The "black technologies" of Hangzhou Asian Games include: live-action holographic live kiosks, fire patrol robots, intelligent seal cutting platforms, intelligent fresh food machines and so on.

1. Live-action holographic kiosk

Based on the theory of computational imaging of camera array light field, this technology can acquire, reconstruct and render real-world light field, and realize 3D image recording of human body and real-time live-action holographic communication. Athletes, spectators and tourists will be able to roam in different reconstruction scenes and enjoy the unprecedented "3D impression of Hangzhou Asian Games" and real-time holographic experience.

2. Fire patrol robots

These robots will be used in the daily fire prevention and control of various social fire prevention key units during the Asian Games. Using high-definition cameras and infrared thermal imagers, robots can patrol all kinds of buildings, environments and fire-fighting facilities around the clock through artificial intelligence, Internet of Things, big data and 5G communication technologies. The inspection data will also be transmitted to the fire control room synchronously, which will be linked with the security and fire control system to improve the safety level of key units.

3. Intelligent seal cutting platform

In order to better promote the traditional culture of China, the platform system will be stationed in the cultural hut and golf hall of the Asian Games Village. By uploading photos or inputting English, users can produce corresponding seals, which solves the problem that foreign athletes and tourists don't know Chinese characters.

4. Intelligent fresh food machine

With the intelligent fresh food machine, users only need to select the food in the applet, place an order and pay for it, and then they can enjoy the freshly cooked food after waiting for 2 minutes. Using 3D intelligent cooking technology, fresh dishes refrigerated in the machine can be cooked quickly.

The idea of hosting the Hangzhou Asian Games:

1. Intelligence

In terms of "intelligence", the Hangzhou Asian Games fully demonstrated the characteristics of Hangzhou. Smart poles are equipped around each venue, and the interior of the venue is covered with 5G systems, new energy charging piles, Internet of Things equipment and a visual venue operation and maintenance platform.

2. Green

In terms of "green", the Hangzhou Asian Games has formulated a series of green environmental protection standards, covering green buildings, healthy buildings and indoor environmental control.

3. Thrift

In terms of "frugality", of the 57 competition venues for the Hangzhou Asian Games and the Asian Para Games, only 12 were newly built, accounting for only 21%, and the rest were rebuilt. This is a relatively low proportion in previous Asian Games, which embodies the principle of thrifty hosting.

4. Civilization

In terms of "civilization", the Asian Games venues have created a humanized barrier-free environment, which is designed according to the standard of "leading in China and first-class in the world", demonstrating the inclusiveness and humanistic care of the city.
