AR X-Ray : Portable Projector-based Augmented Exploration of Buildings

Fábio R. de MirandaRomero ToriCláudio E. S. BuenoLucas P. Trias

This paper presents the design and implementation of AR X-Ray, an augmented reality tool that allows visual exploration of internal details of buildings (such as pipes and ducts) through the use of a portable projector that works as a "magic lantern" that projects a Virtual X-Ray over real walls. Results and details regarding solutions for technical problems are discussed. Some of the addressed issues are projector tracking, proper registration of synthetic information over real objects and the development of a shader that manipulates the transparency of textures to allow the user to view what is behind objects.
