iOS 11 introduces ARKit, a new framework that allows you to easily create unparalleled augmented reality experiences for iPhone and iPad. By blending digital objects and information with the environment around you, ARKit takes apps beyond the screen, freeing them to interact with the real world in entirely new ways.
iOS 11 引入了 ARKit，这是一个全新的框架，允许开发者轻松地为 iPhone 和 iPad 创建无与伦比的增强现实体验。通过将虚拟对象和虚拟信息同用户周围的环境相互融合，ARKit 使得应用跳出屏幕的限制，让它们能够以全新的方式与现实世界进行交互。

ARKit uses Visual Inertial Odometry (VIO) to accurately track the world around it. VIO fuses camera sensor data with CoreMotion data. These two inputs allow the device to sense how it moves within a room with a high degree of accuracy, and without any additional calibration.
ARKit 使用视觉惯性里程计 (Visual Inertial Odometry, VIO) 来精准追踪周围的世界。VIO 将摄像头的传感器数据同 Core Motion 数据进行融合。这两种数据允许设备能够高精度地感测设备在房间内的动作，而且无需额外校准。

With ARKit, iPhone and iPad can analyze the scene presented by the camera view and find horizontal planes in the room. ARKit can detect horizontal planes like tables and floors, and can track and place objects on smaller feature points as well. ARKit also makes use of the camera sensor to estimate the total amount of light available in a scene and applies the correct amount of lighting to virtual objects.
借助 ARKit，iPhone 和 iPad 可以分析相机界面中所呈现的场景，并在房间当中寻找水平面。ARKit 不仅可以检测诸如桌子和地板之类的水平面，还可以在较小特征点 (feature points) 上追踪和放置对象。ARKit 还利用摄像头传感器来估算场景当中的可见光总亮度，并为虚拟对象添加符合环境照明量的光量。

ARKit runs on the Apple A9 and A10 processors. These processors deliver breakthrough performance that enables fast scene understanding and lets you build detailed and compelling virtual content on top of real-world scenes. You can take advantage of the optimizations for ARKit in Metal, SceneKit, and third-party tools like Unity and Unreal Engine.
ARKit 运行在 Apple A9 和 A10 处理器上。这些处理器能够为 ARKit 提供突破性的性能，从而可以实现快速场景识别，并且还可以让您基于现实世界场景，来构建详细并引人注目的虚拟内容。您可以利用 Metal、Scenekit 以及诸如 Unity、虚幻引擎之类的第三方工具，来对 ARKit 进行优化。
