From Image to 3D: The Structure from Motion in OpenCV

We capture the world with cameras that compress depth, texture, and geometry into flat pixel grids, yet our minds effortlessly reconstruct the 3D structure behind them. What if computers could do the same? Structure-from-Motion (SfM) is the technique that enables this. By analyzing how features shift across multiple images, SfM simultaneously recovers the camera motion and the scene’s underlying 3D shape, effectively “lifting” depth from 2D photographs.
