[ros-users] cv_bridge question

[Kevin Walchko]

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);
