PHOTOGRAMMETRY SYSTEM AND PHOTOGRAPHING CONDITION DETERMINATION METHOD FOR PHOTOGRAMMETRY

摘要

PROBLEM TO BE SOLVED: To provide a photogrammetry system in which photogrammetric simulation is performed and a photogrammetric point and a photographing condition for accurately performing photogrammetry can be evaluated beforehand, and a photographing condition determination method for photogrammetry.;SOLUTION: A photogrammetry system and a photographing condition determination method for photogrammetry are obtained in which a temporary measurement point 7 is set to a measurement target model 61 which is created on a 3D CAD space 31 and a shape around that point is analyzed, thereby selecting a logical measurement point extraction processing method for extracting a logical measurement point for accurately performing photogrammetry around the temporary measurement point 7. The logical measurement point obtained by performing temporary photogrammetry according to this method is compared with design data to determine whether desired measurement precision can be obtained. Thus, a photographing position/direction suitable for actual photogrammetry can be acquired.;COPYRIGHT: (C)2013,JPO&INPIT
