Simplified theodolite calibration for robot metrology
Theodolites represent a well-established 3D-point-measuring technology. However when used for robot applications they have to be properly calibrated to fulfil the necessary accuracy requirements. The theodolite calibration methods, which have been reported in the literature, involve the use of costly sophisticated equipment not easily available to most users. Therefore, a new simplified calibra...
متن کاملRobust Active Stereo Calibration
We present a calibration procedure to determine the kinematic parameters of an active stereo system in a robot-centric frame of reference. Our goal was to obtain a solution of sufficient accuracy that the kinematic model information can be used to estimate scene structure given the measured motion/position of the eye and target object’s image location. We formulate our problem using canonical c...
متن کاملAccurate Camera Calibration with simplified Patterns with a Self-calibration Approach
In this paper we present a unified approach for calibration and self-calibration of multi-camera systems. The technique is based on an algorithm for the resolution of the self-calibration problem, with which it is possible to find the camera geometry up to an arbitrary perspective transformation of the calibrated scene space. The correct geometry is then obtained by properly exploiting the dime...
متن کاملA Family of Simplified Geometric Distortion Models for Camera Calibration
The commonly used radial distortion model for camera calibration is in fact an assumption or a restriction. In practice, camera distortion could happen in a general geometrical manner that is not limited to the radial sense. This paper proposes a simplified geometrical distortion modeling method by using two different radial distortion functions in the two image axes. A family of simplified geo...
متن کاملSimplified intrinsic camera calibration and hand-eye calibration for robot vision
In this paper we investigate how intrinsic camera calibration and hand-eye calibration can be performed on a robot vision system using the simplest possible motions and a planar calibration object. The standard methods on plane-based camera calibration are extended with theory on how to use pure translational motions for the intrinsic calibration and we see how hand-eye calibration can be perfo...
