摘要: 为解决传统标定法难以处理比较灵活的标定环境,要求较低的标定精度但实时性要求较高的情况,以传统的二维平面标定法为基础,提出一种以小型地面无人机动平台的行驶环境为标定环境的改进的二维圆标定法。在Matlab/Simulink环境下实现,将传统的标定特征点由检测方块的角点改为特征圆的圆心,从而将计算量缩小为以方格角点为标定特征点的1/4,缩短了特征点的提取时间,提高了标定系统的实时性。实验结果表明,这种方法简便、高效、实用、灵活,应用环境可为任意背景。

Abstract: In order to handle relatively flexible calibration background, and meet relatively low calibration precision requirement but relatively high real-time requirement in traditional 2D plane drone calibration method, an improved calibration method on the basis of the traditional 2D calibration was put forward, which took small unmanned ground weapon mobile platforms' driving environment as calibration environment. Being realized in Matlab/Simulink environment, this method changed the traditional calibration's detecting diamonds' horn points into circle's center, at the same time reduced account quantity to quarter of diamond's horn point method, shortened the time of distilling character points and enhanced the real-time of the system. The experimental results demonstrate that this method is simple, effective, practical and flexible, and its application environment can be any background.
