Getting started with metigo 3D
These guidelines gives you a short and comprehensive introduction to the standard metigo® 3D approach, which starts with capturing and treating images, continues with generating point clouds and ends with the creation of true-to-scale orthophotos. Links direct you to dedicated articles with further information about the specific subject.
Create a project
Using the menu Project > New Project > New or the button on the symbol bar a new project is created.
For further information see Project Management (metigo 3D)
Create a camera
Following you create a camera for your new project respectively load a prevoiously created one. To create a camera right-click on the node cameras of the tree orientations at the project tree on the left side of the GUI. Select Create Camera from the context menu.
For detailed information see Camera.
To load images rightt-click on the node source images of the tree Orientations on the left and select Load Source Images.
For further information see Source Images (metigo 3D)
To create image groups open the context menu of the node source images of the tree Orientations on the left and select Generate Image Groups.... Generating these image groups, models will be created automatically.
Name the image group in the prompted dialogue and confirm with OK. If the automatic creation does not start you can create the stereo models manually. For further information compare Stereo Project.
Analysing the model
Right-click on the created image group at the orientation tree and press Model Analysis.
The prompted dialogue suggests a sequence of models so that the absolute orientation only has to be calculated manually for the first stereo model (compare Absolute Orientation). The calculated orientation will then be transferred automatically to the other models. However the overlap of the models to each other has to be sufficient. For the first model you still have to measure GCPs in both images and recalculate the relative orientation for the selected model where required.
After you have chosen the start model right click on the respective image group in the Orientation tree and select Orientate all models relatively. The settings (base and filtering) will be applied from the tool window on the right. You also can orientate every model individually.
See Relative Orientation for more details.
After the relative orientation has been conducted successfully press the button ##.
Calculate the absolute orientation of the selected with the given GCPs. If this are not yet existing load 3D-GCPs into the project (compare GCP).
--> After you have calculated the orientation for the first model, you can assign this to the other models of this group automatically (assumed that sufficient overlap of the models exists). Therefore call the context menu and click on Orientate all Models automatically.
See Absolute Orientation for more details.
Save orientated models
After you have orientated your models successfully save them by clicking at the right part of your window on Save Model. You can also save all models at once by selecting save all orientated models in the context menu.
Please, read Point Cloud Generation for further information.
Start the Point Cloud Generation
Define an increment in the right part of your window. By inserting the seed cluster to a batch list you can create for all selected seed clusters a point cloud with an identical point distance. You also can process the batch list via the context menu in the tree. Right-click on the seed cluster and select batch list (seed cluster). Of course you als can generate a point cloud for every individual seed cluster.
Further information Point Cloud Generation.
Click the button Colour Selection at the section Selection on the right part of the window. Select the required colour and edit it.
See for further information Purging Point Clouds by Colour Selection.
Merging Point Clouds
Merge several point clouds to a total point cloud. You merge point clouds in an optimal way using the marginal correction transformation (ICP). Thereto click on the button File:3Dicon and select the seed clusters.
Select the triangulation window via the button File:3Dicon. Just click the button Start at the right part of the window.
See for further information [[Creating a DSM based on Point Clouds}}.
First, click the button File:3Dicon and select your settings for texturing of digital surface models.
Instead of texturing the triangulated surface model, you also can texturing only the points, see Texturing of point clouds.
For further information, see Texturing of DSMs.
Create a UCS
For further information, see UCS Management.
To create an orthophoto, click on the button File:3Dicon and conduct the required settings at the tool window on the right.
For further information, see Generating Orthophots.
