OpenCV 错误 : Bad argument <Unknown array type> in unknown function, 文件 ..\..\..\modules\core\src\matrix.cpp，第 697 行

Question

我目前正在尝试纠正立体相机以创建视差图。不幸的是，我无法通过立体声校正步骤，因为我一直收到错误

"OpenCV Error: Bad argument in unknown function, file ..\..\..\modules\core\src\matrix.cpp, line 697."

这个过程很复杂，因为我不是校准相机的人，也无法访问用于录制视频的相机。我获得了所有校准参数(内在参数、失真系数、旋转矩阵和平移向量)。如您所见，我尝试将它们直接转换为 CvMats 并以这种方式使用它们，但是当我尝试实际使用它们时出现错误。

提前致谢。

所以，您被 c-api 咬伤了吗？你为什么不背对它呢？

尽可能使用 c++ api，请不要从旧的(1.0)、已弃用的 api 开始学习 opencv!
