例句与用法
- This system provides pulse signal and direction signal to step motor driver by computer ’ s controlling step motor control card , and makes motor and guage ’ s pointer rotate . computer gets the micro displacement measured by grating measuring system via rs232 serial port , and acquires guage ’ s image by high precison ccd camera , then processes the guage ’ s image by software , including pre - processing , graying , binarization , thinning and hough transform , so as to recognize the position of guage ’ s pointer , finally calculates all kinds of precision on basis of algorithm established by national detecting rules of gauges
本系统通过计算机控制步进电机控制卡来给出步进电机驱动器需要的脉冲信号和方向信号,进而带动电机驱动仪表指针转动,计算机通过串口实时采集光栅测量系统的微位移信号,并且通过高精度ccd摄像机实时获取表盘图像数据,同时通过计算机软件实现表盘图像处理,包括预处理、灰度化、二值化、细化和hough变换等,最终快速识别出表盘指针的位置,并根据国家表类检定规程所制定的算法检定出指针式仪表的各种精度。
