Fail to open up calibration window for stereo USB cameras
I used usb_cam driver to run two usb_cam nodes. They are:
/camera1/image_view /camera1/usb_cam1 /camera2/image_view /camera2/usb_cam2 /rosout
Topic includes: /camera1/usb_cam1/camera_info /camera1/usb_cam1/image_raw /camera2/usb_cam2/camera_info /camera2/usb_cam2/image_raw
Then I try to calibrate the camera1 first. I type this command: $ rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.108 image:=/camera1/usb_cam1/image_raw camera:=/camera1/usb_cam1
The calibration window opened.
Then I try to calibrate in stereo mode. I type this command: $ rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.030 right:=/camera2/usb_cam2/image_raw left:=/camera1/usb_cam1/image_raw right_camera:=/camera2/usb_cam2 left_camera:=/camera1/usb_cam1
It failed to open up the window. No error messages. Pls help.
