| 中文摘要 | 对自身位置与方向的感知是人类各种活动的基础。由此发展而来的导航定位技术逐渐成为人类生存与进一步发展的基础。随着科学技术与国民经济的不断发展，导航定位技术的重要性越来越突出。它的应用已经渗透到现代社会每一个领域。伴随着导航定位技术的发展，人类活动范围不断扩大，从陆地走向海洋，从地面走向天空，从地球走向遥远的太空。天文导航通过探测天体位置确定测量载体的方位信息，具有隐蔽性好，可靠性高，不受电磁干扰，能自主工作的特点，因此得到了广泛应用。但是传统天文导航定位技术容易受天气影响，在云、雨、雾等天气下不能使用。偏振光导航定位技术在传统天文导航定位技术基础上发展而来。它不测量导航天体的直射光信号，而是测量该天体直射光被大气散射所产生的偏振图景信息，因而可以在云、雨、雾等导航天体被遮住的天气情况下使用。现有偏振光导航定位系统结构复杂，测量速度慢，测量精度低，只能满足载体的方向导航要求，不能满足载体自主定位的功能要求。本论文针对现有偏振光导航定位系统不足，对偏振光导航定位关键技术进行了深入的理论分析与实验研究，研制了基于视觉仿生原理的时分复用偏振光导航定位系统实验样机，实现了载体的自主导航定位。 |
| 英文摘要 | Perception of the position and orientation is the foundation of human activities; therefore the Navigation and Positioning Technologies(PT) are developed and become the basis for numerous human activities. Modern NPT play an important role in a variety of fields and contributes greatly to national economy as well as national defense construction. NPT expand the scope of human activities, from land to ocean, from the earth to the outer space. Celestial navigation is one of the most widely used navigation technologies. Navigator's location is measured by detecting and positioning celestial stars in celestial navigation. Celestial navigation has many kinds It's very reliable; it's anti-interference; it has traditional celestial navigation can not the ability to work of advantages. independently. But the be used in certain weather conditions, such as cloudy, rainy or foggy days simply because celestial stars are blinded. As a new type of celestial navigation, polarized skylight navigation and positioning technology, was proposed in recent years. It inherits the advantages of traditional celestial avigation technology. It can be used in certain weather conditions that the traditional celestial navigation can not be used. However, current polarized skylight navigation and positioning systems have complicated structure, slow response speed, and low navigation accuracy. In order to solve these problems, new polarized skylight navigation and positioning techniques are developed and studied both in theory and by experiments in this dissertation. A measurement system based on the techniques is developed. Its position and orientation can be obtained reliably. |
