Hi,

UBUNTU 12.04 and FUERTE

I am following the tutorial on calibrating kinect at http://www.ros.org/wiki/camera_calibration/Tutorials/MonocularCalibration

I am getting the following error

I have cv_bridge installed and I also rosmake it

sai@sai-HP-EliteBook-8460w:~$ rosrun camera_calibration cameracalibrator.py image:=/camera/rgb/image_raw camera:=/camera/rgb --size 5x4 --square 0.0245 Traceback (most recent call last): File "/opt/ros/fuerte/stacks/image_pipeline/camera_calibration/nodes/cameracalibrator.py", line 52, in <module> from camera_calibration.calibrator import cvmat_iterator, MonoCalibrator, StereoCalibrator, ChessboardInfo File "/opt/ros/fuerte/stacks/image_pipeline/camera_calibration/src/camera_calibration/calibrator.py", line 40, in <module>

import cv_bridge

ImportError: No module named cv_bridge

Hi Sai, have you checked whether you included the cv_bridge in your manifest.xml?

ok...i ll try it later but as of now, i m trying to run a script at https://svncvpr.in.tum.de/cvpr-ros-pkg/trunk/rgbd_benchmark/rgbd_benchmark_tools/src/rgbd_benchmark_tools/add_pointclouds_to_bagfile.py and it gives me the exactly the same error No module names cv_bridge ...Any help ?

This issue with cv_bridge got solved when I added the path to cv_bridge.py to the python path of environment variables .... export PYTHONPATH=$PYTHONPATH:/opt/ros/fuerte/stacks/vision_opencv/cv_bridge/src/cv_bridge

If the same error occurs with image_geometry, then just remove import image_geometry. For calibrating ASUS replace the /camera/rgb/image_raw with /camera/rgb/image_mono in the rosrun camera_calibration cameracalibrator................
