If distortions are occurring throughout the entire site and not just specific areas, the problem is most likely tied to the flight parameters. Following are some of the common causes and solutions to poor image stitching that are covered more in depth in this article.
- Image Overlap Settings: 80% side lap 85% front lap
- Angle of Camera: Double grid 60 degree flight and a single grid 90 degree flight
- Fuzzy input images: ISO setting of 100

Image Overlap settings
AirWorks recommends: 80% side lap 85% front lap
The amount of overlap from one image to the next image will directly affects how well images will stitch together when creating the orthomosaic. Not enough overlap will cause poor stitching will always equal poor data sets.

AirWorks recommends setting an 80% side lap and an 85% front lap to achieve the best results. More information on overlap settings can be found in the flight parameters page here: (link)
