Hello Sorry for the bombardment of posts, but I want to share some stuff I've been working on lately, so when I find time I just shoot the posts out. So this time I'll talk shortly about how to get an estimation of a rigid transformation between two clouds, that potentially are also of different […]

Hiya Just catching up on some bloggin, and I wanna share a snippet of OpenCV code on how to check if your (badly) triangulated 3D points came up co-planar, and therefore a botch triangulation. It's a very simplistic method, only a few lines, and it also is part of my Structure from Motion Toy Library […]

Hello This time I'll discuss a basic implementation of a Structure from Motion method, following the steps Hartley and Zisserman show in "The Bible" book: "Multiple View Geometry". I will show how simply their linear method can be implemented in OpenCV. I treat this as a kind of tutorial, or a toy example, of how […]
