Abstract:
Spatial triangulation employing two or more fixed cameras which record the same flash event is used to determine the precise position of a vehicle or missile-borne flash. The triangulation procedure requires that the position and calibration of the cameras used must be accurately known. An accurate position may be found by survey. The cameras are fixed phototheodolites with electronic shutter control. Since they are employed at night, the star backgrounds recorded on the camera plates provide an excellent means of obtaining precise analytical calibrations by a method known as star calibration. The formulas for this method calibration as programed for the I.B.M. 7090 computer are presented. Briefly, the program uses the camera dial settings, the times of the exposures, and the measurements of the star images on the plate to identify the stars automatically and execute a least squares solution to obtain an essentially error-free camera orientation calibration.
