3B sanal ortamlarda algıya dayalı stereoskopik kamera kontrolü

Depth notion and how to perceive depth have long been studied in the field of psychology, physiology, and even art. Human visual perception enables to perceive outside world by using visual depth cues. Binocular disparity among these depth cues, is based on the separation between two different views that are observed by two eyes. Disparity concept constitutes the base of the construction of the stereoscopic vision. Emerging technologies try to replicate disparity principles to provide 3D illusion. However, complexity of applying the underlying principles of 3D perception, confronted researchers the problem of wrongly produced stereoscopic contents. In this work, we present a camera control mechanism: a novel approach for disparity control and a model for path generation. We address stereoscopic 3D production by presenting comfortable viewing experience to users. Therefore, our disparity system approaches the accommodation/convergence conflict problem, which is the most known issue that causes visual fatigue in stereo systems, by considering objects' importance. Stereo camera parameters are calculated automatically with an optimization process. In the second part of our control mechanism, the camera path is constructed for a given 3D environment. Moving around important regions of objects is a desired scene exploration task. In this respect, object saliencies are used for viewpoint selection around scene elements. Selected viewpoints are linked in the form of Bezier curves to generate path structure. Our method and existing two other disparity control models are compared with user studies. Results indicate that our method shows superior results in quality, depth, and comfort.
