Re: Set max resolution

Hi Eugene, to be honest, I am "misusing" the StereoPi in a certain way, as I primarily want to capture still pictures with two cameras at frames rate of min 1fps. As such, I am not running after stereoscopic analyses but "simple" continuous, full resolution capture (without preview) of pics with two...

Re: Set max resolution

Without checking your code, I can confirm that I experienced similar issues. As you described, I experienced regularly freezing of the compute module with a camera seemingly active (LED lit). One distince difference to your case is, that I pushed the frame rate up as much as I could. However, I ackn...

Re: Set max resolution

The USB ports offen lack power, sometimes limiting to 2 amps. The stereopi, however, might ask for mor than that

Re: Set max resolution

jlurban: What power supply are you using ? Via the USB or the pins? Do you encounter the same problem at lower resolution?

Re: Set max resolution

Realizator, thank you for your feedback. Unfortunately, the application of running "raspistill" applications by shell commands will not satisfy our requirements in terms of photo interval. As our intention is to use the StereoPi on a "fast" moving vehicle, we need minimum frame rates around 1 fps. T...

Re: Set max resolution

Hi Eugene, thanks for your prompt reply. I tried raspistill (e.g. raspistill -3d sbs -o "test.jpg" -w 5200 ) which works perfectly, however when it comes to Python, it blocks any attempt of increasing the width above the standard resolution Screenshot.jpg Maybe I am missing some specific tweak, but ...

Set max resolution

Hi, I've just started working on the StereoPi, which I want to use as double (still) camera setup on a Raspberry basis. Working on my Python scripts from other Raspberries, I found one important limitation by the maximum resolution originating probably from the camera drivers. It seems that the reso...
