Infrared thermal imager of different manufacturers has different image color display, the effect of image color processing is also different. For example, There are 12 kinds of color palettes for Yoseen infrared thermal imaging camera, such as iron red, white hot, black hot, rainbow, etc., the effect of different color palettes is also different.

By receiving the infrared radiation emitted by the object, the infrared thermal imager converts the surface temperature distribution of the object into the visible image of the adult eye, and displays it in different colors. The displayed image represents the infrared radiation distribution of the object, which depends on the spatial distribution of the emissivity and temperature of the object. However, the actual infrared measurement images collected are generally gray images, and the analysis and processing of the measured images are limited by the fact that there are only dozens of gray levels that can be resolved by human eyes. However, human eyes are highly sensitive to color and can distinguish hundreds or even thousands of colors. Therefore, the pseudo-color processing of the measured image can improve the contrast of the image, make the measured image and the background hierarchized, make the target easier to recognize, and meet the higher requirements for display effect.

As shown in the figure above, the white heat palette is used in the left image and the iron red palette is used in the right image. The high temperature and low temperature areas can be clearly and intuitively seen with the iron red palette, and the details are shown more clearly.

Different application industries have different palette choices, some require white heat, some require rainbow, some require high contrast, etc. Therefore, the more selective the palette, the better. There are 12 kinds of color palettes to choose from in The infrared thermal imager. The detail processing of the image is also very good. The unique algorithm of the front end makes the image very clear, and the temperature measurement is fast, accurate and cost-effective.
