Computing Fundamental Matrix and Drawing Epipolar Lines for Stereo Vision Cameras in OpenCV

Following my other post, you can extract the equation for epipolar lines. Basically choosing one point in one image and using fundamental matrix, we will get a line in the other image:


Creating a Simulated Stereo Vision Cameras With OpenCV and C++

n this tutorial, I created an ellipsoid in 3D space and create two cameras in right and left and captured the image:​
