No disparity image with rotating detergent
Hi,
I am following the ChoosingGoodStereoParameters tutorial and receiving some errors.
At the end, all three image viewers (left, right, disparity) have blank images. How do I get the bag file to play correctly and which commands should I use to get the viewers to work properly?
Using the tutorial, the steps I did after downloading the rotating_detergent.bag file were:
rosbag reindex rotating_detergent.bag
rosbag info rotating_detergent.bag
The output of 'rosbag info' looked the same as that shown in the tutorial.
Next, I did
ROS_NAMESPACE=narrow_stereo_textured rosrun stereo_image_proc stereo_image_proc
rosrun dynamic_reconfigure reconfigure_gui
and the parameters were identical. After that I did
rosrun image_view stereo_view stereo:=narrow_stereo_textured image:=image_rect
rosbag play rotating_detergent.bag -r 0.1
and the three image viewers open with blank images. In the terminal where 'rosbag play' is running there are several error messages with contents
[ERROR] [1305607385.588706440]: Client [/narrow_stereo_textured/stereo_image_proc] wants topic /narrow_stereo_textured/left/camera_info to have datatype/md5sum [sensor_msgs/CameraInfo/c9a58c1b0b154e0e6da7578cb991d214], but our version has [sensor_msgs/CameraInfo/1b5cf7f984c229b6141ceb3a955aa18f].

Can anyone else run that tutorial and see images displayed correctly? Any hints on why this might not work or how to fix the checksums?
Thanks, Maxi
