The final objective is to develop a pan and tilt camera platform which can control itself to follow and focus on a moving object automatically the same way any living creature watches a moving object through the naked eye. In this research, a pre-defined object is detected and localized from a video stream captured by a camera. Based on the relative position of the object in the image frame, pan and tilt commands are generated by a novel algorithm to track the object. A deep learning approach is used to detect and localize the object from the video stream. Based on its output, the camera is controlled so the object is brought closer to the center of the image frame as much as possible. Using the YOLO-v3 object detection algorithm, a football was tracked with a frame rate of 30fps on Tesla P4 GPU with an average precision of 54%. The camera controlling algorithm works at a frame rate of 7fps with camera movements.
