Texture mapping from 3 view based images

i am a student in medical device engineering and i’m interested in the use of VTK

I have 3d model with unwrapped UV and I have 3 images taken from 3 different angles in an equal light source.

I only want to stitch images to each other and the result should be like above.

the stitching of the issue caused by overlapping borders of images is not important I can handle that later.

the question is do I need to reconstruct the 3d Surface geometry for stitching images?
if yes , how to start to do this ?

in this topic, they mentioned this but not explained well the process.

the web page

if I sum how to combine 3-view based images to create texture?

thank you so much in advance
