StereoPi V2 Heads to Crowd Supply with an Improved, Compute Module 4-Based Stereoscopic CV Board

New board includes a range of improved features, and has a Raspberry Pi Compute Module 4 at its heart.

Russian stereo computer vision specialist StereoPi is preparing to launch a crowdfunding campaign for a second-generation iteration of its eponymous Raspberry Pi-powered open source camera platform — and it's based around the freshly-launched Raspberry Pi Compute Module 4.

"Thanks to the newest Compute Module 4, we have a bunch of new features to introduce," the organization explains of the upgraded StereoPi V2 design. "With the new SoC module from Broadcom, you have up to twice the speed in your OpenCV Computer Vision and DNN applications! And the fast DDR4 memory will add more speed to your memory-intensive applications (e.g. video capture and processing)."

"Thanks to the dedicated 1Gbit Ethernet on the new Compute Module 4, there is no more compromise between the USB speed and Ethernet bandwidth! If you are planning to use the StereoPi in industrial solutions, you can choose the eMMC equipped Compute Module 4. This fast and reliable storage is available with 8, 16, or 32Gb options!"

Other improvements in the new design include USB Type-C for power, alongside a JST connector for hot-swappable battery use and Power over Ethernet (PoE) support, "dev board" features that puts I2C and other lines on the board with zero-ohm resistor gaps for signal hacking, and a new power management system supporting up to 4A of current.

The software side of the system remains largely unchanged, offering a native stereoscopic mode in Raspberry Pi OS and with the same 65mm distance between the two CSI camera connectors. As before, there are two USB Type-A connectors and a four-pin male USB header on the board, and the design remains open source. The group has also promised to release new tutorials, including virtual and augmented reality, an OpenCV-based point cloud tutorial, and support for the Oculus Quest virtual reality headset.

More information is available on the StereoPi Crowd Supply page, along with a link to be alerted when the campaign goes live.
