The present invention provides a cloud edge height matching method and system based on thermal infrared data. The method comprises a step of obtaining the visible light cloud detection data and the thermal infrared cloud height data in a same time area, a step of obtaining a target image according to the visible light cloud detection data, a step of obtaining a background image according to the thermal infrared cloud height data, a step of selecting one pixel in the target image as a target point, carrying out Euclidean distance transform on the pixel in the background image according to the target point, and obtaining Euclidean distance transform data, a step of obtaining the height value of the target point through a preset search algorithm according to the Euclidean distance transform data, and matching the target point. According to the method and the system, the matching of low-resolution thermal infrared cloud height data to the corresponding high-resolution visible light cloud detection data can be rea
