This week I worked on reading the OpenCV documentation to get a better understanding of how to capture webcam input in python. I was able to find a Python script that allows us to get the webcam input and display it on screen and am trying to figure out the best way to overlay an image onto it. This will allow us to overlay a heatmap onto the camera input so that we can show where the signals are coming from. I also helped to debug the hardware that we were using. For some reason one of the outputs from the downconverter was quite a bit lower powered than the other and we figured out that when we swapped to the other downconverter we did not have this issue, it leads us to believe that something may be faulty with that board and it took a while to figure that out. Once we switched this board we did additional testing on the correlation/synchronization of the SDRs so to help with this I wrote an additional binary for the STM32 to tell the VCO to output a 150 MHz signal so that we could skip the downconverter in order to work with just the SDR’s.
This next week I will help the team integrate the remaining two SDRs and continue working on overlaying images to the camera feed in Python so that we can start getting to the final stages of our project.
