Tango Concepts Tango 概念

Tango is a platform that uses computer vision to give devices theability to understand their position relative to the world around them. It’ssimilar to how you use your eyes to find your way to a room, and then to knowwhere you are in the room and where the floor, the walls, and objects aroundyou are. These physical relationships are an essential part of how we movethrough our daily lives. Tango gives mobile devices this kind ofunderstanding by using three core technologies: Motion Tracking, Area Learning,and Depth Perception.

Tango是一个使用计算机视觉的平台，让设备能够了解他们相对于周围世界的位置。它类似于你如何使用你的眼睛找到你的房间的方式，然后知道你在房间里的地方，墙壁和你周围的对象在哪里。这些身体关系是我们如何在我们的日常生活中不可或缺的一部分。Tango通过使用三种核心技术为移动设备提供这种理解：运动跟踪，区域学习和深度感知。

Motion Tracking overview 运动跟踪概述

Motion Tracking means that a Tango device can track its own movementand orientation through 3D space. Walk around with a device and move itforward, backward, up, or down, or tilt it in any direction, and it can tell youwhere it is and which way it’s facing. It’s similar to how a mouse works, butinstead of moving around on a flat surface, the world is your mousepad.

运动跟踪意味着Tango设备可以通过3D空间跟踪其自身的运动和方向。用设备走动，向前，向后，向上或向下移动，或向任何方向倾斜，它可以告诉你它在哪里，它面对的方式。它类似于鼠标的工作原理，但不是在平坦的表面上移动，世界是你的鼠标垫。

Area Learning overview 区域学习概述

Human beings learn to recognize where they are in an environment by noticingthe features around them: a doorway, a staircase, the way to the nearestrestroom. Tango gives your mobile device the same ability. With MotionTracking alone, the device “sees” the visual features of the area it is movingthrough but doesn’t “remember” them.

人类通过注意它们周围的特征来学习识别他们在环境中的位置：门口，楼梯，通往最近的洗手间的方式。探戈给您的移动设备相同的能力。仅使用运动跟踪，设备“看到”它正在移动通过的区域的视觉特征，但不“记住”它们。

With Area Learning turned on, the device not only remembers what it sees, itcan also save and recall that information. When you enter a PReviously savedarea, the device uses a process called localization to recognize where you arein the area. This feature opens up a wide range of creative applications. Thedevice also uses Area Learning to improve the accuracy of Motion Tracking.

启用区域学习后，设备不仅会记住它看到的内容，还可以保存和调用该信息。当您输入先前保存的区域时，设备使用称为本地化的过程来识别您在该区域中的位置。此功能打开了广泛的创意应用程序。该设备还使用区域学习来提高运动跟踪的准确性。

Depth Perception overview 深度感知概述

With depth perception, your device can understand the shape of yoursurroundings. This lets you create “augmented reality,” where virtual objectsnot only appear to be a part of your actual environment, they can also interactwith that environment. One example: you create a virtual character who jumpsonto and then skitters across a real-world table top.

使用深度感知，您的设备可以了解您的周围环境的形状。这允许您创建“增强现实”，其中虚拟对象不仅看起来像是您的实际环境的一部分，他们也可以与该环境交互。一个例子：你创建一个虚拟角色，跳到现实世界的桌面上然后跳过。
