Unity+高通Vuforia SDK——AR

一、AR概念： 增强现实（Augmented Reality，简称AR），是在虚拟现实的基础上发展起来的新技术，也被称之为混合现实。是通过计算机系统提供的信息增加用户对现实世界感知的技术，将虚拟的信息应用到真实世界，并将计算机生成的虚拟物体、场景或系统提示信息叠加到真实场景中，从而实现对现实的增强。 二、工具： 在这里我们主要是用高通的Vuforia SDK来演示如何在Unity下制作一个简单的AR的demo，Vuforia SDK是一套很完整的可以直接调用的AR API，而假如想深入了解SDK内部的关于AR中图片识别以及跟踪的算法，我们需要从Open CV入手。 1.Unity——我使用的是Unity5.3.1f版本 2.Vuforia SDK插件——从官网（https://developer.vuforia.com/downloads/sdk）下载最新的5.5的Unity专用版本 三、实战： 1.在Unity中新建一个3D项目，取名为TestAR 2.导入下载好的Vuforia SDK插件包：vuforia-unity-5-5-9.unitypackage 3.导入成功后，再Assets目录下回多出一个Vuforia文件目录和一些其他的辅助文件 4.将默认场景中的Main Camera删掉，并将Vuforia/Prefabs目录下的ARCamera相机拖至场景中 5

Vuforia AR SDK入门

Vuforia是一个能让应用拥有视觉的软件平台。开发者借助它可以很轻松地为任何应用添加先进计算机视觉功能，允许你识别图片和物体，或者在真实世界中重建环境内容。 如果你现在正在制作一些可交互的市场活动项目或者一款游戏、或者一款用于提升购物体验的产品可视化应用，Vuforia SDK都能满足你的需求。 Vuforia的关键特性包括对图片、物体、文本和标记的识别和追踪，以及重建环境。 Vuforia 5.5版本引入了对头部转动和手势追踪的支持，同时还具备带失真校正的立体渲染能力，使得它可以在数字眼睛上的AR/VR应用中正常运行。它同时还引入了Mixed Reality Controller API来开发具有AR和VR互补模式的混合现实应用。这些混合现实应用可以在真实产品上显示AR虚拟内容，也可以让用户沉浸在全虚拟的VR内容中。Vuforia允许你通过扫描目标来解锁额外的VR内容。 特性 Features Vuforia的识别和追踪能力即使是在大量的图片和物体情况下都可以正常使用。 Image Targets 是指平面图像，例如打印出的媒体内容，或者商品包装 Multi-Targets 是指多个Image Target创建的图片集合，能被分配到不同几何形状（比如盒子，我觉得这里是指类似于Unity天空盒子一样的东西），或者可以任意排列在平坦表面上。 Cylinder Targets

问题 I am using Vuforia SDK to build my AR app. By using trackableResult->getPose(), I can get a model view matrix of the target frame marker. But I also need pure view matrix to do some calculations. Is there any way to get it? 回答1: To follow on from peedee's comment above, here is a picture I found extremely helpful, linked to from this web page.
