It took me a while to figure out what was meant with OpenCV Error: Assertion failed (i < 0) in getMat While searching for this error message I found [a list of error messages](https://adventuresandwhathaveyou.wordpress.com/2014/03/14/opencv-error-messages-suck/) which also explained what the problem was: The data type for `rvecs` was not a simple `cv::Mat` but a `std::vector<cv::Mat>`. After I fixed that, I got the next error message: OpenCV Error: Assertion failed (ni > 0 && ni == ni1) in collectCalibrationData, file /build/buildd/opencv-2.4.9+dfsg/modules/calib3d/src/calibration.cpp, line 3193 The problem here was that my data type for the `objectPoints` was just `vector<Vec3f>` and not `vector<vector<Vec3f>>`. In order to save other people the time looking for this, I added explicit examples of the needed data types into the documentation of the function. I had to re-read the current version a couple of times until I can read the needed levels of `vector<>`. Having this example would have really helped me there. |
