feature request : lens correction for uncentered, warped input image
Posted: September 12th, 2024, 11:39 am
Scenarios :
PWP could offer an enhanced "lens correction" tool that would accept this sort of image, thus
- A cropped images with visible barrel or pincushion distortion, while the full image is unavailable. The cropped image is not necessarily geometrically centered
- Panoramic image assembly ( outside of PWP ), sometimes results in a perspective view with barrel or pincushion, not necessarily geometrically centered
PWP could offer an enhanced "lens correction" tool that would accept this sort of image, thus
- Would detect and correct perspective warp
- Would determine the "virtual lens center" and perspective warp
- Would compute lens correction
- User could place points along a rectangular shape, potentially incomplete ( for example, missing one or two sides )
- User could place points along one or more straight line segments
