摘要
为了校准条码水准标尺,建立了校准装置.校准装置系统由固定桥式三坐标测量机、平面反射镜和数字水准仪构成,经置中调整后,形成精密测量系统,通过平面反射镜将水平放置条码水准标尺转置为垂直立像,并经数字水准仪读取和解码,得到条码尺示值,与标准位移值形成数据列,经分段叠加最小二乘拟合,以直线斜率作为被测条码尺的每米真长补偿因子.校准装置实现方式简便,占地空间小,测量精度高,数据评价科学.
Abstract
A special-purpose calibration system has been developed to calibrate the barcode leveling rod.This system consists of a fixed-bridge coordinate measuring machine(CMM),a plane mirror,and a digital level.A highly precise measurement system is formed after meticulous central alignment adjust-ments.Within this system,the horizontally positioned barcode leveling rod is optically transformed into a vertical image via the plane mirror,which is then captured and decoded by the digital level to derive the displayed value of the barcode rod.These values are compiled alongside corresponding standard displace-ment values into a dataset.Fitting by the piecewise linear least squares,the linear slope is extracted and utilized as the compensation factor for the true length per meter of the calibrated barcode rod.This system boasts a simple implementation process,minimal floor space,high precision,and a scientifically rigorous approach to data assessment.
