| 中文摘要: |
| 针对火箭橇超长尺寸位置参数的高精度测量需求,设计了一种采用激光跟踪仪与全站仪的协同组网测量方法。 该方法
集成两种仪器各自优势满足测量需求。 同时引入坐标控制场用来构建约束场,建立约束方程。 采用加权融合的方法优化权值,
采用 Levenberg-Marquard 寻优算法求解方程组的最优解。 做了现场条件下的试验并采用与基准尺标准长度比对的方法对精度
进行了分析验证。 结果表明,在 3 km 范围内测量误差保持在 3 mm,实现了高精度、高效率的对超长距离位置信息进行测量。 |
| 英文摘要: |
| In order to meet the high-precision measurement requirements of the ultra-long position parameters of rocket skids, a
collaborative network measurement method using a laser tracker and a total station was designed, which can integrate the advantages of
the both systems. The coordinate control field is introduced to construct the constraint field and the constraint equation. The weights are
used to optimize the weights, and the Levenberg-Marquard optimization algorithm is used to solve the optimal solution of the equations.
Tests were performed under field conditions and the accuracy was analyzed and compared with the standard length of the reference ruler.
The results show that the measurement error is kept at 3 mm within the range of 3 km, which realizes high-precision and high-efficiency
measurement of ultra long distance position information. |
