DESCRIPTION

 

 

Binocular Stereo Vision Expansion Board For Raspberry Pi Compute Module CM3 / CM3 Lite / CM3+ / CM3+ Lite, Provides Multi Expansion Ports, Small Size

BINOCULAR VISION EXPANSION BOARD

Dual Cameras Support, Play Around With Raspberry Pi Binocular Vision Projects

for Raspberry Pi Compute Module CM3 / CM3 Lite / CM3+ / CM3+ Lite

 

This binocular stereo vision expansion board is specially designed for Raspberry Pi Compute Module, compatible with CM3 / CM3 Lite / CM3+ / CM3+ Lite. It features three camera ports and common used ports like DSI and USB, more other peripheral interfaces are also supported through the FPC connector, all in the small size body.

By connecting with various sorts of cameras, combined with the included IMU fill light board, it is easy and flexible to build different Raspberry Pi stereo vision projects such as binocular parallax ranging, facial identification, living object detection, VR video recording, and so on.

Designed For Compute Module

Supports Raspberry Pi Compute Module CM3 / CM3 Lite / CM3+ / CM3+ Lite

Using With Camera

Connecting With Single Camera

directly plug into CAM0 port (enabled by default), OR plug into CAM1/CAM3 port (enabled by GPIO38)

Connecting With Dual Cameras

it is recommended to use two identical cameras (with the same FOV, distortion, focal length, etc.)

Working With Raspberry Pi LCD Display

Directly Connecting With Raspberry Pi DSI Display, Via The Onboard DSI Port

Also Supports HDM1 Display, Via The HDM1 Adapter

Tripod Support

Comes With Acrylic Mounting Plate To Use With General Tripod

The DSI Display, IMX219 Camera, and Tripod in photo are NOT included.
