Hugin doesn't return the offset pixels values

[João Pedro Carvalho]

Hello,

See the next lines:

It is possible to have the x and y offset values (in pixels) giving the Trx, try and trz?

No, this is not possible. Tr[xyz] don't describe a simple translation in 2D. Instead they describe a 3D translation of the camera (which can also be rotated), which does not translate into a simple offset.

Thank you for your answer. But when I run hugin executer, it gives me an ouput image ( with these two images) and I can see the offset between them. I know that the image could be rotated but it is also has a x / y offsets too. Do you know a solution to have these parameters?

Hugin calculates the non-linear transformation for each pixel separately. So there is no fixed offset and therefore can't be calculated.

Thanks again for the answer. However is not possible to to have a Rectangle to tell us the limits x and y?

Hello Joao,

may be you describe what the problem is, that you want to solve with
those values. Please also give some context.

Hello,

I just want to know the x and y limits of the second image in relation to the firt image, i.e. The max and min x y pixels values when the second image is rotated, transladed and scaled

[João Pedro Carvalho]

Hello, 

I already could find a solution and now I can find the x and y limits. Thanks again!
