摘要:
针对自动导引车(AGV)现有导航方式存在定位精度低、稳定性差、附加成本高等问题,建立了一种基于RFID和视觉的复合导航控制系统。该导航控制系统利用RFID技术实现一次工位识别停车;利用视觉技术建立图像巡线识别系统,实现二次精确定位停车,从而使得AGV更加精确、高效地完成复杂的导航作业任务。软件系统通过对导引图像灰度二值化分割、边缘提取、去噪处理以及直线拟合实现了对导引线、十字线以及驻车线的识别,解决了AGV转运过程中对交叉路径、驻车标志识别精度低以及噪点干扰的问题。该控制系统在实际应用中可提升AGV定位精度至5 mm,角度精度0.1度,既满足了大空间范围内的连续定位,又可以满足作业工位处高精度二次定位需求,实现AGV在工业转运过程中的自动化应用。
Abstract:
Aiming at the problems of low positioning accuracy,poor stability and high additional cost in the existing navigation methods of automatic guided vehicle (AGV),we establish a combined navigation control system based on RFID and vision. This system uses RFID technology to realize the recognition of primary station parking and the visual technology to establish the image line patrol identification system for realization of the secondary precise positioning and parking,so that the AGV can complete the complex navigation tasks more accurately and efficiently. The software system realizes the recognition of the guide line,crosshair and parking line through gray binarization segmentation,edge extraction,denoising and line fitting of the guidance image,and solves the problems of low accuracy of cross path,parking sign identification and noise interference in AGV transport. The control system can improve the AGV positioning accuracy to 5 mm and the angle accuracy to 0. 1 degree in practical application,which can not only meet the continuous positioning in a wide range of space,but also meet the requirements of high precision secondary positioning at the work station,realizing the automatic application of AGV in the process of industrial transport.
