摘要
随着GNSS及计算机技术的不断发展,人们对室内外位置服务的需求不断增加。学校、医院、展厅、写字楼等都需要使用准确的室内外定位信息,特别是在应对紧急情况时,室内定位信息显得尤为重要。本文分析了多传感器融合的室内外定位技术研究进展,提出了基于数据融合的多传感器融合定位平台,以GPS技术为主导,结合WIFI、航位推算等定位技术的方法,通过一定的数据融合算法,增强室内外定位的完备性,为进一步实现室内外无缝定位、智慧地球等提供了参考。
With the continuous development of GNSS and computer technology, people demand for indoor and outdoor location service continues to add. Schools, hospitals, exhibition halls, office buildings and so on all need to use accurate indoor and outdoor positioning information, and especially when dealing with the emergen-cies, indoor location information is particularly important. This paper analyzes the research progress of indoor and outdoor positioning technology. The paper proposes a multi-sensor fusion positioning platform based on data fu-sion, which is dominated by GPS technology, by combining with WIFI, navigation positioning technology such as calculation method, through certain data fusion algorithm, to enhance the completeness. The paper provides a ref-erence for further realizing the seamless positioning, and smart earth.
