Kohdepintaan

Kohdepintaan is a Finnish term used in technical contexts to describe the action or result of projecting data onto a target surface or plane. In practice, it denotes transforming coordinates or measurements from one reference frame onto a predefined surface designated as the target.

Etymology and usage notes: The compound combines kohde (target) and pinta (surface), with the suffix that conveys direction toward or onto the surface. The term appears mainly in Finnish technical literature and is less common in everyday language, where English equivalents such as “projection onto the target plane” are more frequently used.

Applications: In computer graphics and computer vision, kohdepintaan refers to projecting a 3D point onto a defined target plane to obtain 2D coordinates or to align data. In robotics and metrology, it describes mapping sensor measurements or geometric features onto a reference plane for analysis, calibration, or planning. In photogrammetry, the concept is used when transferring measurements to a ground or sensor plane for interpretation.

Variants and standardization: The noun phrase kohdepintaan can appear in compounds such as kohdepintaan-projekointi (target-plane projection) or kohdepintaan siirtäminen (transfer to the target plane). The term is not universally standardized, and translations into English typically use “projection onto the target plane” or “onto-plane projection.”
