Nonmagnetic inertial navigation unit calibration method based on image measuring technologies

The invention relates to a nonmagnetic inertial navigation unit (IMU) calibration method based on image measuring technologies. A specialized nonmagnetic calibration frame, a geological compass and more than two vidicons are placed in a measuring environment. The space coordinate of the geological compass and the coordinate of the indication ball of the calibration frame of the image measuring analytic system are measured respectively by utilization of a total station, and a unified measuring coordinate system is constructed. An IMU to be measured is fixed on the frame. In the measuring frame, two white and reflective balls are arranged at each of three orthogonal directions of X, Y and Z and used for indicating axial directions. The measuring frame is revolved continuously around the X, Y and Z axes. The corresponding dynamic images are collected synchronously through the vidicons and the data output from the IMU is recorded at the same time. The indication ball space coordinate data is calculated through the mage measuring analytic system, and then the space attitude data of the frame is figured out and used as theory data. Through comparison of the theory data and the space attitude data output from the IMU, the error of the IMU is calculated, and finally the correction coefficient is obtained by utilization of the least square method.
