摘要
机房智能巡检机器人须对仪器仪表进行精准高效的识别,基于数字图像处理的指针式仪表自动读数算法,大部分是在标准环境下进行的,即保证摄像机与指针式仪表表盘水平放置,无视角偏差,无旋转偏差,此种方式不能很好地解决垂直刻度指针仪表的读数问题。文章提出一种基于单目视觉的三角测量法,可高度定位,从而精准地捕捉仪器仪表读数,测量精度达到毫米级别,具有广泛应用性。
Intelligent inspection robot in computer room needs to identify the instruments accurately and efficiently.Most of the automatic reading algorithms of pointer instruments based on digital image processing are carried out in standard environment,that is,to ensure that the camera and the dial of pointer instruments are placed horizontally,without visual angle deviation and rotation deviation.This method can't solve the reading problem of vertical scale pointer instruments well.In this paper,a triangulation method based on monocular vision is proposed,which can be highly positioned to accurately capture the readings of instruments and meters,and its measurement accuracy reaches millimeter level,so it has wide application.
