OpenMV TV Shield

I’m using an H7 Plus and considering mounting it on a drone platform. The platform’s flight controller (Lumenier F765) only supports analog video input. As I program the OpenMV to perform object detection, I’d like to overlay the detection results (bounding boxes, etc.) directly onto the video feed, so that I can view exactly what the drone “sees” during flight.

While I understand that this is typically done through the OpenMV IDE GUI, I’m unsure whether the TV Shield transmits only the raw video feed or if it can also carry the processed video with the object detection overlays. My goal is to view the annotated video in real time from the drone’s perspective, especially for testing detection accuracy at varying distances and speeds during flight.

Thanks for your help!

Hi, the TV shield outputs whatever the frame buffer is. So, like the IDE. You can use it to do what you want.

Just to confirm my understanding — if I’m overlaying detection boxes when an object is detected, will those superimposed boxes also appear on the video output through the TV shield?

Yes, you send whatever is in the frame buffer to the TV display.
