摘　　要：为适应桥梁线性监测,提出了一种近景摄影测量方法。通过布设监控点,基于单反相机Canon FEOSF6D和全站仪得到监控点坐标,通过DLT算法对监控点坐标进行转换,得到桥梁的立面测绘图,为后期桥梁的线性分析奠定基础。文中以某段桥为实例,对该法的应用效果进行分析,分析结果表明:桥梁点位解算值与设计值差值全部都在1mm范围内,最大差值为0.83mm,测量数据能够较好的反应桥梁的主要信息,测量数据十分可靠。To meet the bridge linear monitoring,It present a close-range photogrammetry.Laid by the monitoring point,based on the SLR Canon FEOSF6 D monitored and total station coordinates by DLT algorithm monitoring point coordinate conversion to obtain elevation mapping diagram of the bridge,lay the foundation for post-linear analysis of the bridge.Text to a certain bridge as an example,the analysis of the effect of the application method,the results showed that： Bridge Point solver designed value all the difference in the range of 1mm,the maximum difference of 0. 83 mm,the measured data can be more good reaction main message of the bridge,very reliable measurement data.
