The comparison of photogrammetric performance of two kinds of space‐borne three‐line array cameras

Abstract

Purpose

To improve the accuracy of mapping of space‐borne three‐line array cameras.

Design/methodology/approach

Derivation of the mathematical model and the error model of the three‐line aerial triangulation, the creation of the simulation data, and the analysis and comparison of the simulating result error.

Findings

When using the photographs, which are acquired by adopting the traditional three‐line array cameras, to map without control, there exists the problem that the accuracy cannot satisfy the requirement.

Research limitations/implications

Do not need the ground control points, and can realize the mapping without control. It is of practical application value to the mapping of stars such as the Moon, Mars.

Practical implications

By adding four small matrix CCDs to the traditional three‐line array cameras, and using the effect of the small matrix, controlling the location of the real photograph point, it can improve the accuracy.

Originality/value

Put forward the LMCCD concept of the combination of the three‐linear and the matrix cameras, and validate in theory.
