利用STM32F407高性能、低成本的特点，结合嵌入式机器视觉技术，设计了一种枣嵌入式机器视觉分级系统。首先通过摄像机获取新鲜枣的图像，经过一系列的图像预处理，然后利用轮廓上两点之间的最大距离来测量纵向直径。最后，实现粒度分级。实验结果表明，该分级系统速度快、结构简单、成本低，在红枣质量检测和分级中具有较高的实用价值。
Using the high-performance and low-cost feature of STM32F407,combining with the embedded machine vision technology,designed a jujubes embedded machine visual grading system. Firstly,got fresh jujube image by camera,through a series of image preprocessing,and then used the maximum distance between two points on the contour to measure longitudinal diameter.Finally,realize the size-grading.The experimental result showed that the grading system was high-speed,simple-structure and low-cost,and had high practical value in jujube quality detection and classification.
