Class section ID: 806177
Lecture: TuTh 5:00 PM-6:20 PM, EBU3B 2154
Class discussion: Piazza
This course covers topics in imaging geometry using techniques from
computer vision, photogrammetry, and projective geometry. These
topics include methods for projecting a 3D scene to a 2D image,
reconstructing a 3D scene from 2D images, and camera parameter
estimation. Upon completion of this course, students will have an
understanding of single and multiple view geometry, and the algorithms
used in practice.
Prerequisites: Linear algebra, calculus, probability and statistics.
Matlab, Python, C/C++, or other programming experience.
Assignments should be prepared using LaTeX.

Final project suggestions:
- Estimation of camera pose (camera rotation and translation). Camera rotation is optimized using angle-axis representation.
- Estimation of essential matrix (rotation and translation of second camera relative to first camera). Relative camera rotation is optimized using angle-axis representation and (direction of) translation is optimized using parameterization of the n-sphere.
- Estimation of the trifocal tensor.
- Affine reconstruction using the factorization algorithm.
- Estimation of planar homography from line correspondences.
- Triangulation from line correspondences.
- Estimation of lens distortion parameters and correction of lens distortion.
- Vanishing points and vanishing lines.
- Affine and metric rectification of images.
- Camera calibration (image of the absolute conic).
- Stratified reconstruction of a 3D scene.
- Mosaic construction (2D block adjustment) from video or a set of images.
- Bundle adjustment from video or a set of images.
