epäpolarisuus
Epäpolarisuus (epipolarity) is a term used in the context of satellite imagery, remote sensing, and photogrammetry to describe the geometric relationship between objects and their projections in different images. It refers to the concept that, when viewing a three-dimensional scene from multiple viewpoints, corresponding points in overlapping images lie along specific geometric lines called epipolar lines. This principle is fundamental for processes such as stereo image analysis, 3D reconstruction, and image matching.
The epipolar geometry is governed by the relative positions and orientations of the imaging sensors or cameras.
Epäpolarisuus is essential in various fields, including cartography, geology, and environmental monitoring, as it helps improve
In practice, the concept is applied through the calibration of cameras, the correction of image distortions,
Overall, epäpolarisuus is a key aspect of spatial image analysis that facilitates the extraction of three-dimensional
