I have a MotoG6 phone and I need to find out the exact sensor width (trying out photogrammetry, it's pretty cool but Meshroom requires a sensor width, and it'd work a lot better if I didn't have to just guess).

The focal length is 3.95mm. Here's some other possibly usable(...?) information a different (worse) photogrammetry software had as a automatic calibration for the camera:

  • Have you tried contacting the manufacturer ? – StephenG Apr 8 '20 at 5:22
  • Technically, you can't; There is usually a relationship because the angle of view has to be roughly the same in all cameras but there is enough variation to make the computation imprecise. – xenoid Apr 8 '20 at 8:27
  • What are the pixel dimensions of the images? (e.g. 4000x3000, or 4624x2601, etc.) – Michael C Apr 8 '20 at 14:42
  • I once was searching for some kind of database which gathers the sizes of the different sensors in order to run some batch photogrammetry computation from different sources; photo.stackexchange.com/questions/101912/… I finally have to search (sometime the information is hard or even impossible to find) on the manufacturers' website or googling with; 'teardown + camera model name'. Hope it can help for future investigations. Good luck with that. – s.k Apr 19 '20 at 19:43

MAIN CAMERA Dual 12 MP, f/1.8, 1/2.55", 1.4µm, PDAF 5 MP, f/2.2, (depth) Features Dual-LED dual-tone flash, panorama, auto-HDR Video 1080p@60/30fps

SELFIE CAMERA Single 8 MP or 16 MP, f/2.2, 1/3.1", 1.0µm Features LED flash Video 1080p@30fps

  • That 1/2.55" looks like something, could be sensor width but what does the 1/ in front of it mean? – Mowkitty Apr 8 '20 at 6:29
  • It means the diagonal of your sensor is 1/2.55 inch. It's simple division. Each Pixel has 1.4 micrometer side length – planetmaker Apr 8 '20 at 7:02

    @planetmaker That is not correct. See photo.stackexchange.com/a/24954/1943 – mattdm Apr 8 '20 at 7:17
  • Interesting! Thanks for that link – planetmaker Apr 8 '20 at 12:08
