After the year before, Google officially announced the Augmented Reality Platform ARCore, saying that in the future, 100 million Android devices will experience interesting AR features.

Last year, ARCore launched the Cloud Anchors feature, allowing multiple people to play AR together, even if you and your sister are not the same phone Can also have the same 3D image.

Now, Google has opened a new step on the road to AR a>: Let the AR content you draw, stay in the real world for a long time.

This is a type of “persistent cloud anchors” new features that allow you to press the “Save” button to leave your own AR items, no matter how space or time changes in your position, you can see the overlay when you look back. Digital content above the real world.

Speaking of this, we will first introduce Google’s cloud anchor tool.

This tool is to enable people to draw virtual anchor points in real space through the device, and the latitude and longitude of these anchor points can be uploaded to the cloud, and users in the same environment can add cloud anchor points to their own devices. Then watch and interact with the AR image created at the anchor point.

Now Google has updated the cloud anchor system, and developers are improving the visualization of cloud anchors and their location databases.

People can create larger areas and more angled 3D images in the field scene. After creating the image, the visual data will be deleted. Only the anchor ID can be shared, and other objects can participate through the anchor ID. .

This will be a new experience for people like Google Augmented Reality Product Manager Christina Tong stated:

Imagine that you will be able to redesign your virtual space with others, leaving a whole year of memory;
You can draw AR notes for your friends around the amusement park, hide AR items in specific places around the world, and let people explore and discover.

Google says this is an important step in their future.

Because this is reflected”How AR pushes the limits of computer vision, how to cross the digital and physical world, and expands in our daily lives.”

Now, the first app that uses the “persistent cloud anchor” feature is Mark AR, and people can use this app and Other people in the public place generate and share AR content together and view and modify it over a long period of time.

In the future, Google also hopes to further develop “persistent cloud anchors” that will allow people to map and anchor content in a larger area and for a longer period of time, gradually bridging the digital and physical world.

However, technically, Google’s “persistent cloud anchor” is not a new idea.
