NUMERICAL APPROACH FOR ANALYZING CRITICAL CONFIGURATIONS OF SINGLE PHOTO RESECTION

摘要

Single photo resection for estimating exterior orientation parameters can be achieved by using control points, control lines, or effective control data of other types. However, orientation solution would become largely uncertain or even impossible to solve when faced with poor layout of control data. This study mainly focused on identifying such geometrically configurations when employing point features and line features. The authors utilized rank analysis together with condition number to spatially locate the area of control points and control lines that fall into singular solutions. Consequently, effective observations toward a satisfactory solution can be then arranged.
