The invention provides a multispectral modulation imaging device based on a multi-wavelength LED light source. A lighting lens is mounted at one side of a main body shell; a projection lens is installed at the side, located on the lighting lens, of the main body shell. An LED optical tool is installed at the side, close to the lighting lens, of the main body shell and located above the lighting lens. A color filter device is arranged at a position, corresponding to the lighting lens, in the main body shell; a large straightener is arranged at the position, right opposite to the lighting lens and the color filter device, in the main body shell; a DMD is arranged over the large straightener in the main body shell; a reflector corresponding to the DMD is mounted at one side of the large straightener; a small collimator is installed between a light-emitting piece and the DMD, the LED light tool is started to project white light to an object, basic imaging is carried out, colored light irradiation is matched, external equipment is made to carry out collection and analysis, spectral difference comparison is carried out, corresponding colors can be supplemented conveniently, imaging colors are made to be full, and therefore the authenticity of images is guaranteed.
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...
