basic_bot.commons.camera_picamera

Camera Objects

class Camera(BaseCamera)

This class implements the BaseCamera interface using Picamera2.

To use the Picamera2, you need to be running on a Raspberry Pi Bullseye or Bookworm with a ribbon cable camera module installed.

To use with the vision service, you need to set the environment variable BB_CAMERA_MODULE=basic_bot.commons.camera_picamera before the vision service is started. You can al

- name: "vision"
  run: "python -m basic_bot.services.vision"
  production_env:
    BB_CAMERA_MODULE: "basic_bot.commons.camera_picamera"

By default the vision service uses opencv camera capture which ATM works on Bullseye and Bookworm with USB camera, but not for ribbon cable cameras. See also the Installation Guide for Bookworm.

Direct Usage:

from basic_bot.commons.camera_picamera import Camera

camera = Camera()
# get_frame() is from BaseCamera and returns a single frame
frame = camera.get_frame()
# you can then used the image frame for example:
jpeg = cv2.imencode(".jpg", frame)[1].tobytes()

See vision service for another example usage.

frames

@staticmethod
def frames() -> Generator[bytes, None, None]

Generator function that yields frames from the camera. Required by BaseCamera
