Essential Matrix

The Essential Matrix is a mathematical tool in computer vision that helps determine the relative position and orientation of two cameras observing the same scene. Imagine taking two photos from slightly different angles; the Essential Matrix encodes the geometric relationship between these views. It allows us to find how the cameras are shifted and rotated with respect to each other based on matching points in both images. This is fundamental for 3D reconstruction and navigation, enabling systems like autonomous vehicles or augmented reality to understand spatial relationships from multiple images accurately.
