Camera Pose Estimation from Vanishing Points
I want to estimate the pose of camera (Location and Orientation). Can I use Vanishing Points to get the location and orientation of the camera?
There is object in the image which I also know his size,...

Extrinsic Camera Parameters without introducing control points?
I am new to the field of Camera Calibration. We have successfully calibrated our camera through classic method (using checkerboard etc).
I recently realized there is a field of research for Automatic ...

How are the scaling parameters included (extracted from) an essential matrix?
An essential matrix relates corresponding points between two images assuming that a camera satisfies the pinhole camera model, and can be expressed as:
$$E=K'^TFK$$
where K is the calibration and F ...

Obtain motion between image features by means of the homography matrix
I have been reading several really good answers about how to obtain camera pose (rotation, translation, etc), such as this one and this one, but I am not sure how this applies to my problem.
My ...

Does accurate translation estimation using a camera matrix mean the orientation estimation will also be accurate?
Pose Estimation of single camera and planar pattern:
If I have an appropriate camera matrix with intrinsic parameters that allows me to calculate translation of the camera relative to a chessboard, ...

Can you average out focal length from different camera calibration sessions?
If I perform a number of camera calibration routines at a fixed resolution, with various sizes of calibration patterns (like checkerboards), at various distances and get various values for focal ...
