| 摘 要： | 针对航空用线状目标的矢量地图匹配问题，提出了一种多层次约束的矢量地图匹配导航算法（MLC-VMMA）.该算法利用差角作为线状目标的匹配特征量，依次根据距离、顺序和误差等多层次约束条件来减小可行解空间的大小，完成在具有旋转、平移、缩放变换下的矢量地图匹配.仿真结果表明，MLC-VMMA适用于小尺度缩放变换下的矢量地图匹配，具有较高的可靠性与导航精度.

| Abstract: | To solve the aerial vector map matching problem for linear objects, a multi-level constrained vector map matching navigation algorithm (MLC-VMMA) was proposed which used the difference angle as the matching feature for linear target. The MLC-VMMA reduces, in turn, the size of feasible solution space with multi-level constraints including the distance constraint, the order constraint and the error constraint. The MLC-VMMA can solve the vector map matching problem in rotation, translation and scaling transformation. Simulation results show that the MLC-VMMA has a high reliability and navigation accuracy, even for vector map matching in small scaling transformation. |
