PanoTools NG:
Re: set of cameras for pano pictures

Thank you for the hints.
Letting Hugin do everything would be fine for me but it did not work in my test case.
I took 5 images, 0 degrees pitch, one per 72 degrees around the no parallax point. The images overlap about 50%.
I input the images in Hugin.According to cam specs: focal length is 2,73 mm (which Hugin also assumed), D(iagonal ?)FOV is 155 degrees.
Hugin assumed a Hfov(v) of 71,6
Cp detection missed to find CP between two overlapping images.I manually input the CP in the two overlapping images.I optimised (defalt: position, LDR).
In the assembler tab the calculated field (equirectangular projection) was 72 x 57.
The outcome was completely wrong.
I changed the objective from standard to fisheye, and input a Hfov closer to the cam specs: the results were not good but anyway Hugin detected CP in all the contiguous images and the outcomes were panos with some errors.
I assume that it would be important to to input proper data of the lcam lens.
Any hints?

If you can take a good, well overlapping set of images,
Hugin will work out the numbers for you, and for
YOUR lens, not just a "typical example" of your lens.
And you don't need to worry (too much)
about the no-parallax point for this calibration
as long as your subjects are a good distance away.
