Honestly, these inputs are not ideal.
How did you merge the opposite components? Did you realigned the images or used another tool?
This could be a result of misalignments. It could help when you will do another camera paths with different angle or the height of capturing, or will be pointing also to the side:
Also, I think it is not needed to have 0.5 interval between images, as the ideal overlap is around 75% (but it should be side overlap).
