基于HIS颜色特征的田间成熟番茄识别技术

Discrimination of Mature Tomato Based on HIS Color Space in Natural Outdoor Scenes

研究了一种基于 HIS颜色特征的田间成熟番茄识别技术。将计算机视觉系统获取的番茄 RGB图像转换成 HIS图像 ,通过统计 H、I、S分量的灰度分布找出成熟番茄、未成熟番茄和叶子 (枝干 )灰度分布差别 ;然后根据 H分量的灰度分布用阈值法分割出成熟番茄区域 ;经过空洞填充后 ,计算出番茄质心坐标。该方法对田间成熟番茄之间相互分离的情况有很好的识别效果。

The discrimination of mature tomato in natural outdoor scenes using HIS color space was studied in this paper. The differences of gray level for components H, I, and S were calculated after converting the obtained RGB image into HIS image. The region of mature tomato in the image was segmented out by H gray level threshold and the coordinate values of the tomato centroid were calculated after filling the vacancy. The method is valid for discriminating the individual mature tomatoes in natural outdoor scenes.
