Problems solved by technology

[0002] At present, the light sources used in pearl image acquisition are mainly planar light sources or hemispherical light sources, which can only emit uniform light on one surface of spherical objects, and cannot solve the problems of shadows, spots and highlights on the surface of objects due to uneven illumination. Shadows, large light spots or highlights will cover the images collected by real-time inspection, so industrial cameras cannot collect real and near-comprehensive pearl surface images through existing light sources

Embodiment Construction

[0024] As shown in the sphere light source device, the outer sphere 1 and the translucent inner sphere 2 that make up the sphere have the same center, the translucent inner sphere is made of acrylic material, and the outer wall of the outer sphere is covered with a layer of reflective material. Both the inner and outer spheres are formed by butt joints of two hemispheres. The two hemispheres of the inner sphere 2 are respectively positioned on the two hemispheres of the outer sphere 1. Camera shooting holes 3 are distributed on the two hemispheres of the inner and outer spheres. The inner sphere The camera shooting hole on the outer ball communicates with the camera shooting hole on the outer ball and is at the same axis position, and the camera shooting hole on the outer ball is slightly larger than the camera shooting hole on the inner ball. A plurality of luminous bodies 8 are evenly distributed on the outer sphere (the luminous bodies are light-emitting diodes, such as im...

Abstract

Disclosed is a light source device applied to collecting images of spherical objects which easily generate specular reflection such as on pearl and the like. The existing light source only can emit uniform light to one surface of a spherical object, but can not resolve problems of shadow, facula, specular reflection and the like caused by uneven illumination on the surface of the object. The light source device comprises a sphere, which is characterized in that the sphere comprises an outer sphere and a transparent inner sphere, the outer sphere and the inner sphere have the same sphere center, same camera shooting holes are arranged on the inner sphere and the outer sphere, the camera shooting hole on the inner sphere is communicated with the camera shooting hole on the outer sphere, the outer sphere is equipped with a plurality of luminous bodies which emit light inwards, and the upper end and the lower end of the sphere is equipped with through holes. The light source device resolves problems that in the image collecting process, the surface of the pearl generates shadow, facula, specular reflection and the like caused by uneven lighting.

Description

technical field [0001] The invention relates to a light source, in particular to a light source device used in image collection of pearls and other spherical objects that are prone to high light. Background technique [0002] At present, the light sources used in pearl image acquisition are mainly planar light sources or hemispherical light sources, which can only emit uniform light on one surface of a spherical object, and cannot solve the problems of shadows, light spots and highlights caused by uneven illumination on the surface of the object. Shadows, large light spots or highlights will cover the images collected by real-time inspection, so industrial cameras cannot collect real and near-comprehensive pearl surface images through existing light sources. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a spherical light source device that emits light in...
