基于虚拟仪器的六面视觉影像记录系统设计与实现

Design and Implementation of Hexahedral Visual Image Recording System Based on Virtual Instruments

为解决产品装配过程影像数据信息管理与质量追溯问题,提出一种基于虚拟仪器的外观六面视觉影像记录系统,采用图像处理技术对产品视觉影像进行数据采集与信息绑定。首先,设计一种四方位影像检测系统,通过旋转180°实现反面外观影像采集。其次,开发一套集实用性和应用性于一体的视觉平台实现外观六面影像实时采集。最后,采用LabVIEW生产者/消费者设计模式,通过2个循环来完成图像数据采集和视觉系统控制,利用队列方式来连接2个循环,实现各个循环的有效组合。经试验验证,设计的系统稳定性好、效率高,1个产品六面视觉影像记录时间仅为12 s,具有较好的实用性。

In order to solve the problem of image data information management and quality traceability in product assembly process,a hexahedral visual image recording system based on virtual instrument was proposed.Image processing technology was used for data collection and information binding of product visual images.Firstly,a quadrilateral image detection system was designed,which can acquire the image of the opposite side by rotating 180°.Secondly,a set of practical and applied visual platform was developed to realize the real-time acquisition of hexahedral image.Finally,a LabVIEW producer/consumer design mode was adopted,and the image data acquisition and visual system control were respectively performed in two cycles,and the two cycles were connected by means of a queue to realize an effective combination of each cycle.It is verified by experiments that the designed system has good stability and high efficiency,and the recording time of hexahedral visual images of a product is only 12 seconds,which has good practicability.
