Asus xtion pro live depth camera calibration error : ImportError: No module named camera_calibration.approxsync

edit

Hi,

ubuntu 12.04 and ROS Fuerte

I want to calibrate the ir camera of the Asus xtion pro live so that i can get accurate reading from the device.

When I tried I was getting the error given below..

Any suggestion

sai@sai-HP-EliteBook-8460w:~/fuerte_workspace$ rosrun camera_calibration cameracabrator.py --size 8x6 --square 0.108 image:=/camera/ir/image_raw camera:=/camera/ir/camera_info

Traceback (most recent call last): File "/opt/ros/fuerte/stacks/image_pipeline/camera_calibration/nodes/cameracalibrator.py", line 42, in <module> from camera_calibration.approxsync import ApproximateSynchronizer

ImportError: No module named camera_calibration.approxsync

Thanks
