Waveshare CM4 Alternative with NPU and Visual Processing Core

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:/...

Re: raspbian bullseye and stereomode

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

Re: raspbian bullseye and stereomode

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...

Libcamera Dual Cam Support

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.

Re: raspbian bullseye and stereomode

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...

Re: raspbian bullseye and stereomode

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! 🤣

Re: raspbian bullseye and stereomode

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.

Re: Install SLP on Ubuntu?

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 :)

Re: Install SLP on Ubuntu?

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 :)

Re: Install SLP on Ubuntu?

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 ...

Install SLP on Ubuntu?

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
