Thanks for sharing the three quality reports.
The main issue seems to be that there are several blocks that get created in the project. Otherwise, there are some uncalibrated cameras, but these are mostly from one line that went diagonally through the project and from some images on the borders:
For ARROYO LOS BERROS:
Here only two blocks are created. If we look at where they were created, we see that these can be fixed by adding a few manual tie points (MTPs) between the two blocks and Process > Reoptimize (see here: https://support.pix4d.com/hc/en-us/articles/202560349):
For ARROYO LOS BERROS - 2DA OPCION:
Here there is a large amount of blocks because the “Accurate Geolocation and Orientation” calibration method was used. This constrains the position and orientation of the camera and resulted in the software not being able to connect different areas.
For ARROYO LOS BERROS - OPCION STD:
Here the difference I could spot with the first project was that the first project has the “geometrically verified matching” option selected, which seems to have improved the results.
Please post updates if you tried to add MTPs in in the project with two blocks, or if there is another issue with the project you would like to discuss.
