本文提出了四种仅使用单张未校准图像的新平面估计方法。众所周知，一幅图像不能提供足够的三维信息，但利用点的平面性、直线与平面的平行性等几何线索，可以直接从这幅图像中估计出一些测量量。特别是本文利用四种新的几何线索来估计一个特定的艾德空间平面，第一种是平面上的已知长度，第二种是平面上的已知角度，第三种是平面上的真圆及其圆心位置，第四种是平面上的两个圆或两个平行圆.此外，我们估计几个3D实体，如两个空间点之间的距离从单个图像通过使用估计的平面。使用一些真实的图像的实验验证了艾德，我们的方法提供了良好的三维信息。
In this paper, we propose four new plane estimation methods using only single uncalibrated image. It is well known that only one image cannot provide enough 3D information, but some metrical quantities can be estimated directly from the single image by using geometrical clues such as planarity of points and parallelism of lines and planes. Speci(cid:12)cally in this paper, we utilize four new geometrical clues to estimate a speci(cid:12)ed space plane; the (cid:12)rst is known length on the plane, the second is known angle on the plane, the third is true circle and its center position on the plane, and the last is two circles on the plane or its parallel ones. Furthermore, we estimate several 3D entities such as a distance between two space points from the single image by using estimated planes. Experiments using some real images veri(cid:12)ed that our methods give good 3D information.
