提出了一种球形摄像球及其图像处理算法，旨在为球类运动的拍摄提供球的视角。所提出的球形摄像机球具有六个摄像机，这些摄像机以固定的间隔嵌入球的表面周围。这种球型摄像机的主要问题之一是设备正在旋转，因此很难从这种旋转的摄像机获得稳定的视频流。提出了一种基于锚帧与当前帧匹配度的摄像机自动选择方法。然后，所得到的电影将始终显示帧内的兴趣点。然后，我们应用图像平移来获得伪直视图，其中感兴趣的点总是显示在帧的中心。
This paper proposed a spherical camera ball and its image processing algorithm, designed to provide a ball's point of view (POV) for spectating of ball sports. The proposed spherical camera ball has six cameras embedded at fixed intervals around the surface of the ball. One of the main issues for such ball-type cameras is that the device is spinning and therefore it is hard to obtain stable video stream from such spinning cameras. This paper proposed automatic selection of cameras using matching scores between the anchor frame and current frame. The resultant movie will then always shows the point of interest within the frame. We then applied image translation to obtain a pseudo straight view in which the point of interest is always shown in the center of the frame.
