Hi, I'm trying to use NyARToolkit for android to get the rotation of a marker. I am trying to automatically straighten a document that has been photographed using the camera. Does anyone know how I would go about this, using NyARtoolkit or another if necessary? ...
Hi With the new additions to the OS and the hardware, iPhone apps can now do some serious augmented reality coolness. What are the instant benefots to the obj c crowd? Are there any frameworks to aid in the creation of AR apps for Obj C devs and if so, can they be easily ported to MT with the btouch project? w:// ...
Prior to the release of the new SDK there has been some buzz about Apple finally providing access to live camera data: I've been reading through Apple's documentation but have not found any reference to this. Now that the NDA has been lifted, does anyone know where this new functionality is documented? ...
Just starting to play with Augmented Reality on the iPhone ... and I have some questions: How do you position elements on the screen? I assume that it is based on a given longitude, latitude and altitude (but I could be wrong)??? Any solid resources, tutorials, etc... dedicated to building AR type apps for iOS? Thanks much ...
Hi, I'm searching for a library similar to ARToolKit. It needs to support processing a single image and search that image for a marker. If it finds one I want it to return the camera angle / viewpoint based of the marker. I couldn't find anything via Google, does something like this exist? ...
Hi, Im trying to do the following and I would like if its possible before losing too much time on it. I want to use something like FLARToolKit to do the following: Upon detecting a marker the object to be shown is a video on 2d plane. Anyone has done it or has some examples/tutorials? How hard will it be to implement? Thank you ...
I have a camera mounted on a tripod its motion is restricted to pan and tilt rotation. It is looking at dot that is at a known location directly in front of the camera. If the camera looks at the dot and gets the 2d coordinate of it, is it possible to deduce the camera's rotation so that I can overlay some 3d models properly aligned to...
Does anyone know how I can add web-cam into my website so all my users can print the AR code and view it on my website? Thanks. ...
Hi Im working on and Augmented reality app for android 2.2 but i want in integrate a face recognition module... i try to use the findFaces method from FaceDetector class but it recive a bitmap... and i want to send a camera preview any idea? thnks ...
I have a windows mobile 6.1 prof application. I want to make a fake augmented reality application. So while in the capture camera mode. I want to also be able to paint something over the camera view. is that possible? Also if you know some dll's or API's about augmented reality (free or not) please welcome. ...
Hello everyone, I'm going to try to explain my situation as clearly as possible. I'm not looking for solutions, but for ideas that can give me some direction as what to do. What I have seen on the web is that AR is usually done with a webcam feed on a screen or with a head mounted display. In this case, we want to overlay simple object...
Hi, I uploaded an example image for better understanding: http://www.imagebanana.com/view/kaja46ko/test.jpg In the image you can see some scanlines and a marker (the white retangle with the circle in it). I want opencv to go along a specified area (in the example outlined trough the scanlines) that should be around 5x5. If that area co...
I'm trying to figure out how to implement a basic augmented reality application that uses a piece of (real) paper to navigate (simple rotate, zoom) a virtual 3d or pseudo-3d space. The example implementation that comes to mind is the Harry Potter 3D Augmented Reality ad, where you can take a piece of paper, point it at your webcam (at ...
I'm starting a new project that'd involve using several SDK's including: Intel Atom Developer SDK text to speech SDK (Suggestions?) webcam and augmented reality support of some sort (Suggestions?) I currently have 2008, but I can also install 2010. Is there any reason to use 2010 for this project? ...
Need some pointers to resources for learning about Image processing used in Augmented Reality. I'm doing a project/paper on image processing. I found Augmented Reality personally to be the coolest thing. I'd be very happy and grateful if someone could explain or point to books or web sites which explain all about the concepts behind the ...
Anybody know how to determine whether two sectors of the same circle intersect? Let's say I have a sector A, expressed by starting and ending angles A1 and A2, and a sector B, expressed by starting angle B1 and ending angle B2. All angles ranges from 0..2*PI radians (or 0..360 degrees). How to determine whether angle A intersects wit...
Hi to all, Does someone know the field of view values for the new iPhone4 camera? I'm doing some AR app's, and I want to know the horizontal and vertical angle of the rear camera. Thanks! ...
I'd like to add an OpenGL ES view as an overlay to my camera view. From this question and its anser I came to know the two field angles of the iPhone 4 rear camera. How can I properly set the volume view and its perspective in the OpenGL ES view? Shall I use glFrustum or glOrthof? (I've seen that gluPerspective takes just one angle as...
Is there a way to find out or calculate the field of view (FOV) an iPhone camera has through calls to the APIs? Or is it something you have to physically and manually find out for yourself? If it cannot be fetched or calculated with the APIs, but instead has to be hard-coded into an app, then what's the best way to find out what kind of...
Hey Guys I have the following simple Code : WhereAmIViewController.h #import <UIKit/UIKit.h> #import <CoreLocation/CoreLocation.h> @interface WhereAmIViewController : UIViewController <CLLocationManagerDelegate> { CLLocationManager *locationManager; CLLocation *startingPoint; IBOutlet UILabel *lati...
