I run simple test for OpenCV camera pose estimation. Having a photo and the same photo scaled up (zoomed in) I use them to detect features, calculate essential matrix and recover camera poses. Mat...

I have two sets of corresponding points from two images. I have estimated the Essential matrix which encodes the transformation between the cameras: E, mask = cv2.findEssentialMat(points1, points2...

In my mind they both mean reconstructing 3D coordinates from matched points in 2D images. What's the difference between these concepts and multi-view stereo? Which one do you call an algorithm tha...

Under the assumption that the camera model is orthographic, how do orthographic and perspective camera models in structure from motion? Also, how do these techniques differ from each other?

I'm a dev with about a decade of enterprise software engineering under his belt, and my hobbyist interests have steered me into the vast and scary realm of computer vision (CV). One thing that is ...

Assume I have good correspondences between two images and attempt to recover the camera motion between them. I can use OpenCV 3's new facilities for this, like this: Mat E = findEssentialMat(imgp...
