Augmented reality (AR) is an enhanced version of the real physical world that is achieved through the use of digital visual elements delivered via technology (webcam, camera). Multi Media Net developed, both for its virtual studio and mobile devices, applications of augmented realty.
The camera tracking systems used by Multi Media Net for its augmented reality services are two:
- Mechanical tracking
- Tag tracking
Mechanical tracking: This technology requires the installation of a camera on a mechanical structure (tripod, arm…) that has electronic components that detect all the system movements. It is used mainly for conventional TV studios. All the data detected by the mechanical encoders are “packaged” and sent to the graphics engine through a serial port by an electronic control unit.
Optical tracking system (Tag): With this technology you do not need any electromechanical devices (the camera can be handheld on the shoulder). The process of camera tracking, in this case, occurs through the camera angle observation of a real object called TAG (a white tile with a black frame in our case, which can also be branded) that embraces at least 1/10 of the entire shot. The Tag can be also “handled” in movement…for example, holding it by hand and telling the specs of the 3D model used in that moment. Both systems are developed exclusively by Multi Media Net.
