开放CV 校准参数和从定型观念照相机转变3点
原标题:OpenCV calibration parameters and a 3d point transformation from stereo cameras

I ve 4 ps3eye cameras. And I ve calibrated camera1 and camera2 using cvStereoCalibrate() function of OpenCV library using a chessboard pattern by finding the corners and passing their 3d coordinates into this function.

另外,我还使用另外一套摄像机板图像,照相机2和照相3,对摄像机进行校准。

采用同样的方法,我对照相机3和照相4。

So now I ve extrinsic and intrinsic parameters of camera1 and camera2, extrinsic and intrinsic parameters of camera2 and camera3, and extrinsic and intrinsic parameters of camera3 and camera4.

外部参数是轮换和翻译的矩阵,其内在性质是重点长度和原则点的矩阵。

现在,有人看着一个3d点(世界协调)(我知道如何从陈规定型照相机找到3个坐标),而照相3和照相4则不为照相1和照相2。

The question I ve is: How do you take this 3d world coordinate point that is viewed by camera3 and camera4 and transform it with respect to camera1 and camera2 s world coordinate system using rotation, translation, focus and principle point parameters?

最佳回答

开放式磁体的校准只给你relative外在两部照相机之间穿透矩阵。

根据其文件,你没有在世界坐标(即与校准模式有关的)进行变革。 它建议对图像之一定期进行摄像校准,至少知道图像的转变:

如果校准是完美的,你就可以利用你建立的达伊-链,使任何照相机的世界转变。

我知道这一点并不稳定,因为你有多个摄像机,在进行校准时应考虑这一事实。

多功能校准并不是最棘手的问题。 审视:

我也希望找到解决办法,这样,如果你能够更多地了解这一点,那么,我知道开放世界会。
