Equirec2Perspec is a python tool to split equirectangular panorama into normal perspective view.
Given an input of 360 degree panorama
Split panorama into perspective view with given parameters
import os

import Equirec2Perspec as E2P
if __name__ == '__main__':
equ = E2P.Equirectangular('src/image.jpg') # Load equirectangular image
#
# FOV unit is degree
# theta is z-axis angle(right direction is positive, left direction is negative)
# phi is y-axis angle(up direction positive, down direction negative)
# height and width is output image dimension
#
img = equ.GetPerspective(60, 0, 0, 720, 1080) # Specify parameters(FOV, theta, phi, height, width)
