StereoPi Forum

Waveshare have announced a CM4 compatible board which may be a wonderful upgrade for Stereo Pi v2. It includes a quad core CPU, dual core GPU, a neural processing unit for machine learning and some kind of hardware vision processing pipeline. Will be interesting to play around with for sure. https:/...

OMFG I'm an idiot! It turns out that setting the stamp on the image messages was somehow breaking everything!

I'm guessing for the side by side feature in picamera it did something under the hood to sync them that it hidden in the broadcom stack somewhere then? These camera modules are the ov5647 waveshare g type, I don't suppose you know of a guide for doing the hack on these do you please as I've not been...

I've just come across this thread in which there are lots of details regarding adding dual cam support to libcamera. I don't have the brain power to understand it right now but thought I'd share here before I forget.

I've taken a different tack and I'm trying to use CV2 to publish images from left and right, I'm using threading to run the two publishers in parallel and it's publishing fine. The problem is ROS is saying the images aren't sync'd. Even setting approximate sync it doesn't work. https://github.com/Ne...

Cool, I'll do some tinkering too. I can't imagine I'll have better luck than you but not knowing how anything works I may stumble on something by accident!

Any update on the libcamera testing please? I'm really starting to feel the pain of having to remain on the old 32bit OS is all, if there's an example script you could share for capturing simultaneous images on Bullseye 64bit I'd massively appreciate it.

Thankyou! I'll have a go and see what happens. Looks like you can run ROS in Docker on the Pi though so may be an easy win to switch to your image

Thanks, I'll have a look

Thanks Eugene, I'll remove it. I've got it working but with a few seconds lag, now I just need to reduce the lag

I've discovered a problem with the Ubiquity Robotics image, details here: https://forum.ubiquityrobotics.com/t/mmal-failed-to-create-camera-info-component/428/13 I can now at least record and capture video and images, working on getting streaming working now :) Edit: I used this command to get strea...

Hey Eugene, I'd be happy just to stream live at the minute, one or both cameras, I just cant get my head around the command line to pipe the output over udp. I can get a stream live but if I connect to it in the browser or vlc so a simple command line example would be incredibly handy. I'll try and ...

Howdo,

I'm trying to get my head around using the camera, I'm using the Ubiquity Robotics image to run my robot, and I'm wondering if it's possible to install SLP on Ubuntu or does it only run on the full image?

Thanks,
Keegan
