提出了一种快速标定光纤陀螺仪关键参数的方法,利用激光连续动态弯沉测量车自身的硬件平台,建立以光纤陀螺仪标度因素、零偏与输出延时为参数的数学模型,采用改进的最小二乘法进行求解,完成上述关键参数的快速标定。该方法标定过程简单快速,标定结果精度高,已成功应用在武汉大学研制的我国首台激光连续动态弯沉测量车中。 A method of rapid calibration of key parameters of fiber optic gyroscope is proposed. By using the laser to dynamically deflect the hardware platform of the measuring car, a mathematical model based on the scaling factor, zero bias and output delay of fiber optic gyroscope is established. The least squares method to solve, to complete the rapid calibration of the key parameters. The calibration method of the method is simple and fast, and the calibration result has high precision and has been successfully applied in the first laser continuous dynamic deflection measurement vehicle developed by Wuhan University.
