Hello guys,
Thank you very much for bringing up this issue. It is the best way how we can find out that we need to make the help section clearer about this feature. We are sorry for the misleading information and inconsistency.
The full and correct extent of answer is as stated in the RC App Help. „The edge color is blue-to-red indicating how strong an edge is - more features, more red.“ is correct. If the edge is red, it means that it is the strongest one.
We will correct the information in the Quality assessment tutorial and we will also try to improve the description of this tool in the application Help.
To answer the Gӧtz’s question about the difference between Minimal matches and Matches count, this is how it should work:
Matches count and Component connectivity define how the cameras are connected into virtual components.
Component connectivity –from Help section – “Every two different components would have less (component connectivity) edges in-between.” If there are at least this number edges between cameras, then those cameras are connected into one component (two components are not created).
Matches count – two cameras are connected into one component only if there are at least this number of common features (matches) among those two cameras. Those features however have to suffice the condition defined by apical angle and Feature consistency.
Minimal matches – edges with the number of features lower that this value are not displayed at all. Edge with this number of features is displayed with dark blue color.
Maximal matches – if set to zero, all edges are displayed. The edge with the highest number of features is displayed with dark red color. If you set the specific value, then it is the greatest number of connections between two images. Color scale is recomputed accordingly to minimal and maximal matches.
The most important thing to check with Inspect tool is the number of created virtual components with the component connectivity set to at least 4. This means that if the images are connected into one virtual component with the component connectivity set to at least 4 (that is the reason why the default value is 4), the alignment can be considered as stable and no cracks or misalignments should appear. If there are several virtual components created than the connection among the cameras from these separate components is not that stable and we would recommend to add images in these areas.
