借助高精度的经纬仪测量系统,对MetroIn_DPM工业摄影测量系统进行了精度评定,结果表明,该系统在实验室和测量现场均能达到亚毫米级精度,且外业测量方便快捷,可以满足加油站罩棚的测量需求。用MetroIn_DPM系统对罩棚进行了三期变形监测,以经纬仪系统的测量数据作为外部检核条件分析了罩棚变形,加固了加油站地基和支柱,有效提高了其抵抗变形的能力。
The accuracy of the MetroIn_DPM industrial photogrammetry system was evaluated with the help of a high-precision theodolite measuring system. The results show that the system can achieve sub-millimeter accuracy in the laboratory and measurement sites, and the field measurement is quick and convenient, The measurement needs. The MetroIn_DPM system was used to carry out the third phase deformation monitoring of the canopy. The deformation of the canopy was analyzed with the survey data of the theodolite system as an external inspection condition, and the foundation and pillars of the gas station were reinforced, which effectively enhanced their resistance to deformation.
