Video-Assisted Global Positioning in Terrain Navigation: Hough Transform Solution
نویسندگان
چکیده
We present a rigorous geometric analysis of the computation of the global position of an airborne video camera using aerial images of known landmarks. This has also been known as the perspective-n-point (PnP) problem. Based on the analysis, a robust Hough transform-like method, facilitated by a class of CORDIC-structured computations, to nd the solution for the problem, is shown feasible within the framework of terrain navigation. It empowers aerial surveillance systems to navigate e ectively when the global position and inertial navigation sensors become faulty, inaccurate, or dysfunctional.

متن کاملGlobal Hough Localization for Mobile Robots in Polygonal Environments
|Knowing the position of a mobile robot in the environment in which it operates is an important element for e ectively accomplishing complex tasks requiring autonomous navigation. Among several existing techniques for robot self-localization, a new approach called Hough Localization was proposed for map matching in the Hough domain, that turned out to be reliable and eÆcient for position tracki...
متن کاملVideo-aided GPS/INS Positioning and Attitude Determination
NAVSYS have developed a GPS/inertial/video integrated system, the GI-Eye that is designed to provide precision 3-D mapping and modeling data. For both military and commercial applications, there is a need to have a robust method of continuing operation during periods of GPS drop-outs. When the GPS satellite signals are denied, either through intentional jamming or by natural conditions such as ...
متن کاملRobust positioning of drones for land use monitoring in strong terrain relief using vision-based navigation
For land use monitoring, the main problems are robust positioning in urban canyons and strong terrain reliefs with the use of GPS system only. Indeed, satellite signal reflection and shielding in urban canyons and strong terrain relief results in problems with correct positioning. Using GNSS-RTK does not solve the problem completely because in some complex situations the whole satellite's syste...
متن کاملVision-based System for Self-positioning and Calibration
This work presents a solution for self-positioning (i.e. heading angle and offset) a vision system with respect to a line and the calibration of the single vision system. The tools Hough transform and camera model are used to obtain the position of the camera. The calibration procedure proposed calculates several parameters, which are used in the positioned process of the vision system. Experim...
