On account of four distortions such as signal lag, radial distortion, eccentric distortion and thin lens, etc. a precision distortion correction model is established.
新模型考虑了信号滞后、径向、偏心和薄透镜等四种畸变，建立了精确的畸变矫正模型。

The approach is called lead and lagcorrection which has been adopted to correct the stabilization loop of roll-isolated fiber optical gyro strap-down inertial navigation system (RIFOGSINS).
