Structure from Motion
3-D reconstruction from multiple views
Structure from Motion (SfM) is the process of estimating the 3-D structure of a scene from a set of 2-D images. For more details, see Implement Visual SLAM in MATLAB.

Basics
- Coordinate Systems
Specify pixel Indices, spatial coordinates, and 3-D coordinate systems. - Point Feature Types
Choose functions that return and accept points objects for several types of features. - Local Feature Detection and Extraction
Learn the benefits and applications of local feature detection and extraction. - What is Structure from Motion?
Estimate three-dimensional structures from two-dimensional image sequences.
Apps for Camera Calibration
- Using the Single Camera Calibrator App
Prepare camera calibration images and estimate camera intrinsic parameters. - Using the Stereo Camera Calibrator App
Calibrate a stereo camera, which you can then use to recover depth from images.
