Elements AR System 3 D

The RemoteARSystem is an implementation of an Augmented Reality (AR) system that uses the images from a remote webcam.
Here you can see the available methods.

 

The AR system of EJS is based on ARToolkit, and requires markers that the system can recognize and (optionally) a calibration file for your particular camera.

 

Here is a collection of over a hundred markers in PDF format, and in GIF format.

 

Here are some calibration files for particular cameras. Though these files are not absolutely necessary if you don’t need much accuracy.
