Python: Extracted texture has wrong rotation

[MatthewCaruana]

I was following and building upon your face fitting example (for Python) while also making my own implementation. When trying out your example code I decided to do the following in addition to the code that is provided in the demo.py file:

eos.core.write_textured_obj(mesh, "models/test.obj")

image = cv.imread('Images_Final/image_0010.png')
isomap = eos.render.extract_texture(mesh, pose, image)

cv.imshow("image", image)
cv.imshow("isomap", isomap)

cv.waitKey(0)
cv.destroyAllWindows()

The results that came with these commands (specifically the extracted texture) is the following:

As can be seen, it is orientated wrongly. I am using the latest pip version of the package, however, I also tried using 1.0.1 version as was discussed in #129 with the same result. Inherently, when I apply the texture to the model through MeshLab, it is keeping the same rotation as can be seen below.

Is there some sort of function that I have forgot to implement or call?

Hi,

As you can see, the texture map is just 90° rotated. You can probably just rotate it and it should be fine.

I think this was an issue in the Image Python bindings which I fixed recently in the devel branch: https://github.com/patrikhuber/eos/compare/devel

Let me know how that goes. Thanks!

Managed to acquire the rotated texture map. Sorry I did not try out the devel branch binding as I am running rather tight on getting things done with my studies.

Great!

I'll leave this one open until the changes from the devel branch are merged.

This has now been merged into the master branched (dc0fce864caf87648ac116d8ca1b2cf55435b65a) and released in eos 1.2.0/1.2.1! :-) Thanks again for pinging me on this issue here.
