| 摘 要： | 针对水稻稻田图像中秧苗和背景分割问题,采用基于最大类间方差法(OTSU法)的分割方法,成功地把水稻秧苗像素和背景像素分割开.首先用CCD相机获取水稻插秧机插秧作业后的水稻稻田图像,选择超绿特征因子(EXG因子)将水稻秧苗RGB彩色图像转化为灰度图像,使用OTSU法计算阈值,成功地将灰度图像转变为二值图像.又采用该方法分割了20幅水稻秧苗图像,结果表明,EXG因子可以对水稻秧苗图像有效分割. |

| Abstract: | For segmentation of rice seeding and background in paddy field images,a segmentation method based on OTSU was adopted,and rice seeding pixels were segmented from background pixels successfully.The images of paddy field transplanted by rice transplanter were acquired with CCD camera,EXG factor was selected to transfer rice seedling RGB color image into gray image,the threshold value was calculated with OSTU method,then the paddy images were segmented into binary image.The results showed that the method was very effective in segmentation rice seeding images. |
