AI Technical Summary

Technical Problem

[0006]尽管上述现有技术在一定程度上满足了工业视觉检测的基本需求，但面对日益复杂多样的工业检测场景，仍存在以下突出的技术问题：不同的被检测物体具有各异的材质、形状和表面特性，例如金属材质表面反光强烈，塑料材质对光线吸收和散射情况不同，曲面物体的光线反射规律与平面物体也大相径庭

Benefits of technology

[0037] First, this invention significantly improves the scene adaptability and hardware versatility of the light source system through a pixel-level light source architecture with independent control of each individual LED. The illumination mode of traditional standardized light sources is determined by their fixed physical structure and cannot be changed once manufactured, making them insufficiently applicable to complex and diverse detection scenarios. This invention employs a hemispherical structure with layered RGB LED arrays on its inner wall. The color of each LED can be individually controlled by a control circuit board, and the light field distribution can be reconstructed through software configuration. This allows the same hardware to simulate various traditional light source illumination forms, such as dome light sources, high-angle ring light sources, and low-angle ring light sources. As a result, the light source hardware can be standardized and universally produced, and adaptation to detection scenarios is accomplished through software configuration, greatly reducing the hardware replacement costs caused by changes in detection requirements and solving the technical problem of insufficient flexibility in existing light source systems.

Abstract

The application discloses a kind of single lamp bead independent control's machine vision intelligent light source system, including hemispherical light source and host computer.Light source inner wall is arranged multiple RGB lamp beads in layers, control circuit board independently controls each lamp bead color, and all lamp bead color values constitute lighting configuration.Host computer is communicated with light source and industrial camera, and built-in image feature calculation module and illumination optimization module.Host computer drives camera to shoot the image of product to be measured, calculates image characteristic value, iteratively optimizes new lighting configuration by multi-objective optimization algorithm (such as genetic algorithm) output to maximize or minimize characteristic value, and sends to light source and updates lighting.By controlling the brightness of different layered lamp beads and color combination, the host computer supports manual configuration and automatic optimization, and the optimal configuration can be stored in the light source. After being separated from the host computer, it can be called and switched by external I / O or communication instructions. The application realizes one machine with multiple uses and intelligent optimization of lighting, and improves the scene adaptability and debugging efficiency of machine vision detection.
