| 摘 要： | 针对惯性测量单元(IMU)基准面与载体平台之间的标定,在通过基准面法向量建立惯性测量单元基准面坐标系与载体平台坐标系的基础上,研究并分别比较利用单台全站仪角度交会及摄影测量技术的标定方法,以实现IMU与载体平台之间快速、方便以及高精度的标定。通过标定实验及误差分析表明,摄影测量标定精度高,时间短,稳定性好,更适合应用于IMU和载体平台安装后的标定工作。

| Abstract: | For the calibration of Inertial Measurement Unit(IMU) datum and the carrier platform ,on the basis of the IM U datum ,a coordinate system and a carrier platform coordinate system are established by the normal vector of reference plane . T he use of a single total station angle intersection and photogrammetry techniques calibration method is studied and compared in order to realize a fast , convenient and high precision calibration between the IMU and the carrier platform . Calibration experiments and error analysis show the photogrammetry calibration with higher precision , more efficiency ,better stability ,and more suitable for the calibration work between IMU and carrier platform . |
