The 3D reconstruction can be employed in several areas such as markerless augmented reality, manipulation of interactive virtual objects and to deal with the occlusion of virtual objects by real ones. However, many improvements into the 3D reconstruction pipeline in order to increase its efficiency may still be done. In such context, this paper proposes a filter for optimizing a 3D reconstruction...
Nowadays, underwater maintenance tasks, mostly in the case of oil and gas industries, have been assisted by computer vision algorithms. An important part of these procedures is the rectification of stereo images, which is the first step in the stereo 3D reconstruction pipeline. Some aspects of the underwater environment make the rectification process difficult: it presents a very noisy scenario; and...
This paper presents a solution for the photorealistic rendering of synthetic objects into dynamic real scenes, in Augmented Reality applications. In order to achieve this goal, an Image Based Lighting approach is used, where environment maps with different levels of glossiness are generated for each virtual object in the scene at every frame. Due to this, illumination effects, such as color bleeding...
