Re: SLP2 FAQ
Hey MJR2022, Older SLP V1 (i.e. slp2-0.8.19.img.zip) won;t work with StereoPi V2, since this version is old and doesn't know about CM4 existence. Thus it's not booting. Did you try to unarchive image file first, and record it to the eMMC then? Your screenshot says you're on Mac. I'm using Balena Etc...

Re: V2 (IMX219) camera module and SLP UDP stream?
Taki, could yoiu please define which model of the camera you are using?
The photo you've quoted has SE-SB01 cameras from Soho Enterprise (one of early prototypes), and needs a special dt-blob.bin
I will be pleased to help you with dt-blob after getting your camera model info

Re: StereoPi Issue - Right camera input displaying magenta in hotspots
Hi Taki, The magenta issue is usually belongs to Sony sensors, but you have OV5647. I guess in your case this is the "color disbalance" issue. I have two ideas here: 1. You can try to change the "metering mode". It defines which part of the image is used for the color detection. 2. If you have a cha...

Re: raspbian bullseye and stereomode
Hi Zoldaten, Huh, libcamera is still in the early stage... And the stereoscopic mode activation works another way. I can help you with two pieces of information: 1. Here is our first experiment of getting two images from two cameras using libcamera: https://forums.raspberrypi.com/viewtopic.php?p=196...

Hi atrunyan, I've spotted your "cutted" pairs looks swapped, i.e. left image is actually a right image.

Re: Use standard Raspi 4 instead of compute module?
Unfortunatelo nope. Classic RPi has the only camera connector (and a camera bus exposed). That's why we've created StereoPi, based on Compute Module.

Re: variable baseline
Hi stereospatrick, To get 1 meter baseline you have to use a couple of 50cm ribbon cables. You c an find them at any Raspberry-related store. In our experiments we were able to use 2m (two meters) ribbon cables, but this is a bit tricky. With this length of the ribbon cable it gets a lot of radio-em...

Re: Vertical Misalignment
Hi dnaman, If you are using StereoPi with OpenCV, then you can use calibration procedure. After that you'll get aligned images even if they were vertically misaligned. If you are using StereoPi for the stereoscopic photo, you can also use post-processing tools like Stereo Photo Maker. Take a look at...

Uh, it was the CM4 installation. Yup, installing it up to the sensible "click" is crucial.

Re: Splitting stereo video into two videos?
Hi atrunyan, I am also looking into how to give it my calibration camera info to get accurately sized models. - as I understand, you can use the built-in Agisoft calibration . I.e. just feed it up with calibration images, and it'll calibrate camera. I'm not familiar with Agisoft, but brief search sh...

Hi Triops, There is no magic in the case design. The main point is to have a good 3D drawings of all parts you'd like to design a case for. You can use these 3D models to do exact measurements for your enclosure. Here in the Wiki you can find the STEP file for StereoPi V2. For specific items (like c...

Re: How low power can the StereoPi v2 be?
Brief answer is 'nope'. You can force StereoPi to go to sleep mode (like any Raspberry Pi), but: 1. This mode is not reliable and require a lot of advanced software skills with understanding of hardware-specific things. We got no luck with this. 2. Even if you put compute module to this mode, we hav...

Re: calibrated principal distance vs focal length for 160FOV fisheye
Hi onestarhalfpoint,
I trust the OpenCV calculations but not the specifications declared on the website. To say more, you can find a few similar camera models from different manufacturers with dramatically different focal length numbers.

As for the Wiki - SLP2 getting a lot of updates and new features, and Wiki is a bit outdated (shame on me!). I'll update all screenshots and descriptions this week!
Thank you for spotting this issue!

You can't use H264 encoding to do this (resolution exceeds RPi GPU encoder limit), but can try MJPEG. W...

Thanx! All settings looks good to me.
Could ypu please share the "Menu -> Camera settings -> Camera" settings too?
We need to check the "preview" checkbox and "Preview opacity" settings.

Re: Can't connect to wifi network from SLP2 with error message
the simplest way to check is to update your router password (remove special symbols). If it works after that - this was an issue.
Could you please share these special characters here on the forum? I'm curious. Maybe we can try to isolate them somwhow.
