Material detection device and color sorter

Abstract

The invention provides a material detection device and a color sorter. The device comprises a front-view light source, a rear-view light source, a front-view camera, a rear-view camera and a processing device, wherein the front-view light source and the rear-view light source are symmetrically distributed on the two sides of a material and are sequentially and alternately turned on or off; the front-view camera is arranged on one side of the front-view light source, the rear-view camera is arranged on one side of the rear-view light source, and the front-view camera and the rear-view camera are area-array cameras and are used for synchronously shooting the material; and the processing device is connected with the front-view camera and the rear-view camera and is used for identifying the material according to images obtained by the front-view camera and the rear-view camera. According to the material detection device and the color sorter, a two-side alternate illumination mode is adopted, so that the adverse effect of the light source on one side on signal acquisition of the camera on the other side can be effectively eliminated in the material detection, identification and sorting processes; and meanwhile, the problem that the two sides of the material cannot be identified due to single-side illumination can be solved, the identification range of the material cannot be influenced, and therefore the material detection, identification and sorting effects can be improved.

Description

technical field [0001] The invention relates to the technical field of color sorters, in particular to a material detection device and a color sorter. Background technique [0002] At present, for the material sorting device arranged with front and rear view mirrors, there are mainly two lighting methods, one is lighting with a single-side light source, and the other is lighting with a double-side light source. [0003] When a single-side light source is used for lighting, the identification of the material will be incomplete, the identification range of the material will be lost, and the recognition effect will be greatly reduced. Therefore, in practical applications, the way of lighting with a single-side light source is generally not considered. [0004] When using a double-sided light source for lighting, the light source on one side of the material will affect the signal collected by the camera on the other side, especially a bright ring will appear on the edge of the s...

Problems solved by technology

[0006] Therefore, an object of the present invention is to propose a material detection device, which adopts double-sided alternate lighting, and can effectively eliminate the impact of the light source on one side on the signal acquisition of the camera on the other side during material detection, identification, and sorting. At the same time, it can solve the problem that one-sided lighting cannot identify both sides of the material, and will not affect the identification range of the material, thereby improving the effect of material detection, identification and sorting
