摘要：采用中国特有乡土树种文冠果生长初期的逐日图像,探讨植物体像素抽取算法,根据苗木逐日像素的变化分析植物的生长过程。结果表明:根据图像中前景像素变化来研究植物动态规律是一个很好的办法;苗木生长初始月份,理查德曲线可以很好地拟合文冠果苗木的像素生长过程。为文冠果苗木培育提供基础技术参考,也为该领域物联网图像的使用提供一些方法性指导。
With initial growth stage images of shinyleaf yellowhom, which is a kind of native species grown in China, plant pixels extraction algorithm was discussed. According to the day by day changes of the values of plant pixels, the dynamic rules of plant growth were analyzed. Several conclusions were obtained as follows： It is a good method for studying dynamic rules of plant growth according to the changes of the pixel values of foreground in image; In the initial month of seedlings growth, Richard curve can well simulate the process of pixel growth of shinyleaf yellowhom seedlings. The purposes of this research were to provide reference data for cultivation of shinyleaf yellowhom seedlings, and also provide methodological guidance for the further application of the intemet of things based on image in this area.
