Abstract

The technology belongs to the field of image enhancement and specifically relates to an SoPC-based novel infrared image enhancement processing method. The method comprises the following steps: a gray scale mean value Ha, a gray scale maximum value HM and a gray scale minimum value of H(p) are obtained; an upper limit platform threshold value TH is obtained; a lower limit platform threshold value TL is obtained; a double platform histogram correction value HT(p) of an image is obtained; a cumulative histogram FT(p) of the image is obtained.

Description

technical field [0001] The technology belongs to the field of image enhancement, and specifically relates to a novel infrared image enhancement processing method based on SoPC. Background technique [0002] The infrared imaging system absorbs the energy radiation of the target object and converts it into an electrical signal to generate an infrared image, which broadens the scope of human visual cognition. [0003] A thermal imaging camera is an imaging device that uses infrared imaging technology. It takes the infrared focal plane device as the core, and converts the infrared radiation energy emitted by the target scene into a grayscale image visible to the human eye. The infrared radiant energy in the scene is projected onto the infrared focal plane through infrared proficiency, and the detector converts the radiation into a corresponding electrical signal, realizing the conversion from light to electricity, and then processes the electrical signal through the circuit sys...
