Need help for proper rectilinear projection of equirectangular panoramic image

南楼画角 提交于 2021-02-06 12:32:16
问题 With the algorithm below, when the projection plane is tangent to the equator (the center line of the equirectangular image), projected image looks rectilinear. But when the projection plane is tilted, (py0 != panorama.height/2), lines are warped. The two last "lines" in the algorithm below needs to be "rectified", in order to adjust px and/or py when the center line of the destination plane is not at the same level than the center line of the equirectangular image. // u,v,w : // Normalized

Circular Fisheye Image dewarp to flat image

问题 UPDATE as on 12 Nov 2015 I used PanoTools plugin with Photoshop and Hugin and played with all those parameters. End up i found the parameters for projection, HFOV and image output size that fulfill my lowest requirement. Parameteres: Processed Output: My question is then how can i convert all these parameters and values into C# algorithm coding so that when I provide the original image, i will get the corrected output image? Thanks a lot. I have a square image captured from a circular fisheye
