Problem in generation Equirectangular Panorama

[Avishek Kumar]

I have a set of 11 images, that i took from my smartphone. the smartphone was put on a tripod stand, and then maintaining an overlap of 30% between consecutive image frames images were taken. the images were shot such that the camera was facing each of the walls of the hall.

I installed Hugin in Ubuntu and tried to stich the images through the following commands:

1) Generate pto file

    pto_gen -o project.pto *.jpg
2) Find control points with cpfind, with celeste to ignore clouds

    cpfind -o project.pto --multirow --celeste project.pto
3) Control point cleaning

    cpclean -o project.pto project.pto
4) Find vertical lines

    linefind -o project.pto project.pto
5) Optimize position, do photometric optimization, straighten panorama and select suitable output projection

    autooptimiser -a -m -l -s -o project.pto project.pto
6) Calculate optimal crop and optimal size

    pano_modify --canvas=AUTO --crop=AUTO -o project.pto project.pto
7) Now create output

    hugin_executor --stitching --prefix=prefix project.pto

i wished to know how efficiently i could create the equirectangular panorama, with the command lines. are there any advanced set of parameters required in the command lines.
