Hi,
I got a GENX320 Event Camera and a RT1062 board recently. However, I’m not quite happy with the frame rate. The maximum fps I can get is around 160-180.
I just noticed that H7 Plus can provide a faster fps ~350. I’m wondering if there are any other boards that can provider higher fps for this event camera?
The H7 Plus is the fastest.
However, just to be clear here… you can set the frame rate for the sampling of events to whatever fps you want.
If you do sensor.set_framerate(1000) this will cause the camera to generate a frame every millisecond. However, the physical databus can’t output frames faster than 350 FPS on the H7 Plus (and ~175 FPS on the RT1062).
In any case, it’s not even possible to process frames this fast on the units. We’ve seen a lot of folks asking for the event mode support. I’m looking into adding this where you don’t have an FPS anymore… and it’s totally variable based on events. Once I add this then you’re not limited to any FPS.
But, in the current mode, pixels capture all events within the 1/framerate time. The event camera will never miss anything happening. If you see the framerate to 20 FPS for example… The image will contain the last 50ms of events happening. So, even if you wanted to see a very fast event in the image, it will be there. There’s no reason to have an extremely high readout rate of the camera. This just wastes CPU time.
For example, with the framerate set to 20 FPS… this gives plenty of time for the processor to process the event image. And even if there’s an event that happens in 1ms it will still be in the image.
