ANALYTIC BLOCK ADJUSTMENT

THE COMMISSION III WORKING GROUP CONSISTED OF PARTICIPANTS FROM CANADA, FINLAND, GERMANY, JAPAN AND THE UNITED STATES WITH A TOTAL OF 12 ORGANIZATIONS BEING INVOLVED. DURING THE PERIOD 1968-72, EACH PARTICIPANT OF THE GROUP PERFORMED INDEPENDENT ADJUSTMENTS OF A 5 X 20 BLOCK OF SIMULATED NEAR-VERTICAL PHOTOGRAPHY, HAVING AN APPROXIMATE SCALE OF 1:66,000. METHODS USED WERE: (A) SIMULTANEOUS ADJUSTMENT OF PHOTOGRAPHS (BUNDLE ADJUSTMENT); (B) SIMULTANEOUS ADJUSTMENT OF INDEPENDENT MODELS; AND (C) SEQUENTIAL POLYNOMIAL ADJUSTMENTS. A SINGLE BLOCK SIZE AND UNIFORM CONTROL ARRAYS WERE SPECIFIED ALLOWING REALISTIC COMPARISONS. THE BUNDLE ADJUSTMENTS PRODUCED THE MOST ACCURATE RESULTS AT A HIGHER COST THAN SIMULTANEOUS ADJUSTMENT OF INDEPENDENT MODELS AND THE POLYNOMIAL ADJUSTMENTS.
