摘要：As accurate and widely available as GNSS service is, it still cannot be fully accessed everywhere, at all times, and under all conditions. In recent years, the search for seamless uninterrupted positioning, navigation, and timing has investigated a variety of other technologies that could be combined with GNSS to provide a more robust utility. This article looks into the feasibility of exploiting vision-based measurements for navigation and presents a method for using a limited number of GPS carrier phase measurements with features that are extracted from images of a monocular video camera.
