Apparatus, system, and control method for measuring LED panel

A light-emitting diode (LED) panel measuring apparatus comprising:

• an input interface;
• a display;
• at least one memory storing a trained artificial intelligence model;
• and
• at least one processor configured to:
• control the input interface to receive an image of an LED panel displaying a preset color,
• classify, based on the received image of the LED panel, each pixel of the LED panel into pixel regions comprising different sizes, wherein the size of each pixel region corresponds to a predetermined threshold brightness value,
• obtain a tristimulus value of each pixel of the LED panel based on the data of the classified pixel regions and the trained artificial intelligence model, and
• obtain a luminance and a chromaticity of each pixel of the LED panel based on the obtained tristimulus value, and
• display the obtained luminance and the obtained chromaticity of each pixel on the display.

A light-emitting diode (LED) panel measuring system comprising:

• a camera configured to capture an image of an LED panel while the LED panel displays a preset color;
• and
• an LED panel measuring apparatus comprising:
• at least one memory storing at least one instruction;
• and at least one processor configured to execute the at least one instruction to:
• receive input of the captured image of the LED panel,
• classify, based on the captured image of the LED panel, each pixel of the LED panel into pixel regions having different sizes, wherein the size of each pixel region corresponds to a predetermined threshold brightness value,
• obtain a tristimulus value of each pixel of the LED panel based on the data of the classified pixel regions and a trained artificial intelligence model,
• obtain a luminance and a chromaticity of each pixel of the LED panel based on the obtained tristimulus value, and
• display, on a display, the obtained luminance and the obtained chromaticity of each pixel.
