Best Import Settings for Fisheye Images

I am having some success with using images extracted from a 360 degree video (example above).

There is some rather extreme distortion of distant objects, however. Objects in the distance are shrunken. 

I am hoping that I can partially solve that problem by using laser scan data.

QUESTION: What are the optimal import settings for fisheye images like the above image? (i.e. What do I put into the option boxes shown below?)

Hi, for fisheye images is recommended Division camera model. But RealityCapture does not work well with so extreme fisheye images.
Also in 1ds view click on images then click on group calibrations and click on all photos and use these prior settings for all images:
And in your case I would use image masks to mask the corner areas of the image:
