Augmented Reality Video Overlay
In the future, augmented reality video overlays will be much more common. This technology will allow for augmented reality gaming and interaction. We are already seeing this with Project Natal, where augmented reality programs and phones are used in the process of creating an artificial womb. However, this was just a laboratory application. We won’t know the full potential of this technology for another decade. One thing is for sure though, this technology has come a long way since its humble beginning.
Augmented reality refers to using computer generated images or videos to interact with real-world situations. Video overlays work in two different ways. One works by using light fields to represent objects. The light coming from these cameras and from other sources (such as streetlights, backdrops, etc.) are combined with video data from the real world to create the optical illusions we see.
The second type of augmented reality uses what’s called an image tracking camera. A computer vision system that tracks the position and movement of an object with the use of infrared lasers. In the case of augmented reality, this camera can also detect a particular person and then determine where that person is within the scene. Once that information is stored, the system can use it to create a virtual representation of that person in the environment of the user. For example, if a user is walking through a grocery store, an image of that person can be projected onto the screen, so that he or she can move around easily and shoplift without running into trouble.
The next step up in this technology is the digital light processing camera. These processing cameras take a digital still photograph and then process it into a digital three-dimensional image. This digital image can then be superimposed over a series of live images taken from real-world locations. Digital light processing cameras are often used with augmented reality video overlay systems to create a moving video overlay over the real-world images.
For something completely different, you might want to use a scene capture camera to create augmented reality. Scene capture allows a user’s camera to film their environment in whatever way they desire. This could include the use of augmented reality filters, such as dark under eye shades to brighten up a scene, or reflections from small lights on nearby walls. The recorded scene could be shown on a TV screen, or the user could use that same scene as a video overlay in their cell phone.
Of course, not everything captured with a video camera will make it into the real world. Sometimes, users capture images with a digital camera but do not want those images included in the live presentation. They may have their own video camera, or they may be using something like an Apple iPhone, and in that case, all they need is a good computer program. Augmented reality video overlays can be made to work with any video camera.
Of course, there’s no limit to what can be used with an augmented reality video overlay. Many different types of digital imaging work can be overlaid on a live video feed, to create the effect of a camera panning across the room as the user walks through. This technique is often used by architects when preparing plans for a home. It makes the plans more realistic and less expensive to build. And the same thing can be applied to movies: when someone walks into a movie theater, their eye will be drawn from the screen to the avatars (aliens) that are placed in the front of the screen, which can include the likes of birds, cars and other scenery.
In this day and age, every image captured with a digital camera can be stored digitally and used in augmented reality video overlays. Users simply have to point their camera at the desired location on the screen, which will then become the scene in the video. Digital images can then be blended with real world data to give the exact effect. This makes augmented reality video overlays an incredibly versatile tool, which can be used to enhance just about any digital image.
