我有一个camera和一个3D对象，我计算了this中给出的camera matrix。使用相机拍摄的图像尺寸为1600x1200.但是在相机矩阵中，我没有正确获得图像centers的值。而不是800, 600我得到了一些其他的价值观。可能的原因是什么。

答案 0 :(得分：1)
编辑：
我已经拍摄了你提供的3D坐标点之一，然后尝试在虚拟相机上投影它们（以防止任何与3d-2d点对应的错误）。在这种情况下，正确估计了alpha，beta和gamma，但是u和v（你正在寻找）在我的所有实验中出于某些原因都是负面的。也许我的代码中存在一个错误，但这可能是由于OpenCV solveZ实现的不准确（我之前遇到过OpenCV的特征值/向量计算问题，并且在需要高精度时尝试使用OpenBLAS）。
另一个可能的原因 - 正如作者所述，这种方法执行代数最小化，这可能产生无意义的物理结果。也许您应该检查剩下的部分纸张或尝试不同的方法。
这是更新后的代码：
