AR CityAR Cities, or Augmented Reality Cities, are cities that are merge the digital and phycical realms through digital technologies, such as digital twins.
AR Cities combine key aspects of Augmented Reality (AR) and Computer Vision (CV) to change the way we perceive our cities as we walk and explore them. This technology has the potential to eventually replace existing mapping systems.

AR Projection Mapping
AR Projection Mapping is the process of using a projector to illuminate surfaces with any structure. The image plane of the projector already contains the individual characteristics of the surface structure to be illuminated. The use of a precisely fitting template in the image plane of the projector is the basic prerequisite for projection mapping. Such a template can be created by calculation (using photographs) or by tracing the surface structures through the projector, for which special techniques are used.
Static and Dynamic Projection Mapping
Projection mapping is possible with all types of projectors. Depending on the reproduction characteristics of the projector, a distinction is made between static and dynamic image content.
Static projection mapping
Static projection mapping is implemented with projectors that can reproduce still images (photos), such as slide projectors and overhead projectors. The precisely fitting template is contained in the image plane (film, slide). The precisely fitting still images are then projected onto the predefined surface.
Dynamic projection mapping
Dynamic projection mapping is implemented with projectors that can reproduce image sequences, in most cases with video projectors. In this case, the precisely fitting template is contained in the file that is output via the imaging layer of the video projector. The precisely fitting image sequences are then projected onto the predefined surface.
ARTag is a system of reference markers to support augmented reality. They can be used to facilitate the appearance of virtual objects, games and animations in the real world. Like the earlier ARToolKit system, they enable video tracking capabilities that calculate camera position and orientation relative to physical markers in real time. Once the camera's position is known, the virtual camera can be positioned at the same point, revealing the virtual object at the ARTag location. It thus solves two key augmented reality problems: point-of-view tracking and interaction with virtual objects.
ARTag appears in the Mars Science Laboratory. A similar method is used in NASA's smartphone app Spacecraft 3D as an educational tool.
ARTag is supported by Goblin XNA open source software.
