description: The given work is devoted to the research of disparity map estimating, which can be used in others computer vision tasks, such as reconstruction scene in 3D space, image segmentation. The research sets the following goals: â¢ Studying the process of obtaining stereopair images from stereovision system. â¢ Review some disparity map estimation algorithms. â¢ Research ELAS algorithm as promising for optimization for using on graphic accelerators. â¢ ELAS algorithm modification with CUDA for using on Graphic Processing Units and further approbations. Modifications of several algorithm stages were developed which can be done on graphic accelerators with observed computational performance increasing. During a series of experiments with using specialized dataset were showed that disparity map quality is close to ground truth.
