First, Li Jiaqiweiya brought goods through Taobao live broadcast, and then there is the "Cloud Spring Tour" on the museum website. Land live broadcast has never lacked lively themes and technical thresholds, while underwater live broadcast has always been a lot of people due to the limitations of technology and environmental conditions." Unreachable” live broadcast field.

The emergence of underwater drones will undoubtedly make the "impossible" possible. The functions of the deepest dive of 100 meters and the real-time transmission of video signals break through the problem of underwater live broadcast. I believe that there will be more underwater live broadcast booms in the future. In-depth exploration will appear in the hot topic of underwater live broadcast in the future.

On the afternoon of April 16, Baidu APP Earth Roaming Program and China's non-profit organization Wujing Deep Blue launched the first underwater in-depth live broadcast of the entire network in Qiandao Lake, Chun'an County, Zhejiang Province.

The ancient cities explored this time are all underwater at a depth of 30 meters. They are in Chun'an County, Zhejiang Province. The ancient city has a history of more than a thousand years. In 1959, due to the construction of the Xin'an River Hydropower Station to intercept and store water, the two ancient cities of Hecheng and Shicheng "sinked". "Underwater.

After more than 60 years, what kind of changes have the ancient villages undergone? Baidu Earth Roaming Program revealed this historic underwater ancient city to 2.32 million viewers online through the footage of the Youcan underwater drone. The signal during the entire live broadcast was stable and smooth, and the 5-hour long battery life also provided time guarantee for the live broadcast. . Although there is not enough light in the deep water, the outline and style of the old house are still clearly visible. The reasons for the sinking of the ancient city and the story behind the owner of the ancient house have aroused the curiosity of netizens.

In 2001, the tourism department of Chun'an County cooperated with diving agencies to dive into the bottom of Qiandao Lake to detect the specific location of the ancient city, and planned to develop the underwater Qiandao Lake into an underwater tourism project, but due to the difficulty, it has not yet been realized. The underwater ancient city of Qiandao Lake has also become the exclusive image data of many historians and divers. It is difficult for the public to have a chance to see the underwater ancient city. This time, Baidu APP brought many netizens to popularize this ancient city with great historical and cultural value through the form of Youcan underwater drone live broadcast.

Why is water green

Many friends watching the live broadcast said that the color of the lake is very green, why is this?

This is because the depth of the river water is relatively shallow, which is not enough to absorb the green light, and the river water contains microorganisms, algae, and particulate matter, etc., which can easily make the lake appear green, and the color will change subtly after 5 meters underwater. The depth of the water is deeper, which can absorb green and reflect blue. The underwater footage of the drone can clearly see the particles suspended underwater.

The BW Space Pro underwater drone is equipped with a 4K high-definition front camera (resolution 3840x2160), which can record 4K high-definition video and 12-megapixel photos, but to ensure the stability of the live video signal, the live broadcast team captures 720P real-time Streaming video (1280x720 resolution), not the highest quality for underwater drone cameras.

Are there tombs underwater?

In the ancient lion city, there are indeed a large number of ancient tombs. In 2001, archaeologists accidentally discovered an ancient tomb while conducting archaeological activities underwater in Qiandao Lake, but the location of this underwater exploration is an underwater ancient house. Not tombs. Through the lens of the drone, we can see that the wooden beams, stairs and brick walls of the houses are still standing, and the carvings and large arches on the towers of many houses are clearly visible, showing a typical Huizhou architectural style.
