Epipolar geometry refers to the mathematical relationship between two images of a scene, taken from two different viewpoints. Some synonyms for this term include stereo geometry, binocular geometry, or simply stereo vision. These terms all describe the same concept of using two cameras to capture images of the same scene, and calculating the geometric relationship between these images. Other related terms include triangulation, 3D reconstruction, and stereo matching. All of these concepts are used in computer vision and machine learning applications to create 3D models of real-world environments and objects. Understanding the principles of epipolar geometry and its synonyms is essential for anyone working in these fields.
