Hi all,
I'm trying to perform a calibration of a stereo usb camera using the usb_cam drivers. I am following the proper tutorial on the ROS wiki page (http://wiki.ros.org/camera_calibration/Tutorials/StereoCalibration).
My stereo camera is publishing left and right images over ROS (/image_raw), I can run the calibration node and I'm able to perform the acquisitions of the samples. When I push the "Calibrate" botton, not so long after it appears this error:
Traceback (most recent call last):
File "/opt/ros/indigo/lib/camera_calibration/cameracalibrator.py", line 244, in on_mouse self.c.do_calibration()
File "/opt/ros/indigo/lib/python2.7/dist-packages/camera_calibration/calibrator.py", line 1052, in do_calibration self.cal_fromcorners(self.good_corners)
File "/opt/ros/indigo/lib/python2.7/dist-packages/camera_calibration/calibrator.py", line 855, in cal_fromcorners flags = flags)
SystemError: new style getargs format but argument is not a tuple
The roswtf command returns no errors or warnings.
I'm using ROS Indigo running on Ubuntu 14.04 and I just started using the ros framework so I'm not an expert at all.
The cameras I'm using are two ODROID USB-CAM 720P.
Can you please help me to figure out how to solve this isssue?
Greetings.
