摘 要：
为了保证啤酒瓶底检测的硬实时性,避免检测超时和玻璃瓶漏检现象,提高在线检测的速度,设计了一种基于DSP和CPLD图像处理器的瓶底检测算法和检测装置。采用视频模数转换器件实现相机拍摄到图像的模数转换,用DSP图像处理器代替通用工控机来做图像处理,结合时间确定的图像处理算法来保证检测时间的稳定性,用CPLD和图像内存相连,位于模数转换器和DSP之间,读取图像模数转换结果并存储到内存中,供DSP进行处理。整个图像的获取和处理过程都在电路板上完成,解决了通用工控机和图像处理平台的分时特性而带来的超时和漏检问题。

摘 要：
In order to ensure hard real-time detection of bottle of beer, to avoid detection timeout and undetected phenomenon, to improve the speed of online testing, this paper designed a bottom detection algorithm and detection devices with an image processor based on DSP and CPLD. ADC pieces realized from video cameras to image analog digital conversion, DSP image processor, instead of general industrial machine to do the image processing, combined with image processing algorithms to determine the time to ensure the stability of the detection time, and an image memory with CPLD connected, located between ADC and DSP, analogized the digital conversion result to read image and stored in memory for DSP processing. The entire image acquisition and processing procedures were completed on the circuit board to solve a common IPC and image processing platform timeshare properties brought out and missed the problem.
