Three-dimensional location estimation of circular features for machine vision

Abstract: Estimation of 3-D information from 2-D image coordinates is a fundamental problem both in machine vision and computer vision. Circular features are the most common quadratic-curved features that have been addressed for 3-D location estimation. In this paper, a closed-form analytical solution to the problem of 3-D location estimation of circular features is presented. Two different cases are considered: 1) 3-D orientation and 3-D position estimation of a circular feature when its radius is known, and 2) 3-D ori… Show more

“…The concept of finding circular objects and curves in images has been studied for many years. In general, there are two different types of algorithms for curve detection (typically circles and ellipses) in images, those that are based on the Hough transform [3,15,16], and those that aren't [2,10,11,12,13]. It should be noted that this is not an exhaustive list of circle detection methods, since the main focus of this paper is not the circle detection technique.…”

“…The most common geometric features used in pose computation which are suitable for AR applications include indoor fiducial/marker based [3,19,25,32,33] and outdoor fiducial/marker based [26], the latter shows how the size of the marker contributes to robustness and ease of use. In the related computer vision literature geometric primitives considered for the estimation are often points [13,7], segments [9], lines [20], contours or points on the contours [21,24,10], conics [28,6], cylindrical objects [8] or a combination of these different features [25]. Another important issue is the registration problem.…”
