  • I want to know how to lower the CPU usage of the program

Four OAK-D-POE units are being used simultaneously.
I am testing it using a demo program(depthai_demo.py, mono_preview.py, etc...)
The example program uses about 2025% of CPU per camera.
If 4 cameras are running, CPU usage is about 80% or more.
I also reduced the number of camera frames and tested other examples, but still saw high CPU usage.
I want to know how to use GPU or other ways to reduce CPU utilization
please reply. thanks

    Hello denny , so most CPU usage comes from streaming frames. If you don't stream frames (or stream lower size/resolution frames), host/computer CPU usage would decrease.
    Thanks, Erik
