QUESTION

Missing info.plist file for C++ command line tool application within Xcode

Asked 2019-Nov-20 at 15:23

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.

You can embed an Info.plist in your binary by setting Create Info.plist Section in Binary and setting a path to your Info.plist file in Xcode > Target > Build Settings > Packaging (changes marked in bold):

Your Info.plist might look like this:

First 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

So 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.

In your code you have:
