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:

RGBD PCL point cloud from Stereo vision with ROS and OpenCV

In my other tutorial, I showed you how to calibrate you stereo camera. After Calibration, we can get disparity map and  RGBD PCL point cloud from our stereo camera cool huh 🙂 1)Save the following text under “stereo_usb_cam_stream_publisher.launch”

2) Then run the following node to publish both cameras and camera info (calibration matrix)

3) Run the
