Abstract
本发明提供一种基于机器视觉的电路板生产控制智能质检方法及系统，获取电路板生产流水线上连续采集的电路板原始图像序列，生成电路板表面特征演化图以表示同一电路板单元在不同生产工序下的表面状态变化关系。调用视觉质检模型对特征演化图进行制造缺陷关联分析，得到电路板单元在多个生产工序中的缺陷演化路径包含缺陷形态变化序列和缺陷位置迁移轨迹。基于缺陷演化路径生成质量状态标识，用于指示缺陷产生工序定位和缺陷传播影响范围。根据质量状态标识对生产流水线中的控制参数进行自适应调节处理，得到调节后的生产控制指令并下发至对应生产工序的执行机构。本发明实现了对电路板生产过程的智能监控和质量控制，提高了生产效率和质量稳定性。
