Embodiment Construction

[0012] The following will be described in detail in conjunction with the embodiments of the present invention with reference to the accompanying drawings.

[0013] FIG. 1 is a schematic structural diagram of a non-interference color acquisition device of a straight machine vision system. The end face of the detection port of the straight color acquisition device is perpendicular to the axis of the photodetector, lens, diffuse condenser and light source group for illumination, and its shell is a cylindrical shell. Its structure firstly packs the diffuse condenser lens 4 into the cylindrical shell 5 from the front end of the cylindrical shell 5, and then packs the light source drive circuit board 3 for illumination with the light source 2 for illumination into the cylindrical shell 5. Then, the lens 8 is installed in the lens holder 7 and fixed with the lens pressure ring 6 . Then the photodetector driving circuit board 11 embedded with the photodetector 10 is fixed on the lens...

Abstract

The invention is a non-interference color collected device of machine vision system, including a casing, a lighting source for, a diffusion condenser, a lens, a photoelectric detector and a driving circuit of light source and photoelectric detector, etc. The casing is a long sleeve with an opening on the front end, a rear cover on the rear end, or a corner-shaped sleeve. The device of the invention is superior in reducing the demand for environment in which the color information can be collected under any situation with simple structure and portability, which can be applied in the color information collection of skin, hypertrophyic scars, presswork and textiles, etc.

Description

【Technical field】 [0001] The invention relates to the field of photoelectric detection of colors, in particular to a non-interference color acquisition device of a machine vision system. 【Background technique】 [0002] Color is an important characteristic parameter of an object. Objects that cannot be detected by differences in gray levels can often be detected by differences in color information. Therefore, color-based object detection has received extensive attention from researchers. For example, the detection of the color quality of printed matter, the judgment of the ripeness of plant fruits and the removal of foreign matter, and even the current quantitative determination of skin color and the judgment of the treatment effect of hypertrophic scars all involve color detection. [0003] The detection of the target color is still mainly done manually at present. However, human vision is subjective, and there will be different degrees of color vision differences among ind...
