3-D Vision

Extract 3-D information from 2-D images

Start Here

3-D vision is the process of reconstructing a 3-D scene from two or more views of the scene. Using the Computer Vision System Toolbox™, you can perform dense 3-D reconstruction using a calibrated stereo pair of cameras. You can also reconstruct the scene using an uncalibrated stereo pair of cameras, up to unknown scale. Finally, you can compute a sparse 3-D reconstruction from multiple images, using a single-calibrated camera.


disparity Disparity map between stereo images
epipolarLine Compute epipolar lines for stereo images
