问题 I am a beginner in the field of augmented reality, working on applications that create plans of buildings (floor plan, room plan, etc with accurate measurements ) using a smartphone. So I am researching about the best AR SDK which can be used for this. There are not many articles pitting Vuforia against ARCore and ARKit. Please suggest the best SDK to use, pros and cons of each. 回答1: Updated: October 30, 2019 . TL;DR Google ARCore allows you build apps for Android and iOS, with Apple ARKit

Load AR-model through button tap in Android

问题 I have made a basic AR-app using Unity & Vuforia and exported it to Android, so I can add some activities there. When I scan the image with the AR-camera in the app, a model pops up. Nothing new there. What I want to achieve, is that when a user taps a button in some activity, lets say the text on the button is "Elephant", the AR-camera in the app opens, scans the image and loads a model of an Elephant. My question is: is this possible? Is it possible to load a model depending on the user

作业内容 1、 图片识别与建模 2、 虚拟按键小游戏 图像识别与建模 采用的系统 macos, unity3d v2018.4.13f1 环境的配置 与windows上的配置不同,在Vuforia官网上没有安装到macos的unity上面的安装包。(windows系统的话直接下载第二个文件,解压后会有一个exe文件,在unity的项目目录下安装即可) 经过查找找到了安装Vuforia的方法,就是在安装unity的时候会提示是否安装Vuforia,如果之前安装的时候勾选了,就可以直接用了,如果没有安装,就需要重新安装一次,在安装的时候勾选它即可(由于安装时没有截图,所以这里就不发那个过程了) 安装成功后在asset点击右键可以看到Vuforia的相关信息 然后就可以按照老师课件给出的步骤一步步实现。这里给出大概的步骤。 将项目中的摄像头全部删除 添加AR Camera 在AR camera中点击open vuforia engine configuration 在global中输入在Vuforia网站上之前创建的key 导入database,与课件中的方法一样,先从网站中把自己创建的数据库下载下来,再import进项目即可。这里导入数据库之后同步即可,不需要再进行其他的设置。(其已经自动添加进去了) 点击file->build setting(这一步可省略) 下载android

问题 I am working on a project using Unity/Vuforia to build an Augmented Reality app for Android and need some help. I have a ball appear on screen when the imagetarget is found. I cannot figure out how to get the ball to move around. I can use virtual buttons, but am looking to find a way of having the forward/back/left/right buttons (or a joystick) on the android screen which will control the ball. Can anyone offer any advice or point me in the right direction? I've been searching for hours and

Vuforia AR 脱卡功能的实现

瘦欲@ 提交于 2019-12-14 05:45:23
在AR的开发过程中有时候会需要用到脱卡功能,脱卡功能是指即使识别图丢失的情况下被识别出来的模型也不会消失; 实现脱卡功能有以下几种解决思路: 在Vuforia插件的默认条件下,当识别图离开摄像头时间,ImageTarget 的SetActive (false),所以其子物体(model)也就不显示了,因此解决的办法就是在Target (false)时间将模型放到一个合适的位置,这样就能实现脱卡,当Target (true)时,再回到原来位置; 将Vuforia 中默认的设定修改下,当识别图离开时不做模型的隐藏即可, 当然这两种方法根源就是当识别图在摄像画面中消失后不隐藏模型; 首先来看下识别图消失,模型跟着隐藏也就是不脱卡的根源是哪里: 经过查找不难发现在ImageTarget 物体上有一个脚本组件名为“DefaultTrackableEventHandler” ,在这个脚本里面主要控制识别图显示和丢失时的两种操作: 在OnTrackingFound和OnTrakingLost两个方法中分别控制了ImageTarget的子物体的渲染组件及碰撞体组件的显示与隐藏; 既然问题的根源已经找到了,那么我们只需要让模型在显示之后不隐藏,就可以实现脱卡功能; 接下来进入到脱卡功能制作过程: 重新写识别图时显示与隐藏被识别出的物体的方法: 这里直接上代码: using System .

Using MRTK and Vuforia in Unity - What Camera to choose?

跟風遠走 提交于 2019-12-14 02:05:02
问题 Im new to AR and set up the last days MRTK and Vuforia on Unity. Both operated fine independently and now I want to use both in one project. But the problem is that both have a camera. MRTK has its own MixedRealityCamera and Vuforia the ARCamera. How to use one camera, using MRTK and Vuforia? I guess using two cameras in one scene is not good. I found this post: https://github.com/Microsoft/MixedRealityToolkit-Unity/issues/1461#issuecomment-373714387 So I tried to transfer the components from

How to properly integrate Unity + Vuforia into an existing native iOS Project?

问题 We have created a project with Unity 2017.3 and Vuforia 6.0.114 and need to integrate it into a native iOS App with already existing AppDelegate and existing ViewContollers. We still want to launch our own AppDelegate and starting ViewController but on some point later the Unity+Vuforia-Controller shall be entered. We are familiar with the process of integrating a Unity App into a native iOS App itself and we made everything work fine as long as there is no Vuforia involved. The problem is

How to calculate the camera position from Vuforia GL matrix?

醉酒当歌 提交于 2019-12-13 15:25:32
问题 I calculate the camera position of a SCNScene that is rendered in Vuforia. However the object is not staying fixed on the marker but jumping around when moving. The cube in the scene appears only orthographically, no matter how the device is moved around the sides cannot be seen. The camera position is calculated with every frame: // Get model view matrix Vuforia::Matrix44F modelViewMatrix = Vuforia::Tool::convertPose2GLMatrix(result->getPose()); // Convert to extrinsic matrix SCNMatrix4
