Augmented reality is a powerful way to bring the physical and digital worlds together. AR places digital objects and useful information into the real world around us, which creates a huge opportunity to make our phones more intuitive, more helpful and a whole lot more fun.
增强现实是将物理和数字世界结合在一起的强大方式。AR把数字对象和有用的信息放到我们周围的真实世界中，这创造了一个巨大的机会，让我们的手机更直观，更有帮助，更有趣
We’ve been working on augmented reality since 2014, with our earliest investments in Project Tango. We’ve taken everything we learned from that to build ARCore, which launched in preview earlier this year. Whereas Tango required special hardware, ARCore is a fast, performant, Android-scale SDK that enables high-quality augmented reality across millions of qualified mobile devices.
自2014年以来，我们一直在研究增强现实技术，我们最早的投资项目是Tango项目。我们已经把从那学到的一切东西都用来构建ARCore，它在今年早些时候发布了。Tango需要特殊的硬件，ARCore是一款快速、高性能、android级的SDK，它能让数百万合格的移动设备实现高质量的增强现实。
Developers can experiment with ARCore now, and we’ve seen some amazing creations from the community. ARCore also powers AR Stickers on the Pixel camera, which launched earlier this week and lets you add interactive AR characters and playful emojis directly into photos and videos to bring your favorite stories to life.
开发者现在可以用ARCore做实验，我们已经看到了来自社区的一些令人惊奇的创作。ARCore还为像素相机提供了AR贴纸，这款相机于本周早些时候发布，让你在照片和视频中直接添加互动的AR字符和好玩的表情符号，将你最喜欢的故事带到生活中。
Today, we’re releasing an update to our ARCore Developer Preview with several technical improvements to the SDK, including:• A new C API for use with the Android NDK that complements our existing Java, Unity, and Unreal SDKs;• Functionality that lets AR apps pause and resume AR sessions, for example to let a user return to an AR app after taking a phone call;• Improved accuracy and runtime efficiency across our anchor, plane finding, and point cloud APIs.今天，我们将向我们的ARCore开发者预览版发布更新，并对SDK进行几项技术改进，包括:• 一个新的C API用于Android NDK，它补充了我们现有的Java、Unity和Unreal sdk;• 让AR应用程序暂停和恢复AR会话的功能，例如让用户在接到电话后返回AR应用程序;通过我们的锚点、平面发现和点云api提高了精度和运行时效率。

As we focus on bringing augmented reality to the entire Android ecosystem with ARCore, we’re turning down support of Tango. Thank you to our incredible community of developers who made such progress with Tango over the last three years. We look forward to continuing the journey with you on ARCore.
当我们专注于用ARCore将增强现实技术引入整个Android生态系统时，我们拒绝了Tango的支持。感谢我们不可思议的开发者社区，他们在过去的三年里取得了进步。我们期待着继续与您在ARCore的旅程
If you’re a developer interested in AR, now's the time to start experimenting. In the coming months, we’ll launch ARCore v1.0, with support for over 100 million devices. And soon, many augmented reality experiences will be available in the Play Store. We can’t wait to see what you create.
如果你是一个对AR感兴趣的开发者，现在是开始尝试的时候了。在接下来的几个月里，我们将推出ARCore v1.0，支持超过1亿的设备。很快，许多增强现实体验将在游戏商店中出现。我们迫不及待地想看看你创造了什么。
