ok found the problem the sysmbol is not exported as alalek suggested on github

so your remap is equirectangular to the rectangular image right? / add new image to question post

oh no sorry if i the question is not clear :/ i need the rectangular image (like your image) to 1st img in the post

2017-09-30 07:14:39 -0600 commented question rectangular image as overlay on equirectangular 360 degree image

from a rectangular image to 1st image / updated the first post

yes i know how to build the equirectangular with the stitching the only proplem is how do the remap of the rectangular

maybe i need so,me more math skills http://rcrmn.github.io/2015/07/24/aft...

[611, 0, 611; 0, 611, 611; 0, 0, 1]

[3; 0; 0; 0] http://pasteboard.co/aPt3qps.png the output does not look like equirectangular, i used differnet D params to test :/

2015-12-18 05:21:00 -0600 commented question fisheye image to equirectangular

any idea how i can calculate the coefficients D for the fisheye::undistort?

2015-12-17 11:21:39 -0600 commented question fisheye image to equirectangular

here is the code i use to test http://lpaste.net/147286

http://lpaste.net/1929295611396358144 this is the calibration file from calib3d

2015-12-17 09:01:34 -0600 commented question fisheye image to equirectangular

i think it have nothing to do because the output image should be equirectangular not?

Hallo

calib3d camera calibration i get this undisort image after calibration input http://snag.gy/9W9gj.jpg out http://snag.gy/7YB4Z.jpg

Hello i think this does not help me because the output image is not an undisort image https://github.com/Itseez/opencv/blob...

2015-12-15 22:58:27 -0600 asked a question fisheye image to equirectangular

Hello

for stitching images i want transform a fisheye image to a equirectangular image like nona (hugin) in hugin i can do this

my fisheye has 80 degree HFov

pto_gen --fov=80 -p 2 test22_r.jpeg

http://lpaste.net/147153 hugin pro file

nona -o test22_r_equirectangular.jpg test22_r.pto

is this possible with opencv ? i look at detail::SphericalWarper but no idea how i can set the destination matrix for equirectangular

here is the input and output http://snag.gy/bmE15.jpg http://snag.gy/RLaSI.jpg
