ROS2 node for the Raspberry Pi Camera Module. Works with both the V1.x and V2.x versions of the module. We recommend using the v2.x cameras as they have better auto gain, and the general image quality is better.
This is built as a stand-alone package. So, presuming one followed the instructions for building ROS2 with the usual defaults:
cd ~ source /opt/ros2/setup.bash git clone https://github.com/Misterblue/raspicam2_node.git cd raspicam2_node ament build .
Running the Node
Once built as above, the commands to run are:
cd raspicam2_node source install/setup.bash ros2 run raspicam2 raspicam2_node
