2016-01-16 13:50:17 -0600 | asked a question | How to get real world 2D coordinates of rectified pixels? Hello,
I have a system with a camera looking vertical on a table and there is a robot with a target. I already have the camera calibrated and i have the extrinsic and intrinsic values and get a rectified image.
Now i compute the mass center of the target and get its values My question now is how do i get the real 2D (x,y) world coordinates? I don't need the z value because it has always the same z value (10 cm). Could anyone explain it to me please? |

I'm tracking a target and get the mass center with contours() and moments() method and if i want i can get float values of them. But why is this even possible? An image can't have a 0.1234 Pixel. Can anybody explain this to me please? |

Hello, i want to know how i can find the pixel postion of the corner points of a rectangular contour? With Or even better is there a possibility to find the the angular orientation of the rectangle? Please help it's important for me. |
