This research was motivated by a need for accurate UAV navigation using camera(s) to augment inertial navigation unit data while flying over, or through an urban environment. The process of position determination using cameras follows a sequence of well defined steps. First features must be found in consecutive-in-time images and then matched across time. The underlying camera motion, as defined by...
A precise navigation method for high altitude unmanned aerial vehicle was researched. Strapdown inertial navigation system (SINS), star sensor and Bei Dou receiver were adopted in this method. Errors of SINS and misalignments of star sensor were chosen as system states of integrated navigation. A specified attitude matrix was constructed by outputs of SINS, then measurements of integrated navigation...
To represent 3-D space in detail, it is necessary to acquire 3-D shapes and textures simultaneously and efficiently through the use of precise trajectories of sensors. However, there is no reliable, quick, cheap, and handy method for acquiring accurate high-resolution 3-D data on objects in outdoor and moving environments. In this paper, we propose a combination of charge-coupled device cameras, a...
