StereoPi V2 is an open-source stereo camera based on Raspberry Pi CM4.

It can do all usual stuff like capture, save but can also do livestream, and process real-time stereoscopic video and images.

StereoPi can be used in various applications like in robotics, AR/VR, computer vision, drone instrumentation, panoramic video, etc.

Their previous version StereoPi was also crowd funded on crowd supply and was very successful.
