摘　　要：为改善人工检测灯泡头焊丝外漏存在的诸多弊端,开发一套基于DSP+ARM双核嵌入式DM6446开发板设备的灯泡头焊丝自动检测系统。设计实现基于V4L2驱动接口的视频采集线程、基于codec engine构架的视频处理线程和基于FBdev驱动接口的视频显示线程,开发运行在DSP侧的灯泡头焊丝检测算法。整个装置有效地对有焊丝外漏的灯泡进行识别,实现了高准确率的灯泡产品合格检测,替代了人工检测。To overcome the shortcomings of manual inspection of bulb head,a light bulb wire detection system by using embedded board equipment DM6446 which based on DSP ＋ ARM dual-core processor was presented.Video capture thread based on V4L2 drive interface,video processing thread based on codec engine framework and video display thread based on FBdev drive interface were designed and implemented.Moreover a wire detection algorithm of bulb head which ran in the DSP side was developed.The entire device can effectively identify wire leakage of the bulb and achieves a high accuracy rate of qualified products detection,which is superior to manual inspection.
