近景摄影测量实习报告

1、近景摄影测量实习报告2011 年 5 月 30 日1 实习任务 -32 外业控制点的观测与解算 -33 近景影像获取 -44 LPS刺点点位 -45 光束法平差与精度评定 -56 总结 -111 实习任务（1）外业控制点的观测与解算（2）近景影像获取并运用LPS软件刺点及解算所有控制点坐标。（3）用LPS软件进行光束法平差与精度评定，生成报告2外业控制点的观测与解算：根据近景摄影实习场地布设的控制点，根据“前方交会”和“间接高程”的方法，量测及计算得到22个控制点在同一坐标系下的坐标，并根据两个已知实际地面坐标的点推算出其他点的地面坐标。设置A、B两个测站，以A为原点，AB边为Y轴，铅垂线方向

2、为Z轴建立空间直角坐标系。（1）以普通测量的前方交会解算控制点的平面坐标。（2）按“间接高程”的方法再解求其高程。22个控制点地面坐标解算结果如下：点号XYH20001497.5045353.7463295.68720002497.4545353.7436299.886120003497.4345353.7873304.282120004497.7772353.8018308.446320005504.8173345.8541297.056320006504.4204345.7035304.784220007508.6227342.3816294.448320008508.7732342.38

5、将2，8，10，16，20号点设置为控制点，并使用全班成果整理后的坐标成果。最终成果点号XYZ20001497.5045353.7463295.68720002497.4532353.7473299.895320003497.4348353.7846304.303420004497.7782353.8025308.477320005504.8361345.8318297.059520006504.4386345.6825304.80520007508.6489342.3564294.444620008508.8008342.3524298.683220009508.706342.3557302
