A mathematical model for the simulation of a photogrammetric camera using stellar control

A mathematical model that simulates a camera and its orientation in inertial space is described. Also, a computer program that utilizes this mathematical model and least squares techniques to estimate camera orientation parameters from measured coordinates of star images is presented. Although the primary purpose of the computer program is for application in a world-wide geometric satellite triangulation system, sufficient flexibility has been incorporated to allow its use as a photogrammetrist tool for precision camera calibration. 1972 NOS (National Ocean Service) Library Public domain 1936
