Machine vision system based on programmable area array light source and application thereof

Abstract

The invention belongs to the technical field of detection equipment, and relates to a machine vision system based on a programmable area array light source and application thereof. The system comprises a box body, the programmable area array light source, a light controller and an industrial personal computer, wherein the programmable area array light source is fixed at the top in the box body, and a platform is arranged at the bottom of the box body and used for placing an object to be detected; the light controller is connected with the industrial personal computer, and the industrial personal computer controls the color, the brightness and the illumination of the programmable area array light source through the light controller; and a camera is arranged in the center of the programmablearea array light source and is controlled by the industrial personal computer. A low-cost color display screen module commonly used in the market is utilized, a local lighting environment with any shape and any color, which meets the requirements of the visual algorithm, is formed, the machine vision system for detecting the large-size workpiece based on the programmable area array light source is convenient to build, low in price, high in adaptability and wide in application range, and mutual interference caused by lighting environment difference of different areas is avoided.

Description

Technical field [0001] The invention belongs to the technical field of detection equipment, relates to a machine light source vision system, in particular to a machine vision system based on a programmable area array light source and its application. Background technique [0002] At present, the machine vision light source system needs to adopt different light sources according to the local characteristic attributes of the object when detecting a certain specific industrial part, so as to achieve the best lighting environment that meets the requirements of the algorithm. However, current industrial visual lighting sources usually have a fixed lighting range and are relatively expensive, and it is difficult to meet specific local lighting conditions when detecting features of larger workpieces. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings of the prior art, and provide a machine vision system for detecting large-scale a...
