CHI@Edge Peripheral Types

Peripherals require explicit device_profiles during container creation to map physical hardware paths into the container namespace.

For example, a camera might require /dev/video0. The device profile "pi_camera" makes /dev/video0 (among others), get passed from the host device into your container.

Vision and Imaging

Raspberry Pi Camera

Support for official Raspberry Pi Camera modules (v2, v3, and HQ).

• Device Profile: pi_camera

• Driver Stack: Uses the libcamera stack. Legacy raspistill/raspivid tools are deprecated in favor of libcamerastill and related. The following artifact and git repo provide a docker image with necessary drivers pre-installed.

• Artifacts:

  • Trovi: Camera Peripheral Example

  • GitHub: edge-picamera-image

• Specs: Raspberry Pi Camera Documentation

• Device Nodes mapped:

  • /dev/video0 - /dev/video31

  • /dev/media0-4

  • /dev/vchiq

  • /dev/dma_heap

Pi Camera 3

• Sensor: Sony IMX708

• Autofocus

• 12MP

• Specs: https://www.raspberrypi.com/products/camera-module-3/

Note: The Pi Camera3 needs both the pi_libcamera and the pi_camera3 device profiles. This is because it exposes additional interfaces under /dev for things like autofocus. Upcoming work on peripheral management will remove the need to do this.

Pi Camera 2.1

• Sensor: Sony IMX219

• No Autofocus

• 8MP

• Specs: https://www.raspberrypi.com/products/camera-module-v2/

Wide Angle 160 OV5647

• Sensor: OV5647

• 5MP

• No Autofocus

• Datasheet: https://files.seeedstudio.com/wiki/OV5647_Series_Camera_Module/OV5647-160_FOV_IR_Camera_module.pdf
