augmented-reality

问题 I am interested in implementing an Augmented Reality application for mobile phones using Adobe Flash Platform. Can you please let me know if any sources is available for me to find out how to start? I'm not sure what software I need to use to implement AR but as I can understand I need: ARToolKit Marker Generator to create the marker matching with the 3D image, then FLARToolKit to analyze the image from the marker and Papervision3D to create an object that shares that same space with the

问题 How can I make sure my app on iOS AppStore only show compatibility for ARKit enabled devices only? 回答1: The key is arkit for your info.plist file under Required device capabilities. Apple documentation on plist keys (UIRequiredDeviceCapabilities). Key : arkit Description : Include this key if your app requires support for ARKit on the device (that is, an iOS device with an A9 or later processor). Minimum version : iOS 11.0 One important caveat for existing apps is that Apple does not allow

问题 Hey guys i am in a problem related to augmented reality please help PROBLEM I need to show the label on camera overlay for any object with movement for example i have 4 object say four house in four direction i.e. south north east west and when i see to north i should be able to see the only single label for that house on that label there will be some information say house name so how to do it when i move to south direction north label should start move aside and south label should start to

问题 I am following the ARCore sample (https://github.com/google-ar/arcore-android-sdk) and I am trying to remove object 3d (andy) already added. How can I detect if an tap event with ARCore hits an already added 3d object? 回答1: Using a listener is quite common approach in such situation: private Node getModel() { Node node = new Node(); node.setRenderable(modelRenderable); Context cont = this; node.setOnTapListener((v, event) -> { Toast.makeText( cont, "Model was touched", Toast.LENGTH_LONG) //

问题 Im developing an iOS Augmented Reality application using OpenCV. I'm having issues creating the camera projection matrix to allow the OpenGL overlay to map directly on top of the marker. I feel this is due to my iPhone 6 camera not being correctly calibrated to the application. I know there is OpenCV code to calibrate webcams etc using the chess board, but I can't find a way to calibrate my embedded iPhone camera. Is there a way? Or are there known estimate values for iPhone 6? Which include:

问题 I'm currently trying to implement an alternate method to webcam-based AR using an external tracking system. I have everything in my environment configured save for the extrinsic calibration. I decided to use cv::solvePnP() as it supposedly does pretty much exactly I want, but after two weeks I am pulling my hair out trying to get it to work. A diagram below shows my configuration. c1 is my camera, c2 is the optical tracker I'm using, M is the tracked marker attached to the camera, and ch is

问题 What sensors does ARCore use: single camera, dual-camera, IMU, etc. in a compatible phone? Also, is ARCore dynamic enough to still work if a sensor is not available by switching to a less accurate version of itself? 回答1: UPDATED November 24, 2019 . Google's ARCore , as well as Apple's ARKit , use the same types of sensors to track a real-world scene. ARCore uses a single RGB camera along with IMU device, what is a combination of an accelerometer , magnetometer and a gyroscope . Your phone can

问题 I want to develop an application which runs on iPhone / Android / Windows Phone 7 smartphones and is able to recognize a marker and place augmented reality content on it. Is there any common framework which I could use for that task? 回答1: This is probably the closest you'll get: http://nyatla.jp/nyartoolkit/wiki/index.php?FrontPage.en 回答2: Not sure about Android or iPhone, but Kevin Marshall has done some proof-of-concept work on Windows Phone 7. You should keep in mind though, that augmented
