Problems solved by technology

[0005] The present invention is aimed at the problem that the current fusion method is easy to cause color distortion of the fusion image, and proposes a method for fusion and enhancement of infrared and visible light pseudo-color images. The method is to obtain background information, Target information and cold target information have three different regional characteristics, retain the feature information and perform pseudo-color fusion on infrared and visible light images in the YUV color space, obtain the pseudo-color fusion image and then use the given color reference image to process it Color transfer and color enhancement processing to get the final fusion image

Embodiment Construction

[0037] The hardware structure of the embedded system based on image fusion is as follows: figure 1 shown. Its specific configuration is as follows: Two imaging sensors are used, one is AVT industrial CCD camera F-032B / C, and the other is Infrared Solutions can provide a thermal imager based on uncooled bolometer technology: IR- 160-type imager, which can output 160×120 pixel NTSC or PAL video output signal; the sensor type selection switch and DSP image fusion chip both adopt TI’s TMS320C6000; the A / D multi-channel acquisition chip adopts 24-bit A / D conversion Device CS5381; ARM chip adopts ARM940T produced by ARM Company. Software structure such as figure 2As shown, by pre-segmenting the infrared image, three different regional features of background information, target information and cold target information are obtained, and the feature information is preserved and the infrared and visible light images are fused in false color in the YUV color space After obtaining the ...

Abstract

The invention relates to an infrared and visual pseudo-color image fusion and enhancement method. The method comprises the following steps: performing advanced partition treatment on infrared images to acquire three different area characteristics of background information, target information and cold target information, preserving characteristic information, performing pseudo-color fusion on the infrared and visual images under a color space of YUV to acquire pseudo-color fusion images, and then performing color transfer and color enhancement treatment on the pseudo-color fusion images by using a given color reference image to acquire final fusion images. The method can cause the final fusion images to have more area characteristic information, and furthest promote the color quality of the fused images at the same time of ensuring the instantaneity of a system.

Description

technical field [0001] The invention relates to an information processing method, in particular to an infrared and visible light pseudo-color image fusion and enhancement method. Background technique [0002] Generally speaking, the image fusion method is currently divided into two branches, one is the fusion method for grayscale images, and its representative is the image fusion method based on multi-resolution; the other is the image fusion method for color The method mainly performs fusion processing on images to be fused with color information, and also includes a pseudo-color image fusion method that performs color compensation on grayscale images. Generally speaking, the main purpose of these two methods is to improve the accuracy of the position evaluation of the fused image, so as to achieve a higher recognition rate whether it is human eye observation or machine recognition. [0003] The fusion method for grayscale images, that is, the multi-resolution image fusion...
