Improving camera calibration Applying a least squares method to control point measurement
نویسنده
چکیده
A nonlinear optimization based method for measuring circular control points for use with camera calibration is presented. The displacement of circle centers, caused by projection, is addressed and corrected. Camera calibration is performed taking both radial and tangential lens distortion into account. The results show some improvement with the least squares method over the classical centroid method. The results with and without circle center displacement correction were similar. However, the technique was useful for outlier detection.

Dynamic camera self-calibration from controlled motion sequences
In order to recover camera motion and 3-d structure from a sequence of images we must rst relate points in the image plane to directions in space. This paper describes a least-squares algorithm for computing camera calibration from a series of motion sequences for which the translational direction of the camera is known. The method does not require special calibration objects or scene structure...
متن کاملSimultaneous Spectrophotometric Determination of Iron, Cobalt and Copper by Partial Least-Squares Calibration Method in Micellar Medium
Iron, cobalt and copper are metals, which appear together in many real samples, both natural and artificial. Recently a classical univariate micellar colorimetric method has been developed for determination of these metal ions. The organized molecular assemblies such as micelles are used in spectroscopic measurements due to their possible effects on the systems of interest. The ability of mi...

متن کاملCalibration Method for an Augmented Reality System
In geometrical camera calibration, the objective is to determine a set of camera parameters that describe the mapping between 3D references coordinates and 2D image coordinates. In this paper, a technique of calibration and tracking based on both a least squares method is presented and a correlation technique developed as part of an augmented reality system. This approach is fast and it can be ...
متن کاملImage-based Modeling Using a Two-step Camera Calibration Method
We present a two-step camera calibration process based on linear least squares formulations. We show how to apply this process to build an integrated modeling environment, in which a scene is modeled by having the user specify, on a given image, a set of reference points (used for camera calibration) and object points (used for positioning the objects in the scene). Once this has been done, syn...
