生物能够进行偏振光导航定位,一方面是其本身具有对太阳光偏振方向极其敏感的视觉神经系统,另一方面是天空中存在一个可供感知的大气偏振光模式图。对天空偏振模式图进行理论上的分析,研究天空偏振模式图的相对稳定性,再利用仿生偏振导航传感器单体进行实际测量定标,对其进行精度分析得到误差纠正公式,为将来多单体导航提供理论基础,也为导航的实际应用提供参考。
Many animals are able to use sky polarized light for navigation. They have a visual nervous system which is extremely sensitive to the sky polarized light, and there exists a perceptible polarization distribution in the sky. Intending to analyze the accuracy and the error correction formula, trying to figure out the sky polarization mode figure theoretically, and then studied on the relative stability of the sky polarization mode figure, and completed the measuring and calibration using the bionic polarization navigation sensor. This research will make the foundation of the navigation with multiple sensors and provide the reference for the practical application.
