基于LabVIEW的食品包装喷码视觉检测方法

Visual inspection method for food packaging character printing based on LabVIEW

目前食品包装的喷码检测大多还是靠人工方式进行,在一定程度上会造成漏检误检现象,影响食品安全。针对该问题,提出一种食品包装喷码的视觉检测方法,利用LabVIEW为开发平台,开发喷码视觉检测系统,并详细介绍图像获取、预处理、定位、识别等关键步骤。经样本测试表明,该方法的识别准确率高,可以代替人工实现食品包装的自动化分拣。

At present,most code printings of food packaging are still inspected artificially.It will cause miss or error inspection in a certain extent,so that the food security will be impacted.A visual inspection method for food package code printing is put forward to solve this problem.Using LabVIEW as the development platform,a visual inspection system of code printing was developed.The key steps of image acquisition,preprocessing,orientation and recognition are detailed introduced.Finally,tests were performed on the samples.The results showed that the recognition accuracy of this method was high,thus the automatic sorting of food packaging could be achieved.
