How to work with Leica GS18 I data
Leica GS18 I GNSS RTK Rover基于GNSS，IMU和A相机的集成，利用了高度创新的视觉定位技术。通过视觉定位，用户可以从图像的距离和测量点捕获感兴趣的区域。它使您能够从现场或办公室中具有测量级准确性的图像测量点。
GS18 i的办公室工作流程基于无限。用户可以测量单点或从数据创建点云。这是一个快速的工作流程。
导入和可视化项目中的GS18 I数据
To import the GS18 I data, simply select the Import from the ribbon. In the Import dialog, highlight the DBX file and select Import. Zoom, rotate and pan in the graphical view to get an overview of the imported data and images. The imported Image Groups and associated images are listed in the Library object’s list in the Navigator.

图像的测量点
To measure points, highlight the Image Group in the Navigator and from the context menu select Open Viewer. In the Image Viewer, navigate to the desired image and measure new points. Zoom and pan to the required positions or use the magnifier for a closer look. A single click chooses the point and the same feature is automatically identified from the other images. Created points are listed in the Points View pane and can be viewed in the images.
合并图像组
The Merge Image functionality is useful to combine two or more Image Groups. It allows creating a single point cloud from multiple image groups. In the Imaging tab of the ribbon, use New to create a new Image Group. A new group will be added in the object Library in the Navigator. In the Navigator or Inspector, highlight the required Image Groups and right-click to open the context menu. Select Merge to Image group and select created Image Group. All images from the previously selected Image Groups now belong to the merged Image Group.
创建一个密集的点云
创建一个密集的点云数据捕获with GS18 I follows the same steps as creating a point cloud from UAV data. Before creating the Dense Point Cloud, define the Settings from the Imaging tab in the ribbon. Specify the Filtering threshold and the Min. Number of Matches per Point to better handle outliers or poor-quality data . The Dense point Cloud can be created by selecting the image group and choosing Dense Point Cloud from the ribbon or the context menu. The processing task starts and can be viewed in the Imaging Results section of the Inspector Imaging tab. Once the task is completed, it is moved to results section. Store the results to visualise the Dense Point Cloud in the View pane and Navigator.
