Re: Bottom-bottom camera orientation

Hi taa1, In your case one camera is rotated 90 clockwise, and another is 90 counterclockwise. It's tough to process this on the StereoPi side. In one of our experiments , we needed to rotate both cameras to the same direction, so "-rot 90" key can help. It's easier to manage this on the receiving si...

Re: StereoPi v2.02 (Slim) endlessly reboots on CM4 Lite

Hello DaAuron,

All the latest CM4 get the newer firmware version, which was incompatible with the software in our stock images.

Now, both SLP and OpenCV images have been updated and should work out-of-the-box.
We've also updated WIki links to images and update files.

Re: StereoPI ethernet connection to a raspberry pi 4B

You need to set a static IP address and network parameters for the direct Ethernet connection. If you're using SLP, please check the cosmostreamer.conf file. You can set static Ethernet parameters there instead of DHCP.

Re: Distance between Lenses?

The "default" distance is 65 mm since it's the average distance between humans' retinas.

You can adapt this to your task. The bigger the distance, the better results you have for far objects, but closer objects won't be detected on the depth map correctly.

Hello Ismud, Bookworm has a new video subsystem (libcamera) without stereoscopic support. We'll try to use libcamera, but it's challenging. You can use Buster, which has MMAL/raspivid/raspistill video stack. You can also download the ready-to-use Buster with the latest kernel and OpenCV installed: h...

Re: No camera feed visible and only one Camera LED illuminated

Try these commands in the console to check each camera:

raspistill -cs 0
raspistill -cs 1

Each command should show you a preview for each camera. It looks like one of them has an issue with the ribbon connection.

Re: Compatibility with NOIR wide v3

Hi wywarren,

You are right. All V3 cameras need libcamera-based approach, but our SLP2 is built on older MMAL subsystem. We are working on the newer version now.

As for the "green sticker OS" - it's SLP2, and you can find some more details on it in our Wiki.

Hi bwegge,

Your issue looks similar to [urlhttps://forum.stereopi.com/viewtopic.php?f=20&t=1335&p=3366#p3366]this one[/url].


I'm trying to emulate this to reproduce this error.

Re: Camera overlay

Arcturus you can capture two independent streams, one for each camera. After that, you can use GStreamer or another software to overlay one video frame on another. Since CM4 computational power and GPU is limited, you should optimize these part to get the result you need.

Hi Aur20,

The link to dt-blob.bin is sitting on the main Wiki page and named "dt-blob.bin for the CM3 and CM4". You can decompile it to see the DTS file.

Re: SLP2 image over-exposure - StereoPi V2

Hi peterfiabigron,

Are you using SLP2? Please share an example of the issue; I'll try to reproduce it and find the solution.

The last fix was done a lot of time ago, and as a result, Raspberry Pi Foundation made some fixes in their firmware to eliminate this. We may have a new issue here.

Re: Camera detected/supported 2, still no image

Hi Hansi, It looks like you have a connection issue. If some ribbon cable lines are not connected, both cameras can still be detected (since they are using just a few lines for this), but the full data exchange (for image or video transfer) is impossible. At first I'd recommend you to check which ca...
