| 摘 要： | 地磁导航应用中常采用插值运算来提高地磁图的精度,但目前常用的地磁图插值方法都存在计算复杂、不适于实时解算等缺点。提出用双线性插值方法进行地磁图插值,该方法原理简单、计算量小,且适于在微处理器上实时解算,为地磁导航的工程实现提供了参考。

| Abstract: | Interpolation method is usually applied to improve the precision of geomagnetic map in geomagnetic navigation.However,the actual interpolation methods all have disadvantages,such as being complex for calculation, not fitting for real time solution,and so on.Therefore,the bilinear interpolation is proposed in this paper,with simple principle,less calculation,and easy realization on MPU,which is valuable and feasible in engineering application for geomagnetic navigation. |
