摘要
针对TCA2003测量机器人机载联测距离程序"Tie Distance",推导了数据采集过程中任意两点不通视时通过变换测站点的位置间接测量两点间的距离和高差的精度计算公式,利用实验数据计算分析不同设站位置对联测距离精度的影响,得出实际工程应用中当待测两点间的距离、TCA2003的测角及测距精度确定后,测站点位置位于两待测点的垂直平分线上且靠近于两点的连线时,联测距离精度较高可代替直接测距。
Based on the airborne connection survey distance measurement program"Tie Distance"of TCA2003 measurement robot,the precision calculation formula is derived for measuring the distance and elevation difference between two points indirectly by changing the position of the measurement site when any two points don’t have intervisibility during the data acquisition process,the impact of different station locations on the connection survey distance accuracy are calculated and analyzed using experimental data,the conclusion that connection survey distance accuracy is higher which can replace the direct ranging is obtained when the distance D between two points to be measured、the measurement angle and ranging accuracy of TCA2003 are determined in practical engineering applications,and also the location of the test site is located on the vertical bisector of the two test points、closed to the connection of two points.
