kandi X-RAY | ccalib Summary

ccalib is a C library typically used in Video, Camera applications. ccalib has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

ccalib is a simple and easy to use GUI for (currently) monocular intrinsic camera calibration. It let's you stream directly from your webcam (or any uvc / v4l2 device) without the need to have a separate app or ROS-node to publish images first (the camera needs to be mountable as /dev/video). The app provides intuitive way to take snapshots for calibration in an automatic fashion as well as offers the possibility to manually take additional snapshots for refinement. It shows camera parameter coverage, as well as the re-projection error for every single frame that has been taken. Results can easily be exported in YAML format.

This has nothing to do with make per se. The problem is that your compiler invocation is wrong for the include statement you have.

You can debug this yourself: first, see the command make invoked:

OpenCV for Android self-compiled library 10x larger than official built

Asked 2021-Mar-23 at 12:28

I try to build the OpenCV 4.5.1 SDK for Android because I need the SDK with contrib modules and the official release [1] only has the standard modules. But the libraries I build are almost 10x larger, for example: libopencv_core.a ==> 47.6 MB self compiled, 5.3 MB from the official repository (both for arm64-v8a)

Here is my cmake command, followed by ninja for compilation.

For points 1 and 2, you can test by passing the second argument to VideoCapture(filename[, apiPreference]). Since you have OpenCV built with ffmpeg and v4l2. I would try the following options cv::CAP_FFMPEG, and CAP_V4L2. For point 4, make sure your webcam is 1080p.
