Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0028] Such as figure 2 As shown, the specific embodiment of the present invention is: provide a kind of real-time suppression method of thermal window effect of infrared image, comprise the steps:

[0029] Acquiring cold state image and temperature information: when the infrared imaging device is cold, obtain the image data Image_Data1 and temperature Temp1 of the infrared detector of the infrared imaging device facing the uniform radiation scene.

[0030] The specific implementation process is: when the infrared imaging device is cold, the image data Image_Data1 of the infrared detector of the infrared imaging device facing the uniform radiation scene is obtained, and the temperature Temp1 at this time is obtained at the same time, and the image data Image_Data1 and temperature Temp1 are stored.

[0031] Acquiring thermal equilibrium state ima...

Abstract

The invention relates to an infrared image hot window effect real-time isuppression method and system. The method comprises the steps: obtaining an image hot window effect compensation value [delta] B according to the starting temperature Tstart and real-time temperature Treal of an infrared device, and a stored image data difference value [delta] ImageData and a temperature difference value [delta] Temp; enabling the calculated image thermal window effect compensation value delta B to act on the infrared image data for image compensation. The thermal window effect in the infrared image imaging process is solved through a simple method, and the quality of the infrared image is greatly improved.

Description

technical field [0001] The invention relates to an infrared image correction method and system, in particular to a real-time suppression method and system for thermal window effects of infrared images. Background technique [0002] Infrared thermal imaging technology has been widely used in various fields such as military, medical, security, agriculture, forestry, and industry. However, due to factors such as the power consumption of infrared thermal imaging equipment itself, heat dissipation of structural parts, or defects in optical systems, etc. After a period of time, there will be obvious non-uniformity phenomenon in the edge and center area of ​​the image - "hot window" effect. The thermal window effect will significantly reduce the image quality, affect the user experience, and even directly cause some application scenarios to fail to work normally. [0003] There are many reasons for the "hot window" effect of infrared images, such as high power consumption, serious...
