I was lucky enough to organize my elementary school reunion recently, the class from 36 years ago. During the reunion, we tried to take a picture from our old yearbook. It looked fine at first glance, but many spots turned out to be either trapezoid in shape or completely distorted, so I decided to use a 2D image editor to fix it, and I’m hoping to achieve the result shown below. (Image has been blurred to protect privacy.)
The whole idea is to transform a distorted 2D photo into a distorted 3D model, straighten all the UV coordinates, fine-tune the aspect ratio, and save the final 3D image into a regular 2D picture. It’s meant to fix serious distortions like that of a waving flag, instead of simple trapezoids that are supposed to be rectangles. It usually happens when you try to take pictures of the pages in a book from a camera angle that will inevitably make the image distorted. I just happen to know how to use a 3D modeling software, to apply the concept, and use the right features to restore the distorted image back to its original form.
The goods about this method:
- Unlike the traditional way of editing 2D images, all it takes is a little drag and drop of your original image to the right spots on a 3D model, and it won’t change the continuity of the original pixels.
- Not much traditional image editing skill is required.
- An image with multiple distortions can be adjusted through UV mapping as well.
The bads about this method:
- Mastery of a specific 3D modeling software is required.
- Once a 3D model is finished and ready to be saved as a 2D image, its resolution may vary according to which 3D modeling software you use, because after all, a 3D modeling software is not specifically meant for editing 2D images. The final finished image might have a lower resolution than its original distorted image.
