Abstract

The invention provides a multi-spectrum modulation imaging device based on a multi-wavelength LED light source. A lighting lens is installed on one side of the main body shell, a projection lens is installed on the side of the lighting lens, and an LED light tool is installed on the side of the main body close to the lighting lens above the lighting lens. A color filter device is installed at the corresponding position of the lighting lens, a large straightening device is installed inside the main body shell at the position facing the lighting lens and the color filter device, and a DMD is installed inside the main body shell above the large straightening device. A reflective sheet corresponding to the DMD is installed on one side of the straightener, and a small straightener is installed between the luminescent sheet and the DMD. By turning on the LED light fixture, the object is projected with white light for basic imaging, and then matched with the colored light irradiation, so that the external equipment can collect Analyze and compare the spectral difference, so as to complement the corresponding color and make the imaging color fuller, so as to ensure the authenticity of the image.

Description

technical field [0001] The invention relates to the technical field of LED light source imaging, in particular to a multi-spectrum modulation imaging device based on multi-wavelength LED light sources. Background technique [0002] A multispectral image is one that contains many bands, sometimes as few as 3 (color images are an example) but sometimes many more, even hundreds. Each band is a grayscale image representing the brightness of the scene according to the sensitivity of the sensor used to generate the band. [0003] It is more common to use LED light for multi-spectral imaging, but the light wave range of LED light is relatively single, resulting in poor imaging saturation and color distortion. [0004] Therefore, it is necessary to provide a new multi-spectral modulation imaging device based on multi-wavelength LED light sources to solve the above technical problems. Contents of the invention [0005] In order to solve the above technical problems, the present i...
