This MATLAB function converts the MATLAB image, img, to a message structure and stores the ROS or ROS 2 compatible image data in the message structure, msg.
In ROS2, the callback signature must be updated (or typedef'ed), and a pointer to node is used, rather than a NodeHandle. #include "rclcpp/rclcpp.hpp" #include "image_transport/image_transport.h" void imageCallback(const sensor_msgs::msg::Image::ConstSharedPtr & msg) { // ... } ...
