Leica Infinity: How to perform a network adjustment

使用Leica Infinity，您可以使用GNSS，TPS和水平观测值或它们的任何组合来调整测量网络。预先分析和循环计算用于对观测值的初始检查。内部受限调整提供了有关观测质量的有用信息，而控制点可以用于限制调整。所有这些都可以帮助您提高工作的精度和信心，而这必须是正确的！

执行网络调整很简单。这是关于如何进行无穷大的网络调整的快速工作流程。

导入，可视化和准备调整数据

To import the data and the coordinate system used in adjustment, select Import from the ribbon bar. In the Import dialog, choose the correct files and select Import.

• 使用Shift-Rotate尺度移动TPS数据以适合GNSS数据和控制点。
• Run all possible Sets of Angles to create the reduced TPS observations that will be used in adjustment.
• Zoom, rotate and pan in the graphical view to get an overview of the combined network.

进行调整之前检查数据质量

To run a pre-analysis, select Run Pre-Analysis - 3D from the Adjustment ribbon bar. You can create a comprehensive report for the results that provides you with an overview of missing or problematic data. Pre-Analysis can identify possible weaknesses in a network, detect unknowns that cannot be solved and check input data. Run Compute Loops – 3D from the Adjustment ribbon bar to check any out-of-tolerance loop misclosures before running an adjustment.

Run inner-constrained adjustment

检查数据后，通过单击“调整功能区”栏的完整3D调整来运行内部约束调整。创建一个调整报告，以检查观测值之间可能的离群值。删除异常值并重新运行内部约束调整，直到所有观察结果都在准确性和可靠性的定义公差范围内。

Fix control points and run constrained adjustment

When the outliers have been removed, navigate to the Define Coordinate Constraints side tab of the Adjustments tab in the Inspector and fix the control points in 2D and 1D. Run Full 3D Adjustment from the Adjustment ribbon bar. Create an adjustment report to check for possible outliers among the control points. Remove the outliers and re-run a constrained adjustment until all control points are within the defined tolerances of accuracy and reliability.
