[[111:photogrammetry:strabo:project:create:projectwizard|{{ :orbitgis:return_overview.png|Return to Overview - Project Wizard}}]] ====== Project Wizard - Step 5: Model Editor ======
{{111:photogrammetry:strabo:project:create:projectwizard:project_step5.png?nolink&400|}} This wizard step is used to generate in a manual/automatic way the strips, stereomodels and strip overlap models. For a manual interpretation, you can select: * [[111:photogrammetry:strabo:project:create:projectwizard:modeleditor#Edit Strips|]] * [[111:photogrammetry:strabo:project:create:projectwizard:modeleditor#Edit Stereo Models|]] * [[111:photogrammetry:strabo:project:create:projectwizard:modeleditor#Edit Strip Overlaps|]] {{ overlap.png?nolink&170|}} To do it in an automated way, click 'generate automaticly'. In this case you can 'extend the strip overlap models' meaning that not only strip overlap between two images next to each will be created (1-2) but also the images above/below the image (1-3 and 1-4). Optimizing strips means that two images with a photo base which is lower than 50% of the mean photobase will be deleted.
\\ ----- \\ \\ ======= Edit Strips ======= The first step concerns defining the strips, press **'Edit Strips'** to get the next dialog :\\ \\ {{edit_models_edit_strips.gif?nolink|}}\\ \\ This dialog shows: * at the left side: the available images * in the middle: the strips * at the right side: the images that belong to a selected strip.\\ When starting a project, this strip list is automatically filled using the available EO parameters. If these EO parameters (Projection Center coördinates and Oriëntation Parameters) are approximate, it is possible that the strips are not 100% correctly defined. Therefore different other functions are available to correct the strip defintion if necessary.\\
**//Add new strip//** \\ \\ Pressing this button adds a strip in the 'Strips' column and emties the 'Photos in strips' column. \\ \\ \\ **//Remove selected strips//** * select the strips that you want to remove in the 'Strips' column * press the 'Remove selected strips' button. If at least one photo is not associated to a strip, a strip called 'Unassociated' will appear in the 'Strips' column, containing these non-associated photos. Removing strips will never remove images from the project \\ **//Add selected photos//** * Select one strip to which you want to add photos in the 'Strips' column * Select the photos in the 'Photos' column that you want to add to this strip * Press the button 'Add selected photos'.\\ The photos will appear in the column 'Photos in strip'. \\ \\ **//Remove selected photos//** If there photos are mistakenly assiged to a strip, they can be deleted from this strip.\\ * Select the strip containing the mistakenly assigned photos in the column 'Strips' * Select the mistakenly assigned photos in the column 'Photos in strip' * Press the button 'Remove selected photos' to remove the photos from the selected strip. \\ \\ //**Show unassociated photos**// When photos are not yet associated to a strip, and you can automatically select these photos in the 'Photos' column by pressing this button.\\ This is the easy way to add the unassociated photos to a selected strip. \\ \\ \\ //**Auto-generate strips**// This button is used when you want to regenerate the strips.\\ It will clear all the existing strips and calculates a new stip set.
\\ ====== Edit Stereo Models ====== Now the strips are defined, we can create the Stereo Models.\\ Open the next dialog by pressing on the button **'Create Models'**:\\ \\ {{edit_models_create_models.gif?nolink|}} \\ \\ This dialog shows * at the left side: the list of availbable photos. * at the right side: the Stereo Model - couples. During the creation of the Strabo project, also the Stereo Models are derived automatically.\\ The resulting list of models will only be correct if the EO's (External Oriëntations) of the imagery are correct. Sometimes, e.g. in case of approximate values, the automatic model creation can be incorrect. To correct the Stereo Model couples you can use the following functions:
**//Create model//** When you select two Photos in the 'Photos' list, then this button will become sensitive and can be pressed.\\ By pressing this button, the couple will appear in the right hand side column 'Models". \\ \\ //**Delete model**// When a model is not correct: * select the model in the 'Models' column * press the button 'Delete model' You can also select one or more models (using ctrl-c), or all the models (using ctrl-a), and then delete the selection. \\ \\ **//Reverse photos//** Reversing the model means that the Left and Right image of a stereo model are switched. If a model has to be reversed: * select the model in the 'Models' column * press the button 'Reverse model' \\ **//Auto Create strip based models//** If you want to re-create the list of models at any time, press this button.\\ The previous list will be replaced by a new one.
\\ ====== Edit Strip Overlaps ====== Strip overlap definitions are needed when you want to do Automatic Tiepoint creation. These strip overlap definitions help the software to know where to look for strip overlap. This is how the dialog looks like:\\ \\ {{stripoverlap.png?nolink&750|}} \\ \\ The dialog is devided in two parts: * the left side: defining which strips have overlap * the right side: defining a selected stripoverlap in more detail.
//**Strip Overlap Definition**// The left side of this dialog helps you to define the Strip overlap. \\ \\ //**Add overlap**// When you want to add a strip overlap that is missing or that was deleted: * Select two strips that have strip overlap. * Press the button 'Add overlap' to add the strip overlap combination to the column 'Strips with overlap'. \\ //**Remove overlap**// * Select a strip overlap that is not a 'real' strip overlap. * Remove it from the list pressing on the button 'Remove overlap'. \\ //**Auto-generate overlap**// This function resets all strip overlap defintions and will also generete all the possible strip-overlap models in all strip-overlaps (see 'Auto-generate coupls'). \\ \\ //**Detailed Strip Overlap Definition**// Select a strip overlap in the column 'Strips with overlap'.\\ This will fill in the 2 right hand sided columns. * Models in strip-overlap: shows the models in strip overlap, couples build with one photo coming from one strip and the other photo coming from the other strip. * Photos: shows all the photos assigned to the strips from the selected strip-overlap. {{stripoverlap2.png?nolink&750|}} If necessary, you can change a selected strip-overlap configuration: \\ \\ **//Add model//** * Select in the column 'Photos' two photos that form a strip overlap couple. Take care that each photo is belonging to a different strip. * Press the button 'Add model' to add this strip overlap couple to the selected strip-overlap. \\ **//Remove model//** * Select a model in the column 'Models in strip-overlap'. * Press the button 'Remove model' to remove this model from the selected Strip-overlap. \\ \\ **//Show unassociated//** After removing models from the selected strip-overlap, you can show the photos that are now free and not used yet in a strip-overlap. In this way you can easily find these photos and use them eventually to add models. \\ **//Auto-generate couples//** When you have removed models, this button will recalculate the possible models in the selected strip-overlap.
