I am looking for good tutorials that go through every step of creating an AR application. It would be beneficial if it also covers some of the theory behind optics and such. ...
I have an application that defines a real world rectangle on top of an image/photograph, of course in 2D it may not be a rectangle because you are looking at it from an angle. The problem is, say that the rectangle needs to have grid lines drawn on it, for example if it is 3x5 so I need to draw 2 lines from side 1 to side 3, and 4 lines...
Hi everyone, I tried everything but no success.I am having big problems in importing files.So many error.... spent 5 hours but nothing. I successfully able to create project using collada parser but all the problems are coming when i am using import org.papervision3d.objects.parsers.DAE; There were some files missing and when i tried to ...
Hi, whenever i am trying to use an animate.dae file(i am creating small project using flartoolkit+papervision3d+ascollada) .The flash player is reporting me the errors pasted below.If i am pressing continue then i can see my .dae file but without animation :( And Please note that i am not using any heavy animation. ERROR TypeError: Err...
Hey Could anyone advise on whether the iPhone SDK 3.0 still does not allow access to the raw camera pixel data This is how it was with all the previous SDKs and I thought it must have been a move by Apple to ensure they were the first ones to implement the video recording. Since 3.0 now has video recording, and as far as im aware the ...
Hi there, I can display images on marker using flarToolkit in flash as3 but can anyone suggest a good link/tutorial which explains how to use animation with augmented reality in flash? ...
Hi, Does anyone know any good book or web resource for geometric and mathematical fundamentals of augmented reality? Thanks! ...
Does anyone know a way to take an image captured on the iphone's camera, and do some image processing (e.g. edge detection, skeletization), and then overlay parts of the processed image on the original image (e.g. only the highlighted edges). More generically how do I create a UImage with transparency (do I just scale the image and ove...
Is it possible to use java to write into a webcam stream? I've tried JMF and got it to capture the image but couldn't find a possibility to write into the stream. ...
I'm capturing the Stream from a webcam and would like to draw something on top of the video image. I try that in the example below, the problem is that the other component is always in the background no matter how I arrange the components. Is there a way do solve this? public class SwingCapture extends JPanel { private static final...
I've come across MANY AR libraries/SDKs/APIs, all of them are marker-based, until I found this video, from the description and the comments, it looks like he's using SIFT to detect the object and follow it around. I need to do that for Android, so I'm gonna need a full implementation of SIFT in pure Java. I'm willing to do that but I n...
I'm trying to more or less recreate Johnny Lee's Wii head tracking app, but using an augmented reality toolkit for the tracking, and WPF for graphics. To do this, I need to create a perspective camera using the top, bottom, right, and left parameters to create my viewing frustum, instead of field of view and aspect ratio (to those famili...
After asking here and trying both SURF and SIFT, none of them seams to be efficient enough to generate interest points fast enough to track a stream from the camera. SURF, for example, takes around 3 seconds to generate interest points for an image, that's way too slow to track a video coming from a web cam, and it'll be even worse when...
Hi, I recently bought the book: Augmented Reality: A Practical Guide (http://pragprog.com/titles/cfar/augmented-reality). It has example code that it says runs on Windows, MacOS and Linux. But I can't get the binaries to run. Has anyone got this book and got the binaries to run on ubuntu? I also can't figure out how to compile the exa...
I'm working on locating an iPhone device in 3D space. I can use lat/long to detect physical location, I can use the magnetometer to figure out the direction they're facing, and I might be able to use the accelerometer to figure out how their device is oriented, but I can't figure out a way to get height of the device off the floor. Spe...
In an AR app whereby you annotate objects or buildings in a camera view, I want to understand the role, that different hardware bits - on the phone (iPhone/Android) - play to achieve the AR effect. Please elaborate more on the following: Camera: provides the 2D view of reality. GPS: provides the longitude,latitude of the device. Compas...
Hi, I am experimenting a bit with the iPhone 3GS and its magnetic sensors. It is quite simple to get the heading and the angle of the north pole seen from the top of the device. Also getting the position of the device itself via accelerometer is quite easy. But getting it all together deserves some math knowledge regarding vector calcula...
Hi there, For an augmented reality project I want to display a high resolution live camera feed. Then in front of this I want to display a model than can be manipulated (translate, stretch, etc) in real time. I was going to use OpenSceneGraph but realized it will be a lot of work to get the manipulations working. So I would prefer a mo...
I need to change (lower) the camera exposure from inside a program. The documented API I found (DirectShow) don't seem to work. Any help is appreciated. ...
I am using artoolkit to create an augmented reality based project.I can load vrml 3d objects in the video feed using openvrml. Now I wanted to load a bitmap or any other image file like jpg,png etc file on the marker in the video feed.How do I go about achieving this? ...
