I am building a camera array for photogrammetry using the Raspberry Pi Camera Module 3 that is newly available in my area in January 2023. I use Meshroom for photogrammetry and it has a database with camera sensor information. I'll need to add a new line for this new camera!

The cameraSensors.db file from the newest Meshroom-2021.1.0 contains these lines for older Raspberry Pi cameras:




Could someone please tell me what the line should read for the Raspberry Pi Camera Module 3 available in early 2023? My thought from the camera specs is immediately below, but I found that it didn't work. I still got the "Camera Intrinsics: Unknown" warning.


Here is the Meshroom warning when I tried to use images from the RP V3 camera intrinsics unknown for RP V3 cam

I tried other entries based on the text in the warning, but had no luck. Can anyone help get this entry correct for the Meshroom cameraSensors.db text file?

Thank you, DS

  • \$\begingroup\$ Hello, I used exiftool-12.61 to examine the metadata from a jpg image taken with the RPi Camera Module V3. I include that example image metadata below. From that metadata, I adjusted the Meshroom cameraSensors.db file to reflect the Make and Model as follows: 'Raspberry Pi;/base/soc/i2c0mux/i2c@1/imx708@1a;6.45;devicespecifications'. \$\endgroup\$ Apr 26 at 18:20
  • \$\begingroup\$ From the Meshroom manual (at the link you provided), they do make a suggestion that I could strip the rest of the metadata to avoid the issue "Meshroom asks to add camera info to database, even if it already exists." I will have to learn how to do that if I need to go that route. Thank you for your suggestions. Here is a link to the metadata from a single image.

In the documentation of Meshroom it says on the page on adding a camera:

You can add your own Camera and Sensor by adding a new line to the camerasensor.db located in ..\Meshroom-2018.1.0\aliceVision\share\aliceVision\ (you can use any text editor). Before editing the database, close Meshroom. Edit and save the edited file.

The format is:


As the sensor is indeed 6.45 mm wide (according to the specs) your suggestion seems correct:

  • \$\begingroup\$ Thank you Saaru. Unfortunately when I tried Meshroom with photos from the Raspberry Pi Camera Module Version 3, it did not recognize the images with the edit to the cameraSensors.dB we had discussed above. I have edited my original post to include the warning message from Meshroom. Best regards, TS \$\endgroup\$ Apr 23 at 10:40
