TRILATERATED PHOTO COORDINATES

A METHOD IS PRESENTED WHEREBY PHOTO COORDINATES MAY BE OBTAINED USING INEXPENSIVE APPARATUS IN CONJUNCTION WITH TRILATERATION COMPUTATIONAL TECHNIQUES AND AN ELECTRONIC COMPUTER. THE METHOD TAKES ADVANTAGE OF REDUNDANT MEASUREMENTS AND CONSEQUENTLY IT MAKES POSSIBLE THE CALCULATION OF THE MOST PROBABLE VALUES OF THE PHOTO COORDINATES AS WELL AS THEIR ESTIMATED STANDARD DEVIATIONS. THE METHOD HAS BEEN TESTED USING A SIMPLE GLASS SCALE AND THE RESULTS INDICATE AVERAGE ESTIMATED STANDARD DEVIATIONS IN X AND Y OF APPROXIMATELY FIVE MICRONS. THESE RESULTS ARE NOT AS ACCURATE AS THOSE POSSIBLE WITH A PRECISE COMPARATOR. THE METHOD DOES, HOWEVER, PROVIDE UNUSUALLY GOOD RESULTS IN RELATION TO COST AND IT ALSO PROVIDES SEVERAL SIGNIFICANT ADVANTAGES OVER OTHER LOWER ORDER PROCEDURES. /AUTHOR/
