Hi,

What are the units for each of the specified model parameters output by Lens?

• Focal Length

Thanks!

Hello vonah001,

Focal length and principle points coordinates are in pixels. You can find the detailed description of the distortion model used in Agisoft Lens and PhotoScan on the last page of Lens manual:
