The dynamic image of seed on conveyer belt was gathered, and the image edge was detected with mathematical morphological operators. The results showed that the extraction result of this method on seed image edge was accurate than that of the traditional edge detection method.%采集种子在传送带上的动态图像,运用数学形态学算子对图像边缘进行检测.结果显示,与传统的边缘检测算法相比,该方法可准确提取种子图像边缘,且具有很强的抗噪能力.
