| 摘 要： | 在微震颤状态下，TCA2003智能全站仪的垂直自动补偿器不能正常工作，因此由持续监测过程中的温度变化而引起的仪器竖轴周期性倾斜摆动不能通过自动补偿来改正。本文提出了一种新的非线性坐标转换方法，该方法用于TCA2003变形监测数据处理可以消除竖轴倾斜的影响，提取高精度的变形量，而且适用于大角度的三维坐标转换并且不依赖于初值。 |

| Abstract: | When the vertical automatic compensators of TCA2003 Measurement robot can not work in slight dindle statue,inclined oscillation of vertical axis caused by temperature variation can't be corrected by automatic com-pensators. A new non-linear coordinate tranfomation method is presented here. Application of this method to de-formation observation of TCA 2003 can eliminate system error caused by inclined oscillation of vertical axis and get high precise deformation values. It's suitable for three-dimension of coordinate transformation of large angle rotation,and relies less on the initial values of seven transformation parameters. |
