Simple strawberry leaf transpiration rate acquisition method based on images

The invention discloses an image-based strawberry leaf transpiration rate simple acquisition method. The method comprises the following steps: carrying out natural light treatment on strawberry leaves; collecting a clear image of the strawberry leaf under a natural illumination condition; extracting RGB parameters of the clear image, wherein the RGB parameters comprise 24-bit true color parameters; constructing a transpiration rate estimation model; and inputting the extracted RGB parameters as model factors into the transpiration rate estimation model to obtain the transpiration rate of the strawberry leaves. According to the simple acquisition method for the transpiration rate of the strawberry leaf based on the image, accurate, rapid and low-cost transpiration rate nondestructive testing of the strawberry leaf can be realized. 本发明公开了一种基于图像的草莓叶片蒸腾速率简易获取方法，包括以下步骤：对草莓叶片进行自然光照处理；采集自然光照条件下的所述草莓叶片的清晰图像；提取所述清晰图像的RGB参数，所述RGB参数包括24位真彩色参数；构建蒸腾速率估算模型；将提取的所述RGB参数作为模型因子输入所述蒸腾速率估算模型，获取所述草莓叶片的蒸腾速率。本发明的基于图像的草莓叶片蒸腾速率简易获取方法
