摘　　要：空间距离标准装置是校准地面激光扫描仪的重要计量标准器,其标靶球的空间距离测量一直是其难点,目前大多是采用激光跟踪仪来测量。提出使用多台全站仪交会来进行标靶球的坐标测量,首先通过后方交会、免棱镜测量可以快速方便地得到特征点的概略坐标,然后通过互瞄建立定向基准,最后通过整体平差得到高精度的特征点坐标。实例证明,这套系统的精度优于0.1 mm,能够满足空间距离标准装置的校准精度要求。Space distance standard device is an important metrological standard for the calibrating terrestrial laser scanner.The measurement of the space distance of the target ball has always been a difficult problem.At present,most are measured by laser tracker.In this paper,we propose the coordinate measurement of target sphere by total station intersection survey.Firstly,the outline coordinates of feature points can be obtained quickly and conveniently by rear rendezvous and non-prism measurement.Then,the orientation datum can be established by mutual aiming.Finally,the high-precision coordinates of feature points can be obtained by overall adjustment.The example proves that the accuracy of this system is better than 0.1 mm,and it can meet the calibration accuracy requirement of space distance standard device.
