Description

How does one go about adding something with multiple cameras with different optical properties and sensors?

For instance, I see the iPhone 12 is currently not in the sensor database.

It has two rear-facing cameras:

12 MP, f/1.6, 26mm (wide), 1.4µm, dual pixel PDAF, OIS
12 MP, f/2.4, 13mm, 120˚ (ultrawide), 1/3.6"

And one front-facing:

12 MP, f/2.2, 23mm (wide), 1/3.6"

What would the sensor database profile look like?

  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

Start by examining the existing sensor database entries and how OpenSfM represents cameras with differing optical properties; the issue provides the iPhone 12's three camera specifications as an example. Done would require an agreed profile shape or implementation path for multi-camera devices, but the issue names no file, entry point, or test.
