QUESTION
I want to create a camera calibration application with opencv for a university course. I have created a command line tool application on macOS High Sierra. Unfortunately it came without an info.plist file. My application crashes with the following error message:
CameraCalibration[2314:193066] [access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data. Program ended with exit code: 9
I have already tried adding a info.plist file and setting it in the applications' General tab. I have also added the NSCameraUsageDescription key and string. Unfortunately my application keeps on crashing due to the exact same error.

in your binary by setting Create Info.plist Section in Binary
and setting a path to your Info.plist

I am trying to calibrate RaspiCam Fisheye lens camera with OpenCV. I am using Python example code and the cheesboard row and column numbers are also correct but somehow I can not get a successful result. I have tested with a lso much of photos below you can see them. My source code: https://github.com/jagracar/OpenCV-python-tests/blob/master/OpenCV-tutorials/cameraCalibration/cameraCalibration.py
my chess board rows and columns: rows = 9, cols = 6
but does not get a successful result

Answered 2018-Jun-15 at 08:19First at all, as far as I can see your camera has fisheye optics, but it doesn't give all the surface of fisheye image (usually it is a circle inside black frame). The second. The code you are using is for usual camera or wide angle (90-110 degrees) It's not for fisheye (~ 180 degrees). Third. You can use source code URL link from HERE
QUESTION
I am trying to perform a stereo calibration of 2 USB cameras in order to perform depth map, but I fall on this error and I don't know how to solve. I would be really grateful to who would be able to help.
...ANSWER
Answered 2018-May-04 at 11:08So the error says:
error: OpenCV(3.4.1) D:\Build\OpenCV\opencv-3.4.1\modules\calib3d\src\calibration.cpp:3384: error: (-215) nimages > 0 in function cv::calibrateCamera
This means that you are passing empty list variables as the object points or as the image points.
