Image -> real world coordinate transformation

SpirosMillas

Hello,

Im using the OAK-D-PoE camera and i have some questions. First, is it possible to access the cameras emmc to use as storage for photographs? My second question is regarding converting image coordinates to real world coordinates, i see that in a previous answer to a question similar to mine the following equations were given for the conversion

X Coordinate:
- X = ((x - c_x) * Z) / f
Y Coordinate:
- Y = ((y - c_y) * Z) / f

I was wondering if these equations here are correct and if so, how are they derived?

Thank you for taking the time to read through my question, any advice or knowledge is much appreciated!

Hi SpirosMillas

Update bootloader first
Check if you have EMMC - script.

SpirosMillas My second question is regarding converting image coordinates to real world coordinates,

it's derived from the pinhole camera model.

You can solve for Xc and Yc and get the above equation. X = ((x - c_x) * Z) / f

Thanks,
Jaka
