Interest in motion capture (mocap) technology is growing every day, and the number of possible applications is multiplying. But such systems are very expensive and are not affordable for personal use. Based on that, this thesis presents the framework that can produce mocap data from regular RGB video and then use it to animate a 3D character according to the movement of the person in the original video. To extract the mocap data from the input video, one of the three 3D pose estimation (PE) methods that are available within the scope of the project is used to determine where the joints of the person in each video frame are located in the 3D space. The 3D positions of the joints are used as mocap data and are imported to Blender which contains a simple 3D character. The data is assigned to the corresponding joints of the character to animate it. To test how the created animation will be working in a different environment, it was imported to the Unity game engine and applied to the native 3D character. The evaluation of the produced animations from Blender and Unity showed that even though the quality of the animation might be not perfect, the test subjects found this approach to animation promising. In addition, during the evaluation, a few issues were discovered and considered for future framework development.
