摘　　要：基于DM642和CPLD架构实现农产品图像的采集与处理,并利用Canny算子检测农产品图像边缘信息。针对农产品种类丰富、外形多样、边缘信息复杂且图像在采集过程中容易受到外界因素影响的特点,采用一种新的调试技术,将Matlab和DSP两者结合起来,充分利用两者特长,在线调节Canny算子阈值,简化系统开发的分析、调试和验证过程,并使系统具有更强的通用性,满足不同农产品边缘检测需要。This paper realizes agricultural image acquisition and processing based on DM642 and CPLD,and detectes the edge information with Canny operator.For the variety of agricultural products,the information of their edges is very complex and their images are also sensitive to external factors in acquisition process.In view of the above problems,this article adopts a new debug technology,combining Matlab and DSP,to adjust the Canny operator threshold online.Experimental results show that the method can simplify the process of system analysis,debug and validation,and meet the needs of different kinds of agricultural products edge detection.
