Abstract

The invention discloses an infrared image pseudo color processing method based on a YUV color space. The infrared image pseudo color processing method based on the YUC color space comprises steps of using a YUV format gray-scale image obtained from an infrared thermal imaging system, using a gauss low pass filter to perform pretreatment on the YUV format gray-scale image, extracting a value of a Ychannel of the YUV format gray-scale image which is the gray value, establishing a mapping model I between the gray scale value Y and an RGB color space through a gray scale and color conversion method, establishing a mapping model II between the YUV color space and the RGB color space according to an NTSC system standard and establishing a pseudo color processing model III based on the YUV colorspace according to the model I and the model II . The infrared image pseudo color processing method based on the YUV color space can directly convert the gray scale image to the pseudo color image through the established model III. The infrared image pseudo color processing method based on the YUV color space can save conversion time of the color space under a condition that quality and a contrast ratio of the image are constant with a traditional pseudo color processing effect based on the RGB color space and can dramatically improve processing efficiency and instantaneity.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an infrared image pseudo-color processing method based on a YUV color space. Background technique [0002] Infrared imaging technology is a radiation information detection technology. Any object with a temperature higher than absolute zero is constantly radiating energy outward. The infrared image reflects the spatial distribution of the infrared radiation of the measured target and the background, and contains a large number of details of the target that is the background. information. A special electronic device can be used to convert the temperature distribution on the surface of the object into an image visible to the human eye, and display it in different colors. The displayed image represents the infrared radiation distribution of the scene, which depends on the spatial distribution of the emissivity and temperature of the scene. The infrared thermal imaging temperature me...
