I performed OpenCV's chessboard calibration on an Amcrest IP8M-2496EB-40MM PoE IP camera (3840x2160 image, 4.0mm narrower angle lens). The normally barrel shaped distortion is removed with a small loss in FoV, a good compromise. The result is a nice high-resolution image that is distortion free, which I use for weather time-lapse videos.\n\nSee the documentation for details:\n[Camera calibration with square chessboard](https://docs.opencv.org/4.5.1/d4/d94/tutorial_camera_calibration.html)\n\n\u003ccode\u003ecamcalibration.py\u003c/code\u003ehas calibration parameters for the Amcrest IP8M-2496EB-40MM and a simple example of how to undistort.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fidatum%2Fopencv-utilities","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fidatum%2Fopencv-utilities","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fidatum%2Fopencv-utilities/lists"}
