我正在使用 OpenCV ， Android 和 OpenGL 进行增强现实"项目.据我所知，OpenGL中的协调系统是
I am working with OpenCV, Android and OpenGL for an Augmented Reality project. As far as I know the coordintate system in OpenGL is
OpenCV坐标系为:
The OpenCV coordinate system is:
将这些设备与android传感器结合使用时，如何进行坐标系转换和[R | t]矩阵转换?是否有好的教程或文档对所有这些令人困惑的内容都进行了解释?
When combining these devices with android sensors how can I do the coordinate system conversions and [R|t] matrix conversion? Is there a good tutorial or documentation were all of this conffusing stuff is explained?
推荐答案
如果看图片，您会看到两个坐标系具有相同的手法，但是OpenCV的pi绕x轴旋转了.可以通过以下旋转矩阵来表示:
If you look at the picture, then you see, that the both coordinate systems have the same handednes, but the OpenCV one is rotated by pi around the x axis. This can be represented by the following rotation matrix:
1 0 0
0 -1 0
0 0 -1
