augmented-reality

问题 I'd like to create an app (on iPhone) which does this: I have a template image (a logo or any object) and I'd like to find that in camera view and put a layer on the place of where it is found and tracking it! It is a markless AR with OpenCV! I read some docs and books and Q&A-s here, but sadly actually i'd like to create something like this or something like this. If anyone can send to me some source code or a really useful tutorial (step by step) i'd really be happy!!! Thank you! 回答1:

问题 I'm am working on a basic augmented reality application on Android. What I did so far is detect a square with opencv and then using cvFindExtrinsicCameraParams2() I calculated a rotation and translation vector. For this I used 4 object points, which are just the corners of a square around (0,0,0) and the 4 corners of the square in the image. This yields me a pretty good rotation and translation matrix. I also calculated the rotation matrix with cvRodrigues2() since using this is easier than

问题 I saw that someone has made an app that tracks your feet using the camera, so that you can kick a virtual football on your iPhone screen. How could you do something like this? Does anyone know of any code examples or other information about using the iPhone camera for detecting objects and tracking them? 回答1: I just gave a talk at SecondConf where I demonstrated the use of the iPhone's camera to track a colored object using OpenGL ES 2.0 shaders. The post accompanying that talk, including my

问题 Currently I'm writing an augmented reality app and I have some problems to get the objects on my screen. It's very frustrating for me that I'm not able to transform gps-points to the correspending screen-points on my android device. I've read many articles and many other posts on stackoverflow (I've already asked similar questions) but I still need your help. I did the perspective projection which is explained in wikipedia. What do I have to do with the result of the perspective projection to

问题 I'm in the process of learning both ARKit and Scenekit concurrently, and it's been a bit of a challenge. With a ARWorldTrackingSessionConfiguration session created, I was wondering if anyone knew of a way to get the position of the user's 'camera' in the scene session. The idea is I want to animate an object towards the user's current position. let reaperScene = SCNScene(named: "reaper.dae")! let reaperNode = reaperScene.rootNode.childNode(withName: "reaper", recursively: true)! reaperNode

问题 Is there any Augmented Reality Framework which support marketless tracking on android phone ? i have searched a lot but mostly are marker based framework Framework that does not support Marker less Detection Qualcomm ( QCAR ) ARToolkit NyARToolKit someone has suggested Ferns but no idea how well that product is for android phones 回答1: There aren't any to my knowledge. There are some videos floating around that demonstrate a PTAM implementation on Android phones from a korean university, but
