针对复杂背景下的成熟草莓图像,提出了一种基于RGB颜色相似度的成熟草莓图像分割算法(CSBASED RSIS) 。首先提取成熟草莓区域,确定成熟草莓的主颜色,然后遍历待分割的图像,求出每个像素点相对于主颜色的颜色比和相似度,进行颜色相似度的阈值分类,最后经多次膨胀和去除小面积对象的数学形态学处理,输出分割结果。试验结果表明,在无粘连无遮挡、无粘连有遮挡、有粘连有遮挡3种复杂环境下,与OTSU等图像分割算法相比,CS-BASED RSIS算法不仅能达到更好的分割效果,而且平均分割时间仅为0.965 s,能满足成熟草莓机械化采摘的实时性要求。

In view of the limitations of traditional simple threshold algorithms under the complicated background,a ripe strawberry image segmentation algorithm based on RGB color similarity (CS-BASED RSIS) was proposed. Firstly, ripe strawberry regions were extracted,which determined the main color of ripe strawberry. Then,the CS-BASED RSIS algorithm traveled all pixels in the image for segmentation,calculated the color ratio and similarity of each pixel point relative to the main color,and threshold classification on color similarity were carried out. Finally,the image was processed with the multiple e...
