AI Technical Summary
Existing technologies struggle to quickly generate light intensity distributions that conform to IES standards through image analysis, and existing solutions cannot achieve a collaborative technical path of image mapping, accurate brightness calculation, and physical restoration of light intensity, resulting in high dependence on optical equipment and low testing efficiency.
By using the mapping relationship between planar pixel coordinates and spherical angles, the pixel coordinates of each pixel in the target image are converted into spatial angular coordinates. The initial brightness is calculated and corrected, and the light intensity is calibrated by combining the measured calibration factor to generate the light intensity distribution result.
It enables the rapid generation of light intensity distributions that conform to IES standards while ensuring data accuracy, reducing reliance on professional optical equipment and improving testing efficiency.
