2014-04-15 16:50:29 -0500	commented answer	How can I get the metric distance from the topic "camera/depth/image_raw"? Thanks a lot.
2014-04-15 16:16:34 -0500	commented answer	Publish Kinect Depth information to a Ros Topic Thank you for your answer. May I ask a question that if there is a way to get the value(float) of each point on the depth/image_raw before we convert it in to a cvmat?
2014-04-15 16:12:16 -0500	commented answer	kinect opencv Thank you for your answer. May I ask a question that if there is a way to get the value(float) of each point on the depth/image_raw before we convert it in to a cvmat? (Python best)
2014-04-15 16:05:50 -0500	commented answer	How can I get the metric distance from the topic "camera/depth/image_raw"? Thank you for your answer.It really a good way to get the depth data. But others say that depth/image_raw(32FC1) contains depth data. "For using the depth image, it is important to note that is a 32-bit float for each pixel, corresponding to meters." My problem is how to get the value of each pixel?

2014-04-14 02:25:03 -0500	asked a question	How can I get the metric distance from the topic "camera/depth/image_raw"? I am learning turtlebot_simulator. I run turtlebot_gazebo. Then I subscriber the topic "camera/depth/image_raw" using Python. but How can I know the exact distance of each point from the depth image? I can print the information of the image.Like: frame_id: camera_depth_optical_frame height 480 weight 640 encoding 32FC1 I have seen some similar problems, but have not solved my problem.

2014-03-25 14:25:02 -0500	asked a question	How can I get the Image.data of sensor_msgs/Image in Python Hi , I am learning turtlebot_simulator with gazebo. I am trying to write a listener in python to subscriber the topic of 'camera/rgb/image_raw'. But I have problems in getting the Image.data for it is uint8[], I want to know how can I translate it into a normal matrix or image which can be dealt with. Thank you!
