Calibration Method Using Concentric Circles Planar Template and its Application

Abstract:

This article introduces a new calibration method for machine vision measurement system--calibration method using concentric circles planar template. This method not only considering lens distortion and random errors introduced by the process of calibration, but also overcome limitation of strict demands for the standard parts’ position and complexity in stereovision computation, it also capable of conduct calibration to the whole scene depth space, effectively improve the efficiency of calibration with its simple and high precision mean. A relatively high precision can be achieved by applying this new method to diameter measurement of cable line, which is suitable to conduct on-field industrial dimension measurement calibration.
