Skewed Cameras/Photos

[kikbak]

Hello,

1) The attached images show 3 individual flight lines.  Two of them are adjacent and appear to be well aligned during sparse point cloud creation.  The third flight line which is nearby but not adjacent to the others appears to have a large amount of skew/tilt when compared with the others.  I also attempted to align the photos in the third flight line independently but they still appear tilted.

2) Another strange thing I'm encountering is that some imported images within the flight lines are showing negative altitude values.  I checked with the source data EXIF and the data appears to all be positive values.  Some of the negative altitude photos will align but others will not.  Is there an explanation for this phenomena?

Thanks

Hello kikbak,

Could you please send us this project file to support@agisoft.com?

Problem may be related to the lack of overlap between flight lines.
