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.

Re: SLP2 image not working. Any suggestions?

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.

Could you please run this command and share the result with us:

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...

Hi,

Having a similar issue to this, after updating to latest firmware through SLP2 I can no longer access it in browser. Camera still streaming fine to monitor.
Which SLP2 version do you have?

Re: HDMI output to Oculus DK2

Hi iPutBack, I have no DK2 nearby to test, so I can't confirm the settings. Did you happen to try to test this config using regular Raspberry Pi 4? (Pi3 is not good, but RPi4 has the same CPU as CM4). ENOSPC means insufficient video memory; you can try to increase GPU MEM in config.txt Also, did you...

Re: Video playback? speed problems

Gábor thank you very much for this catch!

As for V3 - we are working on this. It's not that simple, since V3 camera is not supported by MMAL video subsystem we are using in SLP. It requires new libcamera-based video stack, which has no stereoscopic out of the box...

Re: Raspberry camera modul 3 with autofocus

V3 camera is supported by the new video stack (libcamera), and is not supported by old (MMAL) stack used in SLP2. It means you can use V3 with Python (new OpenCV image coming soon), but SLP update will take a long time. Old stack was optimized for stereoscopic capture and has a lot of other good stu...

Re: SLP2 and CM4

Hi Guillaume,

Uh... I had never faced an issue like this. I'll try to find CM4108032 to test this. It looks like 8Gb has some specific EEPROM, which requires kernel update in SLP.

Re: camera angle question

Yes, but there are better options. You see, each sensor has a 4x3 side ratio. By rotating it, you'll have 3x4, i.e., your image will be narrower, and image width is more important for the depth map than its height. You can rotate each image 90 degrees after cutting the stereoscopic pair. This requir...
