A lot of progress has been made in the field of augmented reality
tracking over the last few years. Several dependable tracking systems
that provide real-time tracking in an indoor setting have been
developed. As previously stated in this survey report, there are still
some challenges with AR tracking, such as occlusion, varying lighting
environments, variable backdrop contrast, and varying color intensities.
The development of algorithms that use marker-based tracking to enable
robust and accurate tracking in a variety of illumination, contrast, and
lighting conditions will be a future focus.
