摘要
在自然光条件下,利用计算机图像处理技术对温室黄瓜幼苗的生长信息进行了检测研究。提取作物的外部形态特征:叶片颜色和仰角,在RGB和HIS颜色模型下,分析了土壤水分含量与各颜色分量、叶片仰角之间的相关性。结果表明:土壤的水分含量与叶片的仰角、G分量和H分量有很好的相关性,决定系数分别达到0．9187、0．8404和0．8822,可作为利用机器视觉检测黄瓜植株生长信息的指标。该研究对于提高温室的智能化控制水平具有重要的意义。
Measurement for cucumber seeding growth information was studied using computer image processing techniques under the sunlight condition.The correlations between the leaf color parameters,leaf elevation and water content of soil are anal- yzed under the RGB and HIS model.The result shows that there are high linear correlations between the leaf color parameters,leaf elevation and water content of soil,the correlation of R are 0.9585、-0.9167 and 0.9392,which could be used as the indices of me- asurement for cu...
