Surveying Glossary — Letter I

An algorithm used in surveying and 3D data processing to align two point clouds by iteratively finding the closest points and calculating optimal transformation parameters.

ICP (Iterative Closest Point) is a fundamental algorithm used in surveying and 3D point cloud registration to align two datasets by iteratively matching corresponding points and minimizing the distance between them.
