Design Study of a Light Module for a Photogrammetric Camera Calibration Range
Abstract
A design study of a light module for a night photogrammetric camera calibration range was performed. It was determined that a ground-based light could be developed to serve as a near pin-point-size object that would be imaged upon the film of an overflying aerial camera and be measurable to an accuracy of 3 microns r.m.s. Such a light would be installed at each grid point of a camera calibration range at Casa Grande, Arizona, and would provide the DOD with a night capability for camera calibration with an expected improvement in accuracy. It was determined that the light source would be a low energy (2.5 joule), pulsed, xenon flash lamp with provisions for synchronization, and remote control from either the aircraft or a ground station.
