Simplified 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...
متن کاملAutomatic Camera Placement for Robot Vision Tasks
Remote sensors such as CCD cameras can be used for a variety of robot sensing tasks, but given restrictions on camera location and imaging geometry, task constraints, and visual occlusion it can be difficult to find viewing positions from which the task can be completed. The complexity of these constraints suggests that automated, quantitative methods of sensor placement are likely to be useful...
متن کاملAutomation and calibration for robot vision systems
General-purpose robot vision includes a number of different tasks that impose a great variety of imaging conditions and requirements. To support the full range of these tasks, an imaging system must provide a very wide dynamic range and high precision in both geometric and radiometric characteristics. In general, this can only be accomplished by a highly precise, automated imaging system. This ...
متن کاملSelf-Calibration of Camera-Equipped Robot Manipulators
A new approach to self-calibrate a camera-equipped robot manipulator is proposed in this paper. Self-calibration here means that the camera-robot system is capable of determining its geometric parameters without any external measurements and/or ground truth calibration data. With the proposed approach, one is able to identify all the rotational parameters and, up to a scale factor, all the tran...
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...
