| Abstract: | In the production of IMU/DGPS supported photogrammetry,some issues photogrammetric professionals are mostly concerned about,such as: What is the purpose of a calibration field? How to design it? How often should calibration be performed? And what are the requirement criteria for calibration? Those questions are answered by analyzing the functions of a calibration field,presenting the design scheme of calibration field,and carrying out a lot of experiment about it. |
