TRACKING AND RENDERING IMAGES IN THE CONTEXT OF AUGMENTED REALITY USING A SMARTPHONE
Augmented reality (AR) is a concept that was introduced in the 60s of the 20th century, but no major AR applications have appeared since. This was mainly due to the hardware and software requirements of AR, but the situation has changed in the recent past, with the success of smartphones. Modern smartphones are equipped with all the necessary equipment, as well as sufficient computing performance to track markers and visualize objects for augmented reality. Currently, there are several different types of tracking markers to achieve the effect of augmented reality. This article discusses the following options for tracking markers: non-visual tracking, visual tracking, and visual tracking without markers, which combines both approaches. The process of image rendering is considered. An example of a technology that allows you to achieve a photorealistic image, as well as a technology for rendering images in real time. The comparison of current technologies shows that the achievement of photorealistic image rendering in real time is not yet possible due to insufficient computing power, but thanks to the development of the Vulkan API, this feature may appear in the near future.
