In this paper, we propose a new method to automatically extract the main structure (fuselage and wings) of straight wing aircraft in photographic images using line clustering. We exploit the location, length and orientation features (parallel constraint) of line segments to group them into line clusters. The different line clusters correspond to the different structure of straight wing aircraft, and...
An accurate closed form solution is proposed to estimate camera pose by several mirrored reference object images acquired via a planar mirror under different unknown poses. Compared with state-of-the-art methods, our method is more accurate when there are more than three images and has explicit geometric meanings. This method also properly handles cases in which some of the mirror poses are parallel...
The Orthogonal Iteration (OI) algorithm for pose estimation from point correspondences is global convergent, efficient and robust, which make this algorithm quite attractive. In this paper, we extend the OI algorithm to 2D-3D line correspondences and present an iterative algorithm referred to as LBOI (Line-Based Orthogonal Iterative Algorithm). We first derive a new form of fundamental equations and...
