机器视觉的金手指外观缺陷检测
发表时间:2018-11-17

未耒智能(深圳)有限公司对金手指外观缺陷的视觉检测:

FPC产业的迅猛发展,用户对自动化检测设备的个性化需求,形成了FPC产业对新技术装备、新工艺的研发驱动力。针对FPC外观检测人工检测生产成本高,检测生产效率低,大规模生产检测过程会产生大量的漏检、误判,不能满足客户生产需求的问题。设计并研制检测速度快、准确率高、稳定的全自动金手指外观精密检测设备,实现机器换人、降低生产成本、缩短生产周期、提高生产效率和产品质量。

金手指缺陷图像检测主要包括图像彩转灰、图像掩模、边缘提取、二值化等步骤。以多铜、少铜、污渍的检测为例进行缺陷检测,软件处理主要包括:图像采集、图像预处理、缺陷割,形态学处理和缺陷分析。
