I appreciate it. I read answers and look here(http://www.ros.org/wiki/cv_bridge/Tutorials/UsingCvBridgeToConvertBetweenROSImagesAndOpenCVImages)
There is "ROS passes around images in its own sensor_msgs/Image message format."
But "sensor_msgs/Image message format" has uint8[] data.(http://ros.org/doc/api/sensor_msgs/html/msg/Image.html)
Is it wrong? I know depth data is 11bit data. I think "sensor_msgs/Image" is encoded and it loss some information.
It convert ROS image to OpenCV image.
Loss image converted also has loss information. Is it right?
So I want to get 11bit raw datas. What can I do?
