摘　　要：在进行常规的水平角和高度角测量时,都需要将测量仪器精确整平或通过仪器的自动补偿功能对观测值进行改正。但是部分设备如普通光学经纬仪、测量相机等测量仪器不具备精确整平或自动补偿的功能,影响了水平角和高度角的观测。本文提出了一种水平角和高度角测量值的二维倾斜改正方法。利用倾角传感器检测测量仪器的二维倾角,并根据倾角值对水平角和高度角的观测值进行改正。实验表明:利用该方法只需将测量仪器概略整平,即可将水平角和高度角观测值从测量平面改正到水平面;并且能够估计其精度。While observing the horizontal angles and elevation angles,leveling the instruments are indispensable.However,many observing instruments such as optical theodolite and surveying camera are hard to be leveled.Therefore,a two-dimensional slope correction algorithm of horizontal angle and elevation angle was introduced,which could correct the observed value based on a two-dimensional gradienter.The experiments indicated that the horizontal angles and elevation angles could be corrected from observing plane to horizontal plane,with only roughly levelingthe instruments,and the standard deviation of the horizontal angles and elevation angles could also be calculated.
