针对目前标准钢卷尺、工作钢卷尺、钢直尺及其它线纹尺测量过程中遇到的劳动强度大、工作效率低以及测量准确度不高等问题,基于自动对焦机器视觉技术对线纹间隔进行测量的原理,采用高精度光栅、精确的运动控制技术,研制了影像式钢卷尺\直尺全自动检测装置。测装置共用一个大理石平台和外罩,控制系统和其它机械结构系统相互独立。该装置采用高稳定性大理石平台,自动收放钢卷尺旋转结构以及精确的自动对焦机器视觉技术,从而实现了钢卷尺、钢直尺及其它线纹尺参数的全自动、高精度测量。该装置使用简便,结果直观,具有实际应用价值和市场前景。

Taking account of the problems that are labor-intensive,inefficient and poor-precision during the measurement of standard steel tape, working steel tape,straight steel ruler and other linear scales, automatic standard device of image type steel tape and ruler are developed based on automatic focusing machine vision technology, and high precision grating and motion control technology are employed. The devices consisted of automatic standard devices of image type steel tape/ruler and working steel tape, and the two devices shared one marble platform and outer cover, while the control system and other mechanical structure system are independent. Full automatization and high accurate measurement are achieved through stable of marble platform,automatic retractable steel tape rotating structure and accurate auto focus machine vision technology. Due to easy operation with intuitionistic results, the devices have a great value of usage and broader marketing perspective
