Abstract

The present invention discloses a method for analyzing the leaf area of ​​living long leaves based on image stitching, comprising the following steps: in response to receiving a request to calculate the leaf area, segmenting the leaf image to be analyzed to obtain a color segmented image of the leaf, wherein the leaf image to be analyzed is a leaf image in which at least one-fifth of adjacent images are repeated; stitching all the color segmented images of the leaf in pairs to obtain a complete leaf image; obtaining the outer contour of the leaf through the complete leaf image, and obtaining relevant parameters of the leaf, wherein the relevant parameters are one or more of the leaf area, leaf circumference, leaf length and width, shape factor and shape coefficient. The method has high measurement accuracy, is simple, does not damage the leaf, is easy to carry, can be used indoors and outdoors, and has strong anti-interference ability. The leaf result obtained by the invention is a color image, which not only retains the leaf characteristics, but also facilitates the subsequent analysis of leaf insect damage, lesions and other characteristics.
