Embodiment

[0041] Such as figure 1 As shown, the present invention proposes a method for processing images obtained by infrared sensors, including four processing parts: detail enhancement, dimming, denoising, and false color, wherein detail enhancement refers to the enhancement of detail information in the image , so that the image details are more prominent and the edges are sharper, and the dimming is to nonlinearly map the original data and compress its size, and then filter the noise information in the image through denoising to make the image look cleaner, and finally use Pseudo-color performs color mapping on the processed grayscale image, converts it into a color image, and finally converts the original image into a color image that can directly reflect the temperature state distribution. Preferably, the platform histogram algorithm is used in the dimming processing, and in this embodiment, the input data dynamic range of the original image img0 is 16 bits, and the output data af...

Abstract

The invention provides a method for processing images obtained by an infrared sensor, including four processing parts: detail enhancement, dimming, denoising, and false color. Then the original data is nonlinearly mapped and its size is compressed, then the noise information in the image is filtered by denoising, and finally the processed grayscale image is color-mapped by using pseudo-color, and converted into a color image; the present invention uses New methods such as unilateral grayscale filtering, and denoising, new iron red pseudo-color, etc., so as to smooth the grayscale of the edge pixels of the image, obtain an image with fewer faults, and not lose too much detail while denoising , to maintain the integrity of the image, especially to protect the edge of the image, to obtain a higher restoration effect, and to enable the observer to have a more distinct color distinction when observing a high-temperature object, so that it is easier to precisely locate the heat source .

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for processing images collected by an infrared sensor. Background technique [0002] The infrared imaging electronic component is an important part of the thermal imaging system. It is responsible for giving full play to the performance of the infrared focal plane detector and converting the electrical signal output by the infrared focal plane detector into a video signal or a signal in a format specified by the system. Features. Infrared imaging electronics components include hardware systems and image processing algorithms. Since the current hardware system platform is already perfect, infrared image processing technology has become an important research content of imaging electronics components. [0003] Infrared image processing technology needs to be carried out according to the specific characteristics of infrared images. Limited by the manufacturing pro...
