Selection of partial 3D hulls with normal for the reconstruction of a full 3D hull.

C: camera, R: reference camera. Example frames with partial 3D hulls constructed from 4 cameras (C1 to C4), and frames with full 3D hulls reconstructions (top) are shown. Thick vertical lines indicate times when the frames were captured. Dotted lines connect selected frames for reconstruction of a full 3D hull. The frames were captured while a male was chasing a female.

C代表相机（camera），R代表参考相机（reference camera）。展示了由4台相机（C1至C4）构建得到部分三维凸包（3D hull）的示例帧，以及带有完整三维凸包重建结果的示例帧（对应顶部图像）。粗竖线标示帧的拍摄时刻，虚线连接用于完整三维凸包重建的选定帧。所有帧均拍摄于一只雄性个体追逐雌性个体的过程中。
