@PixLab, I used this settings (example with squares after deformation) :
@Ofnuts, I know how the perspective transform work, but in my case I saw after the perspective transform that the proportions of the black door on the left side was't in proportion to the real scene, so after cropping the very big result, I scaled the picture so that the black door had the right dimensions. I saw that the picture from left to right was logarithmic stretched so I searched for a solution and found the link to solve this with G'Mic-Qt. I often searched for such a tool when I make a panorama image and the proportions of the result are not right. This must do the job.

Used it on a extreme distortion with formule w*(2+1)*x/(2*w+x)

Not very detailed (but it can't in this example) but corrected after perspective correction with gimp :
Except that this particular case is really what the perspective transform is used for, because making the top and bottom parallel restores the scale.
