中文摘要:针对水平棚架栽培模式下采集的单幅葡萄果树图像,提出了结合葡萄颜色与形状特征的目标识别定位方法,获得果穗的中心线和长度特征参数。通过提取葡萄图像的|G-R|+|G-B|色差图,利用Sobel算子进行边缘提取。构建葡萄果粒轮廓的数学模型进行Hough变换,实现葡萄果粒的初步识别。结合葡萄果穗的颜色、纹理特征以及果粒分布较为集中的特点判断Hough变换检测出的圆区域是否为果粒。综合利用识别出的果粒信息找到葡萄图像的外接矩形完成目标提取。对78幅图像进行测试,正确识别出葡萄区域的图像为70幅,正确识别率约为90%。

Abstract:Aimed at the image of the simple grapevine taken in the pergola trellis, a grape recognition algorithm combined with color and texture feature of color image was suggested in order to get the center line and the length of the grape. Firstly, Sobel operation was used to get the edge of the |G-R|+|G-B| chromatic aberration image. Then, berries of the grape were detected by Hough transform according to the mathematical model of the outline of the grape berries. The circles detected by the Hough transform were judged by the feature of the color and texture of grape berries and the concentrated berries. At last, the shape parameters of the grape bunch were determined by the information of the berries after judged, which was needed by bagging automation of grape. The experimental results showed that the method of grape recognition was effective in segmenting the comparison of grapes. There were totally 78 images used in test, and 70 of them were correctly recognized. The correct recognition of grapes reached to 90%.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
