Hello everyone,
„Concerning Maximal Count: I think it’s important to mention that the value will not result in fewer lines, just move the color threshold for red down to this number. That means all image pairs with more than e.g. 1000 matches will also be red.“
Changing Maximal Count value can result in fewer lines and also the color scale is recomputed. You can see the illustration in the picture below.
„So Connectivity means how many “partners” each camera has?“
If one camera has less connections with the cameras in the virtual component, it is not included in this component. If the camera has let’s say max. 2 connections with the cameras inside one virtual component and the component connectivity is set to 3, then this camera is not attached to the component.
“Also, is it correct to assume that if Maximal Count is left blank, red will be the connection with the most tie points in this model?”
Yes, it is correct.
„But just as it’s important that single Virtual component is achieved @ default Component connectivity 4, how important is it @ default Matches count 100?“
Edge within one component has to have at least this number of matches. RC takes a feature, if this feature is visible in defined number of images (Feature consistency) and if the angle among the pairs of cameras is bigger than the angle defined by Apical angle, the matches count for the edge is raised by one. Matches are the features that suffice these two conditions.
You can also analyze only selection of images if the Analyze selection is set to ‘True’. You do not need to actually count the components, you need to see if there are gaps among them or if there are separate virtual components in any part of the model.
“Also Internal vs External edges vs Both?”
Internal edges are the edges inside the components, External edges are the edges outside components, the ones connecting individual components. If you use both, then you can see all the created edges (the grey ones are internal, the colored ones are external).
