Augmented Reality Mobile App Development
Implementation of new technologies is a necessary step for every kind of business. Especially when it comes to mobile app development, the most important is to keep up to date by creating new types of the content as well as utilizing new tools.
That is why nowadays many companies provide their customers with immersive virtual reality experience using VR headsets or interactive mobile applications that augment the real environment with digital data.
As the result, virtual reality and augmented reality technologies have become a real breakthrough that turned upside down various industries, including real estate, game development, healthcare, education and many others.
Speaking about augmented reality app development, there are two major approach, marker-based and markerless. Each type is widely used for different purposes and this article is to discuss marker-based AR type in details.
Marker-based Tracking Process for AR Mobile App Development
The main task of AR mobile app developers is to align digital data with the real environment by means of appropriate SDK (software development kit) and computer graphics techniques.
The marker-based tracking uses visual markers that can be detected with a camera of any device. These markers, usually QR codes, provide the information on the correct scale and the pose. And this data allows the system to augment an environment with the visualization of certain object.
Augmented reality app development company usually performs marker-based tracking in 5 steps:
- image recognition;
- line fitting and detection of the corners;
- discard of foreign objects;
- identification and decoding of the pattern;
- calculation of the pose.
As the result, augmented reality developer can use calculated pose to place an object in the right scale and perspective. And this is the way we get the apps that present virtual objects as a part of reality.
Augmented reality app development: Types of Markers
AR mobile app development company can use a huge number of various marker types to create games and other apps. There are such markers as QR codes, pictures, symbols and patterns.
For example, the most common type is 2D barcode, which is also called QR code. It looks like a combination of black and white cells, which are detected to identify the cell pixel values. Another widespread type, symbols, has a border with a small image inside and consists of binary cells that store necessary data.
Finally, image markers usually use a picture with the natural colors, so they can be a part of real environment, a book cover is an example. Such markers are imperceptible, because they can not be detected by human eye.
Marker-based approach is the simplest way to create interactive augmented reality experience. Despite its simplicity, it is still used to create spectacular applications. One of best marker-based apps is Ikea Catalogue that allows the customers to place the furnishing around a home using devices on iOS and Android platforms.
