中文摘要：

为了研究反射片量测模式应用于相似材料模拟实验中的监测精度,根据相似材料模型的实际观测和误差传播定律计算了点位坐标的理论量测精度。设计了现场实验,采用布尔莎七参数模型,基于Matlab计算平台把物方坐标系空间坐标自动转化为局部坐标系坐标,并与近景摄影测量的量测结果进行了对比和分析。结果表明,全站仪反射片量测模式点位坐标理论中误差沿X方向的极值为±1.5 mm,沿Y向和Z向的极值为±1.06 mm。当竖直观测角和水平观测角控制在[-π/4,π/4]以内时,点位坐标中误差可以控制在亚毫米级。与数字近景摄影测量点位坐标量测结果对比,全站仪反射片坐标测量模式沿X向的实际点位量测中误差为0.43 mm,Y向的点位量测中误差为0.37 mm。

英文摘要：

In order to research surveying precision of similar material simulation experiment measured by reflector plate pattern,according to measurement practice of similar material model error propagation law,theoretical magnitudes of point site coordinates precision were calculated. According to field test,based on Bursa theoretical model,point coordinates within surveying coordinate system were transferred automatically to local coordinate system utilizing the software Matlab. The transferred coordinates were analyzed and contrasted with the results obtained by digital close-range photogrammetry. The studies show that theoretical mean error extreme value of points coordinate is ± 1. 5mm along X coordinate axial direction based on total station instrument reflector plate pattern,and ± 1. 06 mm along X and Y coordinate axial direction respectively. When vertical angle and horizontal angle are controlled from-π /4 to π /4,mean error of point site coordinates can be controlled within sub millimeter. Comparing with digital close-range photogrammetry results,actual mean error of point site measurement is 0. 43 mm and 0. 37 mm along X and Y coordinate axial direction respectively through the pattern of total station instrument reflector plate.
