چکیده

A new method for robotics camera calibration based on a linear computation and using a coplanar group of calibration points is presented in this paper. This new method suppresses the constraint presented by the RAC calibration model of having an incidence angle between the optical axis and the calibration plane of at least 30 degrees. The parameters are obtained based on a multi-step calculation, and the accuracy of the parameters is strongly increased when used on a iterative calibration. Experimental and simulated analyses results are presented. A comparative analysis between this new method and the RAC method is presented.

Iterative Multi-Step Explicit Camera Calibration

Perspective camera calibration has been i n the last decades a research subject for a large group of researchers and as a result several camera calibration methodologies can be found i n the literature. However only a small number of those methods base their approaches o n the use of monoplane calibration points. This paper describes one of those methodologies that uses monoplane calibration po...

Determining the dominant plane from uncalibrated stereo vision by a robust and convergent iterative approach without correspondence

A robust, iterative approach is introduced for finding the dominant plane in a scene using stereo vision. Neither camera calibration nor stereo correspondence is required. Iterative two-step methods have been applied to various problems in computer vision, but only recently Cohen has formalized a framework that guarantees (at least local) convergence of such methods. In this paper we adopt this...

An Iterative Distortion Compensation Algorithm for Camera Calibration Based on Phase Target

Camera distortion is a critical factor affecting the accuracy of camera calibration. A conventional calibration approach cannot satisfy the requirement of a measurement system demanding high calibration accuracy due to the inaccurate distortion compensation. This paper presents a novel camera calibration method with an iterative distortion compensation algorithm. The initial parameters of the c...
