E-Puck Camera

E-Puck Camera

This ROS2 driver takes images from camera device located on e-puck2 robot. It uses V4L2 driver for extracting the images from the camera and Multimedia Abstraction Layer to perform fast JPEG conversion by utilizing onboard GPU.

Parameters

quality Quality of JPEG conversion (default 8)
interval Interval of image acquisition in milliseconds (default 80)
width Width of the output RGB images, height is automatically calculated (default 640, valid values [640, 320, 256, 128, 64])

Topics

/image_raw [sensor_msgs/msg/Image] Raw RGB images
/image_raw/compressed [sensor_msgs/msg/CompressedImage] JPEG compressed images
/camera_info [sensor_msgs/msg/CameraInfo] Information about the camera (e.g. intrinsic parameters)

There a few things to note here, mainly related to Raspberry Pi Zero computational power and WiFi bandwidth.

Images will be published only if there is at least one subscriber to avoid unnecessary computation.
Topic /image_raw/compressed is suitable for offboard processing since the data transmission rate is significantly lower.
Topic /image_raw is suitable for onboard processing since no conversion is needed (much lower CPU utilization).
If you have multiple nodes subscribed to /image_raw/compressed it would be handy to have an additional node republishing images to reduce network utilisation, e.g. ros2 run image_transport republish compressed in/compressed:=image_raw/compressed raw out:=image_raw/uncompressed.
