加油站罩棚变形监测的摄影测量方法与精度分析

Photogrammetric Deformation Monitoring Method and Accuracy Analysis of Gas Station's Tent

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。

With the help of high-precision theodolite measuring system,the MetroIn_DPM industrial photogrammetry system accuracy assessment was carried out.The results show that the system can achieve the sub millimeter level accuracy in the laboratory and field measurement,and has convenient and rapid measurement which,can satisfy the measurement requirements of gas station＇s tent.Three phases of deformation monitoring work were completed by the MetroIn_DPM system,and the tent＇s deformation was analyzed with the theodolite measurements as external check conditions.Gas station＇s foundation and pillars were strengthened,which can improve its ability to resist deformation.
