Thermal Image Capture Altitude Recommendation

[Jeff_Brady]

I’ve got a Flir 640x480 thermal camera (non-radiometric) 9mm lens.  Has anyone experimented with created thermal orthomosaics as far as optimum altitudes assuming you are stitching the RGB JPEGS and not stitching using R-JPEGs with the embedded radiometric pixel data?  I thought I read due to the low resolution sensor combined with the wide angle lens, it’s easy to fly to low which causes issues in the stitching.

Hi Jeff,

Flying higher is recommended as it will be easier to find keypoints (similar to a book: you can find more distinct points when a book is moved away from your eyes than when it is closer to your eyes). Remember to fly with at least 90% frontal and side overlap.

We will also like to have more suggestions from our users.
