Abstract

The invention discloses a lighting device, a machine vision device and a lighting adjusting method. The lighting device comprises line light sources and reflection modules; distances between the linelight sources and a target lighting area are preset distances, included angles between the optical-axis light rays in the width directions of the line light sources and the target lighting area are preset included angles, and the preset distances and the preset included angles are arranged to allowing lighting light intensity perpendicular to the length directions of the line light sources in thetarget lighting area to be even; the reflection modules are arranged at the ends in the length directions of the line light sources, and are arranged to be emergent light for reflecting the line lightsources so that the lighting light intensity in the length directions along the line light sources in the target lighting area can be even. According to the lighting device, the machine vision deviceand the lighting adjusting method in the technical scheme, large-area even lighting can be achieved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an illumination device, machine vision equipment and an illumination adjustment method. Background technique [0002] With the gradual development of industrial automation, artificial intelligence and other technologies, machine vision inspection is becoming more and more important. Correspondingly, the role of uniform lighting in inspection is becoming more and more critical. In machine vision equipment, the imaging device collects the imaging image of the measured object under the illumination of the lighting device, wherein the quality of illumination will directly affect the imaging quality, and then affect the detection accuracy of the machine vision equipment. When detecting small-sized objects, you can use a coaxial light source or a uniform point light source to achieve uniform illumination; however, for large-sized objects, neither the coaxial light source nor the unifo...
