Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a LED shadowless light source angle arrangement structure for fruit vegetables visual detection, includes detection room 1, industry camera 2, reflector panel 3, LED light source 4, LED light screen 5, fruit vegetables A, light orbit B, light irradiation region C, and the inside top fixed mounting of detection room 1 has industry camera 2, and there is reflector panel 3 in the inside of detection room 1 through bolt fixed mounting, and fixed mounting has LED light source 4 on the inner wall of detection room 1.

Further, the industrial camera 2 is located the position directly over the reflector 3, and the fruit and vegetable A is placed to the position directly under the reflector 3, and the fruit and vegetable A under the reflector 3 is photographed and detected through the industrial camera 2.

Further, the reflector 3 is arc-shaped, a layer of white paint is sprayed on the inner surface of the reflector 3, the light ray track B emitted by the LED light source 4 is changed through the reflector 3, the light reflected by the arc-shaped reflector 3 has the same incident angle and reflection angle according to the light reflection principle, and the normal line passes through the circle center of the arc.

Further, 4 symmetries of LED light source set up on the inside that detects room 1, and LED light source 4 is located the below position of reflector panel 3, avoids the light direct irradiation that LED light source 4 sent to fruit vegetables A's surface to avoid fruit vegetables A's surface to form the hi-lite facula, thereby can not influence the collection of industry camera 2.

Further, the LED light shading plate 5 is fixedly installed on the surface of the LED light source 4, the light source irradiation angle is adjusted through the arranged LED light shading plate 5, the light divergence area is changed, the light source direct irradiation light and the reflected light cannot directly irradiate the surface of the fruit and vegetable A, and therefore high-brightness spots on the surface of the fruit and vegetable A are eliminated, and a shadowless area is formed.
