This scene is an improved version of this inital reconstruction: https://skfb.ly/ENRw Calibrated lens settings and some quick masking of the sky from all images produced more accurate camera positions. These two aspects are going into my list of requirements for working with fisheye images. This result is closer to what I was expecting for the camera orientations and path. The biggest problems were from not having adequate overlap of the bins, but I should have expected that from my rule of thumb for camera - subject distance... but that will come with more practise once I bed down the camera orientations.
