Camera calibration file /camera_info/left.yaml not found
Hi, I am using Snapdragon_Dev_Board(eagle8074/Snapdragon801) with Stereo Camera. Snapdragon_Dev_Board has Linux Linaro 14.04(pre-loaded). I have installed ROS-Indigo on top of it. I am running two nodes snap_cam_roshttps://github.com/ATLFlight/snap_cam... and dfs_ros_examplehttps://github.com/ATLFlight/dfs-ros-...
to get the disparity image, depth image and point cloud.
While I am launching the snap_cam_ros on [Snapdragon_Dev_Board + Linux Linaro 14.04(pre-loaded) + ROS-Indigo] environment , using:
roslaunch snap_cam_ros stereo.launch
it is showing the following error:
using default calibration URL
camera calibration URL: file:///camera_info/left.yaml
Unable to open camera calibration file [/camera_info/left.yaml]
Camera calibration file /camera_info/left.yaml not found.
[using default calibration URL
camera calibration URL: file:///camera_info/right.yaml
Unable to open camera calibration file [/camera_info/right.yaml]
Camera calibration file /camera_info/right.yaml not found.
How to resolve this error: Can anyone help me out?

Hi, I have not used this package before, but it looks like you are missing the intrinsic calibration file. You can follow the tutorial and create the intrinsic files if you do not have them in a another directory. http://wiki.ros.org/camera_calibratio...
http://wiki.ros.org/camera_calibratio... I have followed the above link to calibrate the stereo camera very carefully. When I executed the following cmd from host system/Linux PC(having ros_indigo) connected with snapdragon board having stereo_camera over wifi: 'rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.108 right:=/my_stereo/right/image_raw left:=/my_stereo/left/image_raw right_camera:=/my_stereo/right left_camera:=/my_stereo/left'
SO there is no any screen popped up for calibration I got some error:
