摘要
水准仪视准线误差(i角)用于修正水准仪测量视高,因此,i角精度,特别是其校正精度,对数字水准仪的测量精度十分重要。本文介绍了天宝DiNi03型数字水准仪圆水准器校正方法,以及光学和电子i角检校的步骤和方法,为测量人员掌握基本的校正方法,为检定机构和测绘仪器维修从业人员掌握i角的检校提供了有益参考。
The level sight line error(i angle) is used to correct the height of point of sight of the level. Therefore, the accuracy of i angle, especially the correction accuracy, is very important to the measurement accuracy of the digital level. This paper puts forward the calibration and correction method of the circular level of Trimble DiNi03 digital level, the procedures and methods for optical and electronic i angle calibration and correction. It provides a useful reference for surveyors to understand the basic calibration methods, as well as for calibration institutions and surveying and mapping instrument maintenance practitioners to know the calibration and correction of i angle.
