I have the vision data I need, now what

I have a script that outputs the data I need from the image. It currently puts it out to the serial console. Is there a way to forward that to a local script or a virtual serial port?

What are my options for acquiring he data stream that comes out of the H7 for post processing?

Just use the uart module to output the data on an I/O pin to another microcontroller or directly control pins yourself. See the pyb module: http://docs.openmv.io/library/pyb.html?highlight=pyb#module-pyb

So no way to get it right from the IDE?

When you stop using the IDE once your app is done any program that opens the VCP UART of the camera will receive the print data the camera is printing.
