摘要

W artykule zaprezentowano unikalną metodologię i wyniki wyznaczenia współczynnika rozszerzalności termicznej oraz kalibracji pary wzorców liniowych do sytemu fotogrametrycznego DPA Pro firmy AICON 3D Systems GmbH o długości 1,34 m. Stosowne badania przeprowadzono w Geodezyjnym Laboratorium Metrologicznym Wydziału Geodezji Górniczej i Inżynierii Środowiska AGH w Krakowie na zlecenie firmy MAN Bus Sp. z o.o.. Oddział w Starachowicach.%The paper presents a unique methodology and results of determining the coefficient of thermal expansion and calibration of a pair of measurement standards of a DPA Pro photogrammetric system (Fig. 1) produced by AICON 3D Systems. The tests were carried out in the Geodetic Metrology Laboratory at Department of Mining Surveying and Environmental Engineering, AGH University of Science and Technology in Krakow, on behalf of MAN Bus, Branch Starachowice. Determination of the coefficient of thermal expansion was performed in a specially adapted thermal chamber (Fig. 2). The temperatures obtained in the thermal chamber during measurements of changes of the length caused by thermal factor ranged from 7 °C to 37 °C, at the average temperature of 22 ℃ (Fig. 3). The resulting thermal expansion coefficient was 0.31 μm/m/℃ with the measurement uncertainty at 95% confidence level (2 sigma) of + 0.06 μm/m/℃. Calibration of a pair measurement standards was made in a vertical (Fig. 5) and horizontal (Fig. 6) position twice, independently. As a master of lenght there was used the Hewlett-Packard HP 5529 laser interferometer. A two-axis measurement system of a vertical comparator allowed simultaneous measurement of microscope inclination (Fig. 4). Length of the measurement standards in the horizontal and vertical positions differs by about 8 μm, because the pattern in the horizontal position is shorter due to sagging under its own weight (Table 1). The measurement uncertainty of the DPA Pro standard length at the 95% confidence level was ± 3.9 μm.

Starachowice。%中的分支本文提供了一种独特的方法和方法,用于确定AICON 3D Systems生产的DPA Pro摄影测量系统(图1)的一对测量标准的热膨胀系数和校准标准。测试是在克拉科夫AGH科技大学采矿测量与环境工程系的大地测量实验室中,代表MAN Bus,Starachowice分公司进行的。热膨胀系数的确定是在专门改装的热室中进行的(图2)。在测量由热因子引起的长度变化期间,在热室中获得的温度范围为7℃至37℃,平均温度为22℃(图3)。所得的热膨胀系数为0.31μm/ m /℃,在95%置信度(2 sigma)下的测量不确定度为+0.06μm/ m /℃。分别在垂直位置(图5)和水平位置(图6)两次校准一对测量标准。作为长度的主要部分,使用了惠普HP 5529激光干涉仪。垂直比较器的两轴测量系统允许同时测量显微镜的倾斜度(图4)。水平和垂直位置的测量标准长度相差约8μm,因为水平位置的图案由于自重下垂而变短(表1)。 DPA Pro标准长度在95%置信水平下的测量不确定度为±3.9μm。
