Unable to get the coordinates and send the value to another Raspberry Pi.

Hi,
I'm using OAK-D camera.
I'd like to get the coordinates and send the value to another Raspberry Pi.
How can that be achieved?

Hello uk0310 ,
You can get the spatial coordinates of objects with eg. RGB & MobilenetSSD with spatial data. After streaming them back to the host (I assume in your case RPi 1), you could stream them to second RPi via web, by eg. websockets. Tons of possibilities on this end, but it really depends on your application.
Thanks, Erik

Thank you for your reply.
I'd like to perform an object-detection and want to share the coordinates of the bounding-box (plus depth-information).
I could perform an object-detection and show the coordinates of the bounding-box (plus depth-information) in display by using depthai_demo.py.
but I could not retrieve the values.
If i retrieve the values, I'll send the values to another raspberrypi by using UDP communications.
Can I retrieve the values by using RGB & MobilenetSSD with spatial data?

My UDP communication program is mentioned below.
I could send a sample value by using this program.
So, I send the coordinates of the bounding-box (plus depth-information) by replacing "d" with the values.

Hello uk0310 ,
You can also retrieve these values (bounding box, spatial coordintes) from the depthai demo using callbacks.py file, see docs here - from the onNn() function. Same with the example I linked above, you will retrieve SpatialImgDetections messages that have bounding box and XYZ coordiantes inside them.
Thanks, Erik

Thank you so much!
