis in a three-dimensional
00:12:11form. So, on the one hand, it
00:12:15provides us with a precise spatial data base
00:12:19for the protection and monitoring of the entire central axis. On the other hand, it also leaves
00:12:22a valuable data asset for our future generations. We have established
00:12:26a central axis cultural heritage protection and monitoring platform based on this technology. This platform
00:12:30is a fixed indicator of the central axis's deep
00:12:34meaning.
00:12:37In September 2020 , the Beijing Institute of Surveying and Mapping organized a
00:12:40technical team of more than 200 people to conduct on-site surveying
00:12:44and mapping of the Temple of Heaven and other central axis cultural heritage sites
00:12:48. This was the first large-scale surveying and mapping work
00:12:52ever conducted on the central axis cultural heritage sites
00:12:56. The central axis is located in the core area of the capital, and its airspace
00:12:59is strictly restricted . Therefore, we cannot
00:13:03use conventional low-altitude oblique photography and other methods
00:13:07. So we adopted a full ground scanning method
00:13:10.
00:13:11。
00:13:20In different situations, we will use different 3D scanners. This
00:13:24is.
00:13:55This is our mobile backpack 3D scanner
00:13:58. It can be carried on the back of our survey personnel
00:14:02and move with the person for mobile scanning
00:14:05. The advantage of this is that it is relatively flexible
00:14:09and the scanning speed is very fast
00:14:11.
00:14:17We also have a handheld device, which is very
00:14:21compact and lightweight . For example, we
00:14:58are basically recreating a physical world's Temple of Heaven on the computer
00:15:00.
00:15:06For the protection of the main building, our precise measurements can
00:15:09detect every tiny displacement
00:15:13and see some very small
00:15:16damages. So , by comparing
00:15:20two periods of data, we can find the damaged parts
00:15:24of the cultural relic. So, this is also a very important role of our
00:15:28surveying and mapping technology in cultural relic protection and restoration. Our
00:15:32work received unanimous praise from international experts
00:15:35during the review. It can be said that it directly supported
00:15:39the successful bid of the central axis .
00:15:43In 2024, the Beijing Central Axis, the rhythm of China's ideal
00:15:47city system, was successfully listed in the World Heritage List
00:15:50. The 12-year journey of profound significance was brought
00:15:54to a successful conclusion with the support of surveying and mapping technology. This
00:15:58treasure of Chinese culture has gained worldwide recognition and
00:16:01attention. After the successful application, the three-dimensional
00:16:05technology of the stone well continues to be used
00:17:07. New technology helps preserve the ancient charm and promotes the systematic protection of cultural
00:17:11heritage, inheriting cultural traditions and extending them across mountains
00:17:15and seas, ensuring their lasting
00:17:17existence
00:17:24. Shanxi, one of the birthplaces of the Chinese nation, has a recorded
00:17:28history of more than 3,000 years
00:17:31. Ancient relics from various historical periods are scattered
00:17:35throughout the mountains
00:17:38. To survey and maintain these ancient buildings
00:17:42located on steep cliffs , traditional scanning
00:17:46methods can hardly achieve comprehensive data acquisition
00:17:49. Drone aerial scanning has become the best
00:17:53method under new technological
00:18:01conditions. This should be evenly distributed in the car area, several of them. It's best
00:18:04to be in an open space , not easy
00:18:10. I started in 2005 doing ground-based geological
00:18:13measurements. Then in 2006 , I switched to manned aerial
00:18:17photography. It wasn't until 2018 that I switched to
00:18:21drones. There's a saying, "For historical artifacts on the ground, look to Shanxi
00:18:25."
00:20:1230 meters. You need to get the angle right
00:20:15.
00:20:23With drone scanning technology , ancient buildings on cliffs
00:20:27can be displayed in 360 degrees without blind spots
00:20:30. Many ancient
00:20:34sword artifacts scattered throughout Shanxi Province , with the assistance of surveying and mapping technology
00:20:38, are no longer hidden in deep mountains and unknown
00:20:42. Shanxi's cultural relics have a special feature: there are many cultural relics,
00:20:46especially ancient architectural cultural relics, but they are scattered in many areas.
00:21:22It's hard to find a control point here . Let's find
00:21:25a control point
00:21:26.
00:21:35As of November 2025 , the Shanxi Provincial Surveying and Mapping
00:21:38and Geographic Information Institute has completed the production of fine 3D models
00:21:42for all prefecture-level city built-up areas in the province. Among them,
00:21:46370 national and provincial-level cultural relic protection units
00:21:50are included
00:21:50. For Shanxi Province, with 53,875 immovable cultural relics
00:21:58everything is just beginning
00:22:01. There are many cultural relics in the mountains, and many of them have not been discovered
00:22:12. We will survey those undiscovered places
00:22:16.
00:22:22We surveyors have a saying, "Measure the earth with your feet
00:22:26." So, we walk where others haven't
00:22:49. Every Monday, Huang Xianfeng and his colleagues
00:22:53come to the studio early
00:22:55.
00:22:57Massive amounts of digital data of ancient buildings are gathered here, awaiting
00:23:01further processing
00:23:02.
00:23:06Huang Xianfeng's team is currently working on the three-dimensional modeling
00:23:10project of the ancient building complex of Wudang Mountain in Hubei
00:23:13.
00:23:16As a World Cultural Heritage site, the Wudang Mountain ancient building area
00:23:50. Now the entire data processing has reached 90%, 98%
00:23:54has been completed .
00:23:57We .
00:24:00First, we take photos , more comprehensive photos
00:24:04of the object we need to model . Then the second step is to locate
00:24:08the photos to the position where they were taken. Each
00:24:11point is a photo. In this project , I have more than 28,000
00:24:15photos .
00:24:19Then there are
00:24:221.24 million points connected
00:24:26. The third step is our core key technology, which is to automatically generate models from these photos and their positions through master processing. This means that through the photos I just showed, you can see that the
00:24:44clarity is very high, like the cracks inside
00:25:54. In the second year after 2007, the technology I studied was the combination of laser scanning technology
00:26:02. So it was at that time that I started to get in touch with this speed
00:26:06.
00:26:08No matter what kind of cultural relic it is, it is a combination of substances. No matter whether it's
00:26:12paint or solid material , it will definitely degrade. Ultimately, no
00:26:16matter how you protect it, it can only slow down, not guarantee that it
00:26:20will exist forever. So I hope to record it through digital means. We use digital
00:26:24technology to make cultural relics immortal in the digital space
00:26:26. In 2009
00:26:30, after two years of arduous exploration
00:26:32, Huang Xianfeng and the Dunhuang Research Institute's Cultural Relics Digitalization
00:26:36Research Institute gradually improved projection measurement and model construction
00:26:40, and finally overcame the technical difficulties of high-quality mapping of cultural relics
00:26:44, achieving ultra-high-quality 3D reconstruction of the Dunhuang Grottoes. The breakthrough
00:26:48in this technology also provides important technical means
00:26:52for the digitalization of immovable cultural relics and the digital protection of museum
00:26:56collections nationwide
00:26:57.
00:28:34My dream is actually that I hope our technology can truly
00:28:38be used by every cultural relic unit
00:28:41, so that our cultural relics can quickly enter the digital
00:28:45space , and people can use it. To make
00:28:48usable technology, to create new technology for the world
00:28:52and for experts . Not to repeat other people's technology
00:28:56. Technology is indeed updating very fast
00:28:59. In the future , I think it will
00:29:32automatically start 360-degree scanning and automatic
00:29:36recording .
00:29:39Our scientific and technological archaeology in China has developed very well
00:29:43. We can try to solve our own problems
00:29:46, and can we also export and solve
00:29:50world problems? I think I am quite confident that we can try
00:29:54it
00:29:55.
00:30:06Surveying and mapping technology protects the memory of Chinese civilization, breaking through
00:30:10the barriers of time, allowing buried cultural relics to see the light of day
00:30:13, making ancient buildings last forever
00:30:17, and injecting scientific and technological power into cultural relic protection
00:30:20. Today, surveying and mapping geographic
00:30:24information technology is using precise coordinates and intelligent
00:30:28data to bring cultural heritage spanning thousands of years to life
00:30:32. In the future, technology will transcend regional and temporal limitations
00:30:36, promoting the archaeological and cultural undertakings
00:30:40in China's great process of modernization to a broader world
00:30:43.
00:30:46The rebirth of ancient artifacts is not only the restoration of buildings, but also the continuation of civilizational
00:30:50memory. It is not only a victory of technology, but also the inheritance
00:30:53of wisdom
00:30:54.
00:31:03The more you measure, the more you serve , the further you go
00:31:06.
00:31:09The beginning of fate , begins
00:31:12with the soft fullness of childhood .
00:31:16Gazing at the parents' eyes by the crib
00:31:19,
00:31:22the fate of childhood, chasing the moonlight scattered by the window
00:31:26,
00:31:28is the sweet touch
00:31:31between the lips
00:31:35. The fate of growth is the school bell
00:31:39ringing
00:31:41in the classroom
00:32:20. That ring. It's the distant full moon seen together from the new home's window
00:32:24.
00:32:27In life's many aspects , complete peace of mind
00:32:30.
00:32:36Celebrate reunion with joy
00:32:39.
