Description

I would like to add support for the Vexcel UltraCam Eagle Mark 3 sensor to the OpenSFM sensors database, but it seems to be a bit of an interesting case as it can be in one of four focal lengths:

  • 210mm
  • 120mm
  • 100mm
  • 80mm

It looks like the Camera Model EXIF tag is used to differentiate the different platform versions:

It also seems that the Title and Subject fields hold mirror-copies of extensive metadata:

Otherwise, the sensor's specs are the same:
26,460x17,004px resolution
4.0um pixels
RGBN

Specs Sheet:

How would one go about getting this added? I'm really not sure I understand what needs to be done for such a sensor.

Research direction

Start with the OpenSfM sensors database and inspect how Camera Model EXIF values select focal-length variants. Confirm the four focal lengths and the listed resolution, pixel size, and RGBN specifications against the linked product page and spec sheet; done means the Eagle Mark 3 variants are represented and recognized.
