Abstract

The invention discloses an exposure feedback type fluorescent navigation endoscope system and an image processing and self-adjusting method. By reading exposure parameters of a white-light camera in real time, image processing related parameters are calculated, original signals transmitted by a fluorescent camera are adjusted, and processed signals are output to a terminal to be displayed, so output fluorescent images are kept consistent in brightness under different imaging distances.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to an exposure feedback fluorescent navigation endoscope system and an image processing self-adjustment method. Background technique [0002] Fluorescent contrast agents are widely used in intraoperative lymphatic marking, tumor boundary demarcation, angiography and cholangiography, etc. In order to intuitively display the fluorescence position, the current fluorescence navigation image system obtains the white light image and the fluorescence image separately, extracts the fluorescence signal through an algorithm and marks it on the white light image, and obtains a terminal image with a composite effect. At different working distances of the endoscope, the light area irradiated to the target tissue is different, and the excitation optical density of the excitation contrast agent changes, resulting in a change in the intensity of the fluorescence signal source, and the signal detector...
