Problems solved by technology

[0005] The purpose of the present invention is to provide a multi-spectral nasal endoscope real-time image enhancement method and endoscope imaging system, aiming to solve the problem that the image algorithm of the existing NBI technology only involves the recombination of RGB channels, and the effect is only deep and shallow blood vessels Simple separation does not achieve the goal of fully highlighting the mucosal blood vessels

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0037] Such as figure 1 Shown, a kind of multispectral nasal cavity endoscope real-time image enhancement method specifically comprises the following steps:

[0038] Step S100: Collect the image ImageSrc in real time in the nasal cavity (such as image 3 shown);

[0039] Step S200: Decompose the ImageSrc of the original image into grayscale images of three channels of red, green and blue according to the RGB model of the color image, corresponding to ImageSrcR, ImageSrcG, and ImageSrcB respectively (wherein Figure 4 is the grayscale image of the blue channel ImageSrcB);

[0040] Step S300: Perform spatial low-pass filtering on the blue channel image ImageSrcB to obtain a blurred image ImageBlurB representing the low-frequency compone...

Abstract

The invention discloses a multi-spectrum nasal cavity endoscope real-time image enhancement method and an endoscope imaging system. Bluetooth channel information is used for enhancing the effective information of an image on the basis of airspace filtering, ineffective information is weakened so as to intensify a tumor lesion phenomenon, the endoscope diagnosis accuracy of precancerous lesions and early tumors can be subjected to leap improvement, and missed diagnosis is avoided. Meanwhile, on a premise that a processing effect is not affected, the image is subjected to multi-scale airspace filtering so as to achieve an effect on low-time-delay output and real-time operation.

Description

technical field [0001] The invention relates to an image enhancement method, in particular to a real-time image enhancement method of a multi-spectral nasal cavity endoscope and an endoscope imaging system. Background technique [0002] The incidence of nasopharyngeal carcinoma is relatively high in China, especially the high incidence of malignant tumors in southern my country. The incidence of nasopharyngeal carcinoma is increasing year by year, which seriously endangers people's health. Local hospitals hope that early screening and examination can be used to detect nasopharyngeal cancer patients at an early stage, realize early diagnosis and early treatment, and improve the possibility of recovery. [0003] Narrow Band Imaging (NBI) technology of Olympus is an emerging endoscopic technology. Narrowband imaging, diagnosis of related diseases. Because the hemoglobin in the blood has a strong absorption of blue and green light, the contrast between mucosal blood vessels an...
