Hi,
i am using this project to calibrate my stereo camera.
I have successfully make cam_left.yml and cam_right.yml through-
"./calibrate -w 8 -h 6 -n 165 -s 0.108 -d "../calib_imgs/right/" -i "right" -o "cam_right.yml" -e "png""
"./calibrate -w 8 -h 6 -n 165 -s 0.108 -d "../calib_imgs/left/" -i "left" -o "cam_left.yml" -e "png""

but for stereo_calibratio "./calibrate_stereo -n 165 -u cam_left.yml -v cam_right.yml -L ../calib_imgs/left/ -R ../calib_imgs/right/ -l left -r right -o cam_stereo.yml"

it is throghing error-
terminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(3.4.2) /home/rahul/opencv/opencv/modules/imgproc/src/color.hpp:253: error: (-215:Assertion failed) VScn::contains(scn) && VDcn::contains(dcn) && VDepth::contains(depth) in function 'CvtHelper'

Aborted (core dumped)

Any suggestion?
I have collected the stereo images through ROS. "http://wiki.ros.org/camera_calibration/Tutorials/StereoCalibration".
Thanks.

Hi,
It is solved.
I have to change the raw input pixel format to mjepg.
