Question

I m using OpenCV 2.2 and I m trying to calibrate two cameras to view along the same co-ordinate system. The two cameras will be placed a little separate from each other. I understand calibrating intrinsics for a single camera, but am a little confused so as to how I d be able to combine two cameras together. Follow up questions are good too.

Answer 1

可在上? 我的回答是:StereoCalibrate,将使你能够解决你可以用来把任何一点照相机点与另一个照相机点联系起来的基本矩阵。

Answer 2

The fundamental matrix F defines the relation between the two cameras, that means given an image point x1 in C1 how it constrains the position of the corresponding point x2 in C2. The answer: x1 defines a line in C2 and x2 must be on this line. That is epipolar geometry. It is defined just by the cameras parameters and it does not depend on the scene geometry at all.
现在,你有2个预测矩阵、P1和P2,即,你知道两个照相机的所有参数。如果您有correspondences, x1 <-> x2 (x1 from C1 and x2 from C2),你就可以估算在C1和C2中被图像成x1和x2的空间中X点的3D位置。您能够重建你的芭蕾舞厅/乐团,获得3D模式。 trick部分是找到对应的x1 <->x2。

现在,如果你要知道C1和C2是否看到同样的话,那么你的问题可能不是stereo problem,而是 承认问题<>。 Maybe SIFT或算法是一种更为恰当的方法。
