A platform on real-scene 3D modeling of the city of Qingdao was launched in March 2021 under the leadership of the Qingdao Institute of Survey and Mapping

Qingdao’s varied topography – marked by hilly terrain and dramatic elevation changes – necessitated the use of oblique aerial imaging to capture raw imagery and build an accurate 3D model. The project team deployed manned fixed-wing aircraft equipped with 150-megapixel, five-lens oblique aerial cameras. The aerial survey covered the entire urban area, achieving a ground resolution of 15 centimeters and maintaining more than 70 percent image overlap to maximize accuracy.

In March 2022, following expert review, the project was officially launched for citywide application. Today, the platform covers Qingdao’s entire land area – 11,000 square kilometers – as well as 800 kilometers of coastline, 49 bays, and seven inhabited islands.

The 3D simulation platform has been shared with over 60 municipal departments. It supports more than 100 key functions, including disaster prevention and mitigation, urban planning, social governance, and urban renewal. The platform also underpins over 70 digital government service applications and records nearly 100 million uses annually. As an example, at the bureau’s headquarters, staff members examined two versions of a digital model for a former mining site in Qingdao’s West Coast New Area. The comparison revealed tangible signs of ecological restoration – more vegetation and a gentler slope. Qingdao is home to 898 legacy mine sites. In the past, inspecting these sites required a full month of on-the-ground efforts. Now, with the help of the 3D model, the same work takes just five days.

Since 2023, the city has carried out annual temporal updates to the city-scale 3D simulation platform, enabling it to track urban changes with precision and support data-driven lysis and evidence-based planning.

A 150,000-tonne deep-sea intelligent aquaculture vessel was delivered for use in Qingdao. The ship is 244.9 meters long and houses 15 breeding cabins with a total water holding capacity of nearly 100,000 cubic meters.

The ship-borne smart aquaculture system is expected to have an annual output of 3,600 tonnes of high-quality fish. The breeding cabins can be used to cultivate fish species such as large yellow croaker and salmon.

The new aquaculture vessel is an updated version of its 100,000-tonne predecessor delivered in 2022. Its predecessor has now already traveled over 17,000 nautical miles. The vessel pushed the aquaculture area from nearshore to deep sea, using high-quality seawater resources for breeding.

During the Chinese New Year holiday, a mountain climbing support robot jointly developed by Taishan Wenlun Group and Shenzhen Kenqi Technology Co. was test-introduced in the Taishan Scenic Area. Guangming reported.

According to Taishan Wenlun Group, the mountain climbing support robot can be used in a wide range of areas in daily life and work, such as mountain climbing, fitness, running, walking, and climbing up and down stairs. It weighs just 1.8 kilograms and is ergonomically designed with power, electronics and artificial intelligence (AI) algorithms. It can sense every movement of the lower limbs and provide support at the right time.

According to the group, it can operate continuously for more than five hours.  The product is currently in the trial operation phase, and the company plans to launch 200 units on the market in early March.
