Hello, i bought an OpenMV cam to do some ball tracking work. I use the cam connected to vvvv by internal serial port COM4 (or any ) and i experienced some kind of latency or lag when following my object (as shown in the joined gif). However when i use the OpenMV program in OpenMV IDE it works like a charm.
Serial datas are pretty light, hard to believe it could be a process issue.
Anybody has an idea? Maybe a better Serial port setting?
Increasing baud rate is not an option?
Edit: I see that the default value is 115200. So I guess baud is not the bottleneck, unless it has been lowered.
Edit 2: this document contains some info about baud, anyway. Fine, I got it. I’ll stop right here. Il’ll just add that there’s a way to calculate baud, it’s based on sampling and other factors. Ok, I’m going, bye.
Hello Joreg, the goal is to beam some effects following the ball movements. We use this camera: https://openmv.io/
Because it embeds some internal process like Circle detection (it works like such a machine vision oriented arduino).
The second cam is to show the latency.
