Abstract

The invention provides a multi-spectral camera shooting and projecting apparatus and a multi-spectral camera shooting and projecting method. The multi-spectral camera shooting and projecting apparatus comprises a camera shooting assembly, a computing processor assembly and a projecting assembly, wherein the camera shooting assembly collects and outputs image information of light within first-class wavelength range and second-class wavelength range at a preset area; the computing processor assembly selects a color blending scheme comprising the color and intensity of a projection image as well as the color and intensity of the projection background according to the reflection spectrum characteristics of the preset area obtained from the image information of the light within the first-class wavelength range, and synthesizing the image information of the light within the first-class wavelength range and the second-class wavelength range, the projection relevant information and the projection background into the projection image according to the color blending scheme; the projecting assembly projects the synthesized projection image to the preset area in the form of the light within the first-class wavelength range at the projecting stage. According to the apparatus and the method provided by the invention, color blending selection with certain self adaptation or optimization is carried out on the projection image and the projection background, so that the contrast ratio and identifiability of the projection image are enhanced, and a reliable basis is provided for various operations based on the projection image.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a multispectral imaging and projection device and method for improving the color contrast and recognizability of projected images. Background technique [0002] The structures and tissues inside the human body cannot be directly seen by the human eye. It is difficult to accurately find and locate the subcutaneous internal structure and tissue only relying on the external contour of the human body and the knowledge of human anatomy. [0003] Human blood vessels are hidden under the epidermis and are often blocked by subcutaneous fat or even bones. In a visible light environment, the visible light image signal reflected from the human subcutaneous tissue is very weak and mixed with various noises and phantoms, and is even completely invisible to the human eye. . Although before puncture, doctors often ask patients to clench their fists or pat the skin at the p...
