How to fix distorted in photo 3D models?

To fix distorted photo 3D models, start by checking source photo alignment and feature matching, then use software to adjust mesh topology or reprocess with corrected camera data. Distortions usually stem from uneven photo coverage (retake missing angles), blurry features (enhance details), or wrong camera settings (update data). If issues remain, add a reference object (like a ruler) to photos for better alignment, or reduce overlapping shots slightly to avoid overprocessing.
