Vision-based Positioning with a Single Camera and 3D Maps: Accuracy and Reliability Analysis
نویسندگان
چکیده
In an effort to supplement the available satelite-based positioning technology and extend such high level positioning capability to GPS-denied environments, a method of vision-based positioning with the use of single camera and newly defined 3D maps is proposed. Besides, only natural landmarks are required in the proposed method. Absolute position and orientation information can be provided in six degree of freedom. Our work here is to address the accuracy and reliability concerns of such a vision-based navigation system. The main contribution will be the newly defined 3D map and the adoption of photogrammetric 6DOF pose estimation method to improve positioning accuracy. Dilution of Precisions (DOPs) are introduced to evaluate positioning precision within the vision-based positioning domain. Quality control strategies are also applied to detect outliers in the observation and strengthen system reliability

Camera Arrangement in Visual 3D Systems using Iso-disparity Model to Enhance Depth Estimation Accuracy
In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity surfaces provides an efficient way to estimate the depth estimation uncertainty which ...

The Unmanned Aerial Vehicles (UAV) positioning in the outdoor environment is usually done by the Global Positioning System (GPS). Due to the low power of the GPS signal at the earth surface, its performance disrupted in the contaminated environments with the jamming attacks. The UAV positioning and its accuracy using GPS will be degraded in the jamming attacks. A positioning error about tens of...

Nowadays, the subject of vision metrology network design is local enhancement of the existing network. In the other words, it has changed from first to third order design concept. To improve the network, locally, some new camera stations should be added to the network in drawback areas. The accuracy of weak points is enhanced by the new images, if the related vision constraints are satisfied si...
