Well I don't know how to do cv::Mat_<cv::Vec3d> but this is what I do for a regular cv::Mat.
cv::Mat cv_image; // image from camera
cv_bridge::CvImage cvi;
ros::Time time = ros::Time::now();
// convert OpenCV image to ROS message
cv_bridge::CvImage cvi;
cvi.header.stamp = time;
cvi.header.frame_id = "camera";
cvi.encoding = "bgr8";
cvi.image = cv_image;
sensor_msgs::Image im;
cvi.toImageMsg(im);
