Slow frame capture #233

Open dunfrey opened 6 years ago

dunfrey commented 6 years ago

Does anyone have an idea how I can do to speed up the capture of frames on my Udoo camera? what parameters can be tested and where can I find links that describe and explain these parameters?

My reported problem can be seen in this video: https://www.youtube.com/watch?v=QDRRXvCQDOw

The resolution used determines the frame rate that can be achieved.

The first thing to do is to refer to the camera sensor data-sheet:

This defines the upper bound of what the sensor should be able to achieve:

Beyond that of course there might be SVO parameters you need to adjust as well.

Which resolution are you using at this point?

Oops, thanks for your return, @laurentgauthier.

I'm using 30fps at 640x480. I've tried to increase this value, but the camera for some reason only changes to a smaller value, like 15fps. For larger values, I can not apply.

In addition to configuring the camera, what would be the settings I would have to do in svo? I can not find a solution to this.
