This can be done using computer vision technique and from symmetry property of potteries. The problem of recovering the 3D shape of a surface of revolution from images is addressed. The algorithm makes use of the symmetry properties of a surface of revolution and its silhouette to rectify the image such that the resulting silhouette exhibits bilateral symmetry.

在该方法的实现过程中，首先利用旋转平台获取了旋转体的影像，然后基于物方的空间圆重建方法精确测量旋转体的上口，从而得到旋转体的旋转轴，再根据影像的方位元素对影像进行纠正，使得旋转体的轮廓线在影像上的成像左右对称，最后直接用纠正后的影像精确计算旋转体的形状。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
