Embodiment

[0041] like 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 after...

Abstract

The invention provides a method for processing an image obtained by an infrared sensor. The method comprises four processing parts of detail enhancement, dimming, denoising and pseudo color. Detail enhancement refers to enhancement of detail information in the image. Dimming refers to non-linear mapping of original data and compression of the size of the original data, noise information in the image is filtered through denoising, and finally color mapping is performed on the processed grayscale image by using pseudo-color to convert the grayscale image into a color image. According to the invention, new methods such as single-side gray scale filtering, denoising, new iron red pseudo-color and the like are used. Therefore, the gray scale of the edge pixel point of the image is smoothed. Theimage with fewer faults is obtained, excessive details are not lost while denoising is carried out. The integrity of the image is maintained, especially the edge of the image is protected. A relatively high restoration effect is obtained. An observer can have more distinct color level distinguishing when observing a high-temperature object, so that the heat source can be more easily and accurately positioned.

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. Function. 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...
