How can i obtain Camera Matrix in 3Dreconstruction?
You already have a code for camera calibration and printing a camera matrix in your OpenCV installation. Go to this path if you are on windows -
C:\opencv\sources\samples\python
There you have  a file called calibrate
I want to achieve a 3D-reconstruction algorithm with sfm,
But how should i set the parameters of the Camera Matrix?
I have double cameras,both know their focal length.
And how about Rotation Matrix and Translation Matrix from world view?
i use python
