Camera Calibrator

Camera Calibrator is a hosted web application for camera calibration, sold as a one-time purchase. The whole workflow runs in the browser: you capture images of a calibration target, upload them, select the camera model, pattern type and input parameters, run the calibration and download the results — without writing any code. Two target types are supported: ChArUco boards, presented as the more robust option for complex environments, and regular checkerboards for straightforward, controlled settings. The output is the camera matrix and the distortion coefficients, exported as JSON and accompanied by ready-to-use Python and C++ example snippets to load the parameters into your own project. To help judge the result, the app provides reprojection-error plots and a 3D view showing the estimated positions of the calibration board relative to the camera. Being a hosted service, it works from any operating system, computer or phone, but it requires an internet connection and uploading your images to the service. The purchase includes lifetime access and future updates.
