Frontoparallel

Frontoparallel is a term used in the fields of computer graphics, computer vision, and photogrammetry to describe a plane that is parallel to the image plane of a camera or sensor. This concept is crucial for understanding the geometry of image formation and is often used in the calibration and rectification of cameras. In a frontoparallel plane, the orientation of the features or objects within the image is preserved, meaning that the angles and distances between points are accurately represented. This is in contrast to other orientations where distortions may occur due to perspective effects. Frontoparallel planes are particularly useful in applications such as 3D reconstruction, where maintaining the geometric integrity of the scene is essential. The term is derived from the Latin words "frontalis," meaning "front," and "parallelus," meaning "parallel," reflecting the relationship between the plane and the image plane. Understanding frontoparallel planes is fundamental for accurate image analysis and the development of robust computer vision algorithms.
