Hi,  
I would like to implement a stereovision system using actually three cameras, I saw some arducam systems [https://www.arducam.com/product/b0195-synchronized-stereo-camera-hat-raspberry-pi/](https://www.arducam.com/product/b0195-synchronized-stereo-camera-hat-raspberry-pi/) that allow building something with raspberry pi. I was wondering if I can achieve the synchronization using multiple OpenMV systems.

Thanks,  
Giacomo

There’s a frame sync pin on each camera that you can use to sync the video. That said, it’s not really that critical to sync each frame as our default camera is a rolling shutter camera. As such, we aren’t really movement invariant. If you are trying to detect something that’s moving fast you have to use the global shutter camera. Anyway, you can sync each camera to execute python code that triggers the camera capture with a master clock source if you use the global shutter camera.
