                         development of Virtual Reality (VR) and Augmented Reality (AR) 
                         applications, using natural markers for industrial scenarios. The 
                         proposed methodology uses the object annotation concept and 
                         visualization proposals are presented both for development of VR 
                         as for AR environments. In VR environments, the methodology is 
                         applied for object detection step of the semi-automatic authoring 
                         tool. On the other hand, in AR environments, is presented the 
                         concept of georeferenced natural markers, which use the 
                         georeferenced data integrated with object detection process using 
                         image processing techniques. The energy substations scenarios were 
                         used as case study for both approaches. This work proposes using 
                         Haar-like feature based natural markers integrated with 
                         homomorphic filtering for object training and detection process. 
                         The results enable the equipment detection at different points of 
                         view, within the operating scenario. Besides that, in AR, it 
                         enables the pose estimation in real-time using ORB features, while 
                         in VR it enables the semi-automatic object detection, which are 
                         used as information points for inclusion of virtual information. 
                         Several industrial scenarios, and especially the energy sector, 
                         has a high degree of complexity in the information processing and 
                         visualization. In this sense, beyond the 3D natural markers 
                         methodology, this work presents visualization applications for 
                         industrial scenario visualization in VR and AR approaches.",
