void imageCallback(const sensor_msgs::ImageConstPtr& msg) { //Programme }

int main(int argc, char **argv) { image_transport::Subscriber sub = it.subscribe("/camera/image_color", 1, imageCallback); image_transport::Subscriber sub_depth = it.subscribe("/camera/depth/image", 1, imageCallback); } The imageCallback subscriber to the camera; I have two cameras.

The question is how can I use imageCallback in the two differents subscribes, because in that way it doesn't work, I got the two camera's image in the same window = like Toggle images !!?

You could create a second callback function, or add an additional argument to your existing callback, and pass in additional data using boost::bind.

OK, this is I think the only way to do that using boost::bind. Thank you so much.
