【摘要】 沙漠蚂蚁神奇的导航本领为我们研制新型导航传感器提供了有价值的技术参考。分析了沙漠蚂蚁利用天空偏振光分布模式导航的机理,设计了一种新型的仿生偏振测角传感器。提出了一种新的航向角度求解方法,给出了一种基于最小二乘支持向量机航向角输出误差补偿算法。利用精密旋转测试台进行了室外航向角度输出测试,实验结果证明了角度解算方法是可行的,角度误差补偿算法是健壮有效的。更多还原

【Abstract】 According to the mechanisms of polarization sensitivity of desert ant,the bionic angular measurement sensor based on ARM micro-controller was designed.The hardware construction was presented,and a prototype machine was built up.A new angular solution method and a novel angular error compensation algorithm based on LS-SVM(Least Squares Support Vector Machine)were proposed in detail.With the precise rotation table,the navigation angle output experiment is performed outdoor,the result indicates the angular solution method is feasible and the angular error compensation algorithm is effective and robust.更多还原
