ARToolKit uses computer vision techniques to calculate the real camera viewpoint relative to a real world marker. There are several steps as shown in figures 3-5.

ARToolKit is an open-source computer tracking library for creation of strong augmented reality applications that overlay virtual imagery on the real world. Currently, it is maintained as an open-source project hosted on GitHub.^[2] ARToolKit is a very widely used AR tracking library with over 160,000 downloads on its last public release in 2004.^{[3][obsolete source]}

In order to create strong augmented reality, it uses video tracking capabilities that calculate the real camera position and orientation relative to square physical markers or natural feature markers in real time. Once the real camera position is known a virtual camera can be positioned at the same point and 3D computer graphics models drawn exactly overlaid on the real marker. So ARToolKit solves two of the key problems in Augmented Reality; viewpoint tracking and virtual object interaction.

ARToolKit was originally developed by Hirokazu Kato of Nara Institute of Science and Technology in 1999^[4] and was released by the University of Washington HIT Lab. In 2001 ARToolWorks was incorporated, and v1.0 of the open-source version of ARToolKit was released through the HIT Lab. ARToolKit was one of the first AR SDKs for mobile, seen running first on Symbian in 2005,^[5] then iOS with the iPhone 3G in 2008,^[6] and finally Android as early as 2010^[7] with a professional version by ARToolWorks later in 2011.

ARToolKit was acquired by DAQRI and re-released open-source starting at version 5.2 on May 13, 2015,^[8] including all of the features that were previously only available in the professional licensed version. Among these features are mobile support and natural feature tracking.

Ben Vaughan and Phil Lamb, the former CEO and CTO of ARToolworks, created artoolkitX to ensure that the software is developed and maintained and the ARToolKit community continues to be supported. artoolkitX is supported by Realmax Inc, a Chinese AR company that develops AR hardware and software.

Features[edit]

• Single-camera or stereo-camera (camera position/orientation tracking).
• Tracking of simple black squares (any square marker patterns).
• Tracking of planar images (natural feature markers).
• Camera calibration, optical stereo calibration, square marker generation, and natural feature marker generation utilities.
• Plugins for Unity and OpenSceneGraph.
• Optical head-mounted display support.
• Free and open source software.
• Fast enough for real time AR applications.

Operating systems[edit]

The current version of ARToolKit supports Microsoft Windows, Mac OS X, Linux, iOS, and Android platforms. Other versions of ARToolKit have also been ported to Symbian, and Windows Phone to support mobile AR applications.

ARToolKit is also available as a plugin for the Unitygame engine for example to align a virtual camera within Unity with a real-world camera relative to a tracked marker target and taking care of communicating with the camera. The plugin supports Unity on OS X, Unity on Windows, Unity on Android, and Unity on iOS.^[9]

Hey everybody,

during this rainy summer I figured, there could be the perfect moment for you to get started with augmented reality, too! You have seen the demos on youtube? You were intrigued by movie effects? But how could you try it out easily and – for now – without any skills in augmented reality or programming? Here is the answer below! Try it out! All you need is a neat webcam or even a crappy one and then try one or all of the following demos to get a first impression yourself! No movie, but all real-time in your hands!

1. Transform yourself!

Go to www.weareautobots.com and install the plug-in, when asked. After some loading you will see your webcam image as a live feed in your browser and when you keep your face inside the camera, you’ll be automatically transformed into an Autobot from Transformers!

(This demos uses face recognition and tracking. Nothing else is needed besides your human looks. But that one you’ll need, since the face recognition will look for two eyeballs, one nose, etc…)

2. Fight the dragon on your desktop!

Go to www.metaio.com/design/demo and download the Unifeye Design Demo Installer (Windows only). After installing, go to the subfolder (probably:) C:Program FilesmetaioUnifeye Design DemoexamplesscenesKnights&Dragons and print the file Drache_Marker_1.jpg.

Now start the Unifeye Design Demo link on your desktop. At the bottom of the screen you will see video play controls (rwd, play, stop, fwd), right next to those you’ll have three vertically aligned buttons: click the lower one and then select your webcam on the right. You’ll see your video feed. Go to File > Open and select examples > scenes > knights&dragons > DemoScene_Knights&Dragons.scef. Now hold the printed paper into the view!

(This demo uses feature based tracking, i.e. you have to use an image as a reference. In this case this is the castle image you printed. The whole tool can do much more and you can even import your own VRML files. If you have no clue, what that means, don’t worry. Try one of the other demos, that are shipped along.)

3. Go to where it all started!

Artoolkit Tutorial

Download the ARToolkit package from www.hitl.washington.edu/artoolkit/download and unpack it. If you run Windows, copy this file into the unpacked folder ARToolKitbin or download the OpenGL GLUT files from the web and copy them to your folder. Now print the file ARToolKitpatternspattHiro.pdf and start the program simpleVRML. You will see a bee buzzing above a flower – on your hand!

(This demo uses marker based tracking, i.e. you have to hold a black/white pattern into the camera’s view. This printed square will be recognised as the anchor, where the program will put the graphics. As you move around the pattern, the 3D objects will move along. This last demo ships with all the C source code. So if you are interested in learning more about augmented reality and starting to program your own application, continue reading on the ARToolkit website for tutorials or go to the Studierstube to get the ARToolkit Plus, that might be more comfortable or convenient for you. Both are free of charge.)

Of course, there are dozens of different free and more commercial systems, but for now, I only wanted to give you a brief and free impression, of what’s easily possible. Fascinated? Would you love further getting-started’s? Need help with my micro tutorial? Let me know! :-)
