Hi [amfram](https://dev.epicgames.com/community/api/user_profiles/tab-redirect/about?discourse_username=amfram),  
you can try principles from this article: [Tutorial: Banana Effect - What To Do If My Model is Bent](https://forums.unrealengine.com/t/tutorial-banana-effect-what-to-do-if-my-model-is-bent/790591)  
Mostly the option using precalibrated images (images with fixed calibration parameters)  
Also, capturing not just in two lines could help and using some control points.
