问题 Is it possible to use Vuforia without a camera for image tracking? Basically I would like a function I could call with an image as a indata parameter and coordinates of a image target as a result. Does that exist? 回答1: It is unfortunately not possible. I've been looking for such an option myself several times while working on a Moodstocks (image recognition SDK) / Vuforia mashup (see these 2 blog posts if you are interested in it), but the Vuforia SDK prevents the use of any other source than

问题 The company I work is building an android application with vuforia(version 5.x) and Unity3D(version 5.3.5f1 Personal) integration. In newest android devices the camera is opening ok but We're facing problem in older devices like Samsung Galaxy S2(4.1.2). When the device open the camera via vuforia the screen is black and if we try to take a picture the image is obviously black as well. My activity is only instantiating the unity player and it is like code below: public class MainActivity

问题 I want to bypass Vuforia's display handling of the camera image and pose of framemarkers on iOS, is this possible? 回答1: In - (void)QCAR_onUpdate:(QCAR::State *)state you can grab the camera data and the marker poses. Camera image data QCAR::Frame frame = state->getFrame(); for (int i = 0; i < frame.getNumImages(); i++) { const QCAR::Image *image = frame.getImage(i); if (image->getFormat() == kQCARFrameFormat) { const void *pixelData = image->getPixels(); int width = image->getWidth(); int

Is it possible to track objects in ARKit like in Vuforia?

问题 I couldn't find any information if Apple's ARKit supports 3D object tracking (or even image tracking) like Vuforia does. I don't want to place a 3D model just anywhere in the world. Instead I want to detect a specific 3D object and place AR objects in front and on top of that object. Simple example: I want to track a specific toy car in the real world and add a spoiler on top of it in the AR scene. Can someone provide me information wether that is possible or not? 回答1: Update for iOS 12: In

AR小游戏 牧师与恶魔 前言 这是中山大学数据科学与计算机学院2019年3D游戏编程与设计的第十一次作业 所有项目与代码已上传至github当中，欢迎大家访问。 github个人主页: https://starashzero.github.io 3D游戏编程与设计主页: https://starashzero.github.io/3DGameDesign 本次作业项目地址: https://github.com/StarashZero/3DGameDesign/tree/master/hw11 项目要求 图片识别与建模 虚拟按键小游戏 项目简介 我将之前做过的牧师与恶魔实现为AR小游戏，设置两个虚拟按键对应提示、重开两个功能 项目改动不大，但是碰到的坑比写的代码还多，接下来我会对一些坑和解决办法进行总结 排雷 无法开启Vuforia Augmented Reality Supported 提示某文件not registered Vuforia无法成功导入，或每次导入需重启 解决办法: 应该是版本兼容问题，下载安装Unity 2018.4.14f1版本可解决 无法将动态生成的对象的parent设置为ImageTarget，通过代码设置后仍为null 解决办法: 未彻底解决，目前是将动态生成的对象改为直接挂载再ImageTarget下 运行后ImageTarget下的对象错位

Vuforia: How to change teapot with a text in the image targets example?

问题 How do I change the teapot with a text content in Vuforia's Image Target example? The example is available at : https://developer.vuforia.com/resources/sample-apps/image-targets-sample-app 回答1: I tried to access the links mbrenon gave. Unfortunately they didn't load. My solution: The reason why you have a Teapot is because Vuforia is using that class as the image to be shown. In order to have a plane text, I created my own PlaneTextClass.
