Sampling on Concentric Circles
Two forms of a sampling theorem for concentric circles are established for a bandlimited two-dimensional (2-D) function. The location of the samples is prescribed either on equidistant circles or on the roots of the Bessel function J0( ). Both methods give comparable results, however, the number of samples required for their numerical evaluation is significantly less for the root-sampling formu...
متن کاملCamera Calibration Using Two Concentric Circles
We present a simple calibration method for computing the extrinsic parameters (pose) and intrinsic parameters (focal length and principal point) of a camera by imaging a pattern of known geometry. Usually, the patterns used in calibration algorithms are complex to build (three orthogonal planes) or need a lot of features (checkerboard-like pattern). We propose using just two concentric circles ...
متن کاملDrawing Metro Maps on Concentric Circles
This thesis examines algorithms for the drawing of metro maps. The most important elements of a metro map are stations and lines connecting the stations. In the context of this thesis, we restrict the elements used for representing lines to one of two classes: On the one hand, circular segments lying on circles with a common center S are allowed. On the other hand, line segments lying on lines ...
متن کاملA Camera Calibration Method using Concentric Circles for Vision Applications
In this paper, we present a new method for camera calibration using concentric circles. We demonstrate that camera calibration is possible using two views of a concentric circle with known size. A new method to determine the position of the projected center of the circle is introduced. Based on the accurate estimation of the projected circle center of two sets of 3-D concentric circles, the pro...
متن کاملAn Algorithm for the Detection of Multiple Concentric Circles
This paper presents a method for the detection of multiple concentric circles which is based on the Hough Transform (HT). In order to reduce time and memory space the concentric circle detection with the HT is separated in two stages, one for the center detection and another for the radius determination. A new HT algorithm is proposed for the center detection stage which is simple, fast and rob...
