RaspiCalib | Camera calibration app from an OpenCV tutorial

RaspiCalib is a C library typically used in Internet of Things (IoT), OpenCV, Raspberry Pi applications. RaspiCalib has no bugs, it has no vulnerabilities and it has low support. However RaspiCalib has a Non-SPDX License. You can download it from GitHub.

RapiCalib is a camera calibration app from an OpenCV tutorial modified to work directly with the Raspberry Pi camera. A modified RaspiVid application is used to provide the image data (in a way similar to the RaspiCV project). The original RaspiVid.c is modified (see d019d18) to pass image and motion vector buffers to callbacks defined in cv.h. File cv.cpp implements these callbacks and provides the latest captured frame to class RaspiVideoCapture. The camera_calibration code and the XML configuration file come from the OpenCV library. The original camera_calibration.cpp is modified (see e2bbc46) to support the Raspberry Pi camera. The exact camera configuration (parametrs passed to the RaspiVid) is in cv.cpp (function process_thread). Currently the configuraton is limited to grayscale format. This can be easily modified (see function cv_init()).
