I am using opencv in ros electric with python using the new cv2
(import cv2) interface. I could not figure out how to convert images
in python (they are numpy arrays) to ros images (sensor_msgs/Image).
The ros package "cv_bridge" only supports IplImage to
sensor_msgs/Image conversion in python [1]. Is there already a
solution around? Am I looking in the wrong place?
