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:

  • \$\begingroup\$ 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. \$\endgroup\$

  • \$\begingroup\$ What are the pixel dimensions of the images? (e.g. 4000x3000, or 4624x2601, etc.) \$\endgroup\$

  • \$\begingroup\$ 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. \$\endgroup\$

1 Answer 1


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

  • \$\begingroup\$ That 1/2.55" looks like something, could be sensor width but what does the 1/ in front of it mean? \$\endgroup\$

  • \$\begingroup\$ It means the diagonal of your sensor is 1/2.55 inch. It's simple division. Each Pixel has 1.4 micrometer side length \$\endgroup\$ Commented Apr 8, 2020 at 7:02

    \$\begingroup\$ @planetmaker That is not correct. See photo.stackexchange.com/a/24954/1943 \$\endgroup\$
