I'm a pi noob, but am using a raspberry pi 3 for a research project. We are trying to use raspistill to capture timelapse images from within a python script that we run at start-up. When we call raspistill (even directly from the command line), we struggle to achieve even 1.5 frames per second before it starts skipping frames. We'd like to get at least 1fps for our application. I'm using the following command:
Code: Select all
raspistill -n -r -awb off -awbg 1,1 -ss 4000 -ISO 100 -t 60000 -tl 1000 -o "image-%04d.jpg"
From looking at other posts, it seems like we should be able to capture with 1fps with no problem. Any advice as to how I can improve performance of our system to get that frame rate up?
I used NOOBs to set up raspbian on the sd card. I've used top to see if there were other programs taking up considerable resources (since our script should really be the only thing running) and didn't see anything substantial.
I've also tried using nice to set a very low priority for raspistill, but that didn't seem to help much.
Any assistance would be greatly appreciated!
