Loading Calibration Parameters

This example demonstrates how to load camera calibration parameters required for image preparation.

Before preparing images, you must load the calibration file (.dat file) that contains camera-specific parameters. These parameters are used during image preparation to perform noise replacement.

Example

#include "dpcore/dpcore.h"
#include "jetraw/dp_status.h"
#include <iostream>

int main() {
    // Load calibration parameters from a file
    dp_status status = dpcore_load_parameters("./calibration.dat");

    if (status != dp_success) {
        std::cerr << "Failed to load calibration file: "
                  << dp_status_description(status) << '\n';
        return 1;
    }

    // Calibration parameters are now loaded and ready to use
    // ... rest of your code ...
}

Notes

• The calibration file path can be provided via command-line arguments rather than hardcoding it in your program.

• If you don’t have a calibration file, you can find example files at: https://github.com/jetraw/pydpcore/blob/master/pco_3a2dd3a.dat

• You can also use dpcore_init() to load parameters from default locations. See dpcore_init() for details.
